Description

[0001] This application is a divisional application of Chinese patent application No. 201780011040.8 (“Electronic Device with Loop Antenna”). Technical Field

[0002] This disclosure generally relates to electronic devices having a loop antenna, and more specifically, to electronic devices using a loop antenna to transmit magnetic field signals containing, for example, payment information. Background Technology

[0003] A typical card reader (e.g., a point-of-sale (POS) terminal) includes a head and a coil for reading information stored in the track of a magnetic stripe on a magnetic card. Card data is recorded in the track of the magnetic stripe on the card, and the track may include a start mark (SS), an end mark (ES), and longitudinal redundancy check (LRC) characters.

[0004] When the reader swipes the paper across the reader's rail, the magnetic flux through the coil coupled to the rail changes. This change in magnetic flux causes a current to flow through the reader. This current enables the reader to read and process the card data recorded on the rail.

[0005] Electronic devices can be equipped with modules for magnetic field communication. These modules allow electronic devices to perform magnetic field communication with other devices. Summary of the Invention

[0006] Technical issues

[0097] Figure 1B This is a block diagram illustrating the configuration of an electronic device capable of performing payment functions according to an embodiment of the present disclosure.

[0098] refer to Figure 1B The electronic device 100 includes a camera module 101, an accelerometer sensor 103, a gyroscope sensor 105, a biosensor 107, an MST module 110, an NFC module 120, an MST control module 130, an NFC control module 140, a processor 150, and a memory 160.

[0099] In embodiments of this disclosure, camera module 101 captures an image of the card for payment and obtains card information. Camera module 101 is capable of recognizing card information recorded on the card (e.g., card issuer, card number, expiry date, cardholder's name, etc.) via an optical character recognition (OCR) function. Alternatively, the user can directly input the card information into his / her electronic device using an input device of the electronic device (e.g., touch panel, pen sensor, keys, ultrasonic input system, microphone, etc.).

[0100] In embodiments of this disclosure, the accelerometer 103 or gyroscope 105 can obtain location information about the electronic device during payment and transmit the obtained location information to the processor 150. The processor 150 controls the current supplied to the antenna (e.g., a coil antenna) of the MST module 110 based on the location information about the electronic device to control the magnetic field strength transmitted to the POS terminal. Alternatively, when the MST module 110 has multiple coil antennas, the processor 150 can select which coil antenna to use.

[0101] In embodiments of this disclosure, the biosensor 107 is able to obtain user biometric information (e.g., fingerprint or iris information) to authenticate a card or user used for payment.

[0102] In embodiments of this disclosure, the MST module 110 may include a coil antenna. The MST control module 130 may supply voltages with different polarities to the ends of the coil antenna based on data (e.g., binary values, 0 or 1), thereby controlling the direction of the current flowing in the coil antenna. The signal emitted from the coil antenna (or the magnetic field signal induced by the current flowing in the coil) generates an induced electromotive force in the POS terminal, as if the POS terminal had read a magnetic card.

[0103] In embodiments of this disclosure, the MST control module 130 includes a data receiving module 131 and an output conversion module 133. The data receiving module 131 is capable of receiving logic high / low pulses containing payment information from the processor 150 (or the built-in security module of the electronic device 100).

[0104] In embodiments of this disclosure, the output conversion module 133 is implemented using circuitry capable of converting data recognized by the data receiving module 131 into data of a corresponding format to be sent to the MST module 110. This circuitry may include an H-bridge configured to alternate the polarity of the voltage supplied to the MST module 110.

[0105] In embodiments of this disclosure, electronic device 100 can receive information about a card via camera module 101 or an input device (e.g., touch panel, pen sensor, etc.), and based on the card information, receive payment information (e.g., track 1, track 2, track 3, or token information) contained in at least a portion of the magnetic stripe of the card (e.g., magnetic stripe card) from a card issuing company / bank server via a communication module. Electronic device 100 can store the payment information in a corresponding format in processor 150 or a built-in security module.

[0106] Figure 2A This is a diagram illustrating an MST signal transmitted from an MST module according to an embodiment of the present disclosure. Figure 2B A diagram illustrating the pulse timing of an MST signal according to an embodiment of the present disclosure is shown. In this document, "pulse timing" refers to the time interval from the start of a pulse to the start of the next pulse, also referred to as "pulse duration" or "duration".

[0107] refer to Figure 2A Electronic devices (e.g.) Figure 1BThe electronic device 100 is capable of transmitting an MST signal containing payment information multiple times (e.g., N times, where N is a positive integer) via the MST module in each period T. Each of the transmitted MST signals (first MST signal 200_1 to nth MST signal 200_n) may contain a logic low / high pulse corresponding to a binary value of 0 or 1. For example, when the voltage formed in the pulse does not change in level within the time period t, the state represents "0", i.e., logic low. When the level (or phase) of the voltage formed in the pulse changes, the state represents "1", i.e., logic high.

[0108] In embodiments of this disclosure, the MST module is capable of periodically transmitting the same MST signal. For example, the MST signal may contain payment information recorded in at least a portion of the card. Figure 2A As shown, each of the MST signals 200 (i.e., the first MST signal 200_1 to the nth MST signal 200_n) may contain at least a portion of the following information regarding the card, track 1, track 2, track 3, and token. For example, each of the first MST signals 200_1 to the nth MST signal 200_n may contain two or more of the following information regarding the card, track 1, track 2, track 3, and token.

[0109] In embodiments of this disclosure, the MST module can periodically transmit other MST signals. For example, when transmitting MST signal 200, the first MST signal 200_1 to the nth MST signal 200_n can contain track information items that are different from each other. For example, each of the MST signals (e.g., MST signals 200_1 to 200_n) can contain information items from two or more of the card tracks (track 1, track 2, and track 3) recorded below.

[0110] When MST signal 200 is transmitted, MST signals 200_1 to 200_n can have different formats from each other. For example, MST signals can have different pulse timings or periods T.

[0111] refer to Figure 2B Electronic devices (e.g.) Figure 1BThe electronic device 100 shown is capable of transmitting MST signals containing payment information via an MST module at different pulse timings t. In embodiments of this disclosure, the MST signals (e.g., MST signals 200_1 to 200_n) can have different pulse timings t. For example, the first MST signal 200_1 may contain at least a portion of the following card information tracks 1, 2, 3, and token, and in this case, each pulse may have a pulse timing of 300 μs. The second MST signal 200_2 may contain at least a portion of the following card information tracks 1, 2, 3, and token, and in this case, each pulse may have a pulse timing of 500 μs. When the pulse timing t is small, an external device (e.g., a POS terminal) can receive a signal from the electronic device that is similar to the signal when a cardholder quickly swipes their card on the external device. On the other hand, when the pulse timing t is large, an external device (e.g., a POS terminal) can receive a signal from the electronic device that is similar to the signal when a cardholder slowly swipes their card on the external device.

[0112] In embodiments of this disclosure, the period T is variable. For example, each of the first MST signal 200_1 and the second MST signal 200_2 may include at least a portion of the following card information tracks 1, 2, 3, and token, and the first MST signal 200_1 and the second MST signal 200_2 may be transmitted once per second. Each of the third MST signal 200_3 and the fourth MST signal 200_4 may include at least a portion of the following card information tracks 1, 2, 3, and token, and the third MST signal 200_3 and the fourth MST signal 200_4 may be transmitted once every two seconds.

[0113] When transmitting the MST signal, the NFC module (e.g., Figure 1B The NFC module 120 can operate in polling mode.

[0114] Figure 3 The illustration shows a string included in payment data corresponding to payment information, according to an embodiment of this disclosure.

[0115] refer to Figure 3 (a) and (b), electronic devices (e.g., Figure 1B The electronic device 100 is capable of transmitting signals containing payment data (e.g., payment information) at a period T (e.g., once per second) using the MST module. For example, a signal transmitted once per second may contain, for example, Figure 3 The information about orbit 1 shown in (a), or as in Figure 3The information about orbit 2 is shown in (b). For example, a signal transmitted once per second may contain a portion of the information about orbit 1 as shown in (a) or information about orbit 2 as shown in (b).

[0116] Figure 4 A binary string encoded from information is shown according to an embodiment of the present disclosure.

[0117] refer to Figure 4 (a) shows Figure 3 The binary string of data shown in (a) may include a Longitudinal Redundancy Check (LRC) character at the end (tail), for example, "0111000". Figure 4 (b) shows Figure 3 The binary string of data shown in (b) may contain an LRC at the end (tail), for example, "11111".

[0118] Figure 5 Track information transmitted via the transmission of an MST signal according to an embodiment of the present disclosure is shown.

[0119] refer to Figure 5 The data shown in (a) is created, for example, by adding "00000000" to... Figure 4 The leading and trailing data of the binary string of (a). Figure 5 The data shown in (b) is created, for example, by adding "00000000" to... Figure 4 (b) is the data at the beginning and end of the binary string.

[0120] In embodiments of this disclosure, electronic devices (e.g., Figure 1B The electronic device 100 is capable of transmitting information about a track via the MST module at a period T; this transmission is referred to as a simple sequence. For example, the electronic device can transmit information about track 1 via the MST module at a period T (e.g., Figure 5 The data shown in (a) or information about orbit 2 (e.g., Figure 5 The data shown in (b) includes the MST signal. The electronic device is capable of transmitting a signal containing information about multiple orbits at a period T, and this transmission is called a composite sequence. Implementation schemes for simple and complex sequences are described below.

[0121] Figure 6 A method for including multiple orbital information items in an MST signal according to an embodiment of the present disclosure is shown.

[0122] refer to Figure 6 (a) The electronic device will Figure 5 (a) shows orbital data 601 and Figure 5 (b) shows that the orbital 2 data 602 are sequentially lumped together to configure a data item, and the configured data is transmitted within one period T. For example, Figure 6 The data shown in (a) can be included Figure 2A At least one of the MST signals 200 shown in the figure.

[0123] refer to Figure 6 (b) The electronic device is capable of configuring at least a portion of the MST signal by arranging the binary numbers of data from at least one track in reverse order. For example, the electronic device configures the data in reverse order. Figure 5 The binary number of track 1 data shown in (a) is used to create inverted track 1 data 603. The electronic device sequentially... Figure 5 The track 2 data 604 shown in (b) is merged with the reversed track 1 data 603 into a single data item, and the merged data is transmitted within one period T. The reversed track 1 data 603 has the same effect as a cardholder swiping a card in the opposite direction on an external device.

[0124] refer to Figure 6 (c) The electronic devices sequentially will Figure 5 (b) shows track 2 data 602, when configured in reverse order. Figure 5 The inverted orbital 1 data 603 created when (a) is orbital 1 data, and Figure 5 (b) The orbital 2 data 602 is merged to create a data item, and the merged data is emitted within one period T. It should be understood that the merging or combination of orbital data can also be performed in various ways other than those described above. For example, orbital 2 data and inverted orbital 2 data can be merged sequentially.

[0125] Therefore, the electronic device is able to include track information in various formats in at least one of the MST signals 200 periodically emitted by the MST module.

[0126] Figure 7 This is a diagram illustrating a simple transmission sequence and a composite transmission sequence according to embodiments of the present disclosure.

[0127] refer to Figure 7 Electronic devices (e.g.) Figure 1B The electronic device 100 is capable of performing transmission in a first simple transmission sequence 710. For example, the electronic device periodically transmits four consecutive times information containing orbit 2 (e.g., Figure 5The MST signal of (b) is a pulse timing signal, where each pulse is one second (or period T1). The width W of the MST signal is determined based on the pulse timing. For example, the pulse timing of the first simple transmission sequence 710 is set to 300 μs.

[0128] The electronic device is capable of transmitting in a first composite transmission sequence 720. For example, the electronic device transmits an MST signal four times consecutively (period T2), where the MST signal contains information about track 1 and the reversed track 2 (e.g., data created by sequentially merging track 1 data 601 and the reversed track 2 data created when track 2 data 602 is configured in reverse order). The electronic device reduces the pulse timing of the first composite transmission sequence 720 to equalize period T2 to period T1. As another example, the electronic device can equalize the pulse timing of the first composite transmission sequence 720 to the pulse timing of the first simple transmission sequence 710. In this case, the amount of information transmitted in period T2 is greater than the amount of information transmitted in period T1, and thus the width W2 is also greater than W1. Therefore, when the intervals I2 and I1 are set to be the same, period T2 is greater than period T1. When the electronic device reduces the interval I2 to less than I1, period T2 can be the same as period T1.

[0129] The electronic device is capable of performing transmission using a second simple transmission sequence 730. For example, the electronic device transmits information containing orbit 2 (e.g., ...) four consecutively periodically (period T3). Figure 5 The MST signal of (b) data. In this case, the pulse timing of the second simple transmission sequence 730 can be greater than the pulse timing of the first simple transmission sequence 710. For example, the first simple transmission sequence 710 has a pulse timing of 300 μs, and the second simple transmission sequence 730 has a pulse timing of 500 μs.

[0130] The electronic device is capable of performing transmission in the second composite transmission sequence 740. For example, the electronic device transmits the MST signal four consecutively periodically (period T4), wherein the MST signal contains information about track 1 and the reversed track 2 (e.g., when configured in reverse order). Figure 5 The data in (a) and Figure 5 (b) The data is created when the data is in binary form. In this case, the pulse timing of the second composite transmission sequence 740 can be greater than the pulse timing of the first composite transmission sequence 720. For example, the first composite transmission sequence 720 has a pulse timing of 300 μs, and the second composite transmission sequence 740 has a pulse timing of 500 μs.

[0131] According to embodiments of this disclosure, electronic devices (e.g., Figure 1BThe MST control module 130 of the electronic device 100 can adjust the pulse timing. Alternatively, the electronic device (e.g., Figure 1B The MST control module 130 of the electronic device 100 shown can adjust the period of the MST signal. Alternatively, the electronic device can perform transmission with a simple transmission sequence. Alternatively, the electronic device can perform transmission with a composite transmission sequence. Alternatively, the electronic device can combine simple transmission sequences and composite transmission sequences and perform these processes. For example, as... Figure 7 As shown, the electronic device combines simple transmission sequences with composite transmission sequences 16 times within 20 seconds. It should be understood that this disclosure is not limited to using 16 times as the number of occurrences or 20 seconds as the time period. With respect to at least one of the following types of data, periods, and pulse timing, one MST signal and other MST signals can be different from each other. For example, while one MST signal has a one-second signal transmission period, another MST signal has a signal transmission period of any other value, but not one second.

[0132] The MST signal can be modified and transmitted according to the state of the electronic device. For example, the electronic device obtains its location information (e.g., country code, Internet Protocol (IP) address, GPS data, etc.), uses the obtained location information to identify its location, and determines the signal generation conditions (e.g., sequence combination, period, pulse timing, etc.) corresponding to the identified location. For example, if a condition table is already stored in the memory of the electronic device, the processor obtains the conditions corresponding to the identified location from the condition table. The electronic device creates the MST signal based on the determined conditions. The electronic device determines the remaining battery capacity or battery temperature. When the battery is depleting its power or the temperature is rising, the electronic device can first transmit a simple transmission sequence. The electronic device can modify at least one of the following transmission period, pulse timing, and sequence, and transmit the MST signal via cellular communication. For example, when the electronic device is implemented to perform GSM, it can adjust the transmission period of the MST signal so that the MST signal is not affected by the Time Division Multiple Access (TDMA) period.

[0133] The MST signal can be modified and transmitted via an external device located near the electronic device. For example, the electronic device (User Equipment (UE)) receives characteristics of the POS terminal related to, for example, track, transmission period, etc., from a beacon terminal installed in the store, and adjusts at least one of the following transmission period, pulse timing, and sequence based on the received values.

[0134] According to embodiments of this disclosure, an electronic device modifies and transmits a modified MST signal based on the type of card selected for payment. For example, a specific type of card (e.g., a Private Label Credit Card (PLCC)) can only be used at a preset store. When a card usable at a preset store is selected, information about the selected card is sent to an external device (e.g., a payment server). In this case, the external device uses the received card information to identify the store and sends MST signal information corresponding to the store information to the electronic device. The electronic device uses the MST signal information received from the external device to modify at least one of the following transmission period, pulse timing, and sequence, and transmits the MST signal. The MST signal information can be stored in the electronic device. For example, the electronic device has already received MST signal information corresponding to the store from the external device (e.g., a payment server). In this case, when a card usable only at a preset store is selected, the electronic device identifies the store information via the selected card information, determines the MST signal information corresponding to the identified store information, modifies at least one of the following transmission period, pulse timing, and sequence to satisfy the MST signal information, and transmits the MST signal.

[0135] Figure 8 This is a diagram illustrating an electronic device capable of performing payment functions using MST according to an embodiment of the present disclosure.

[0136] refer to Figure 8 The MST data transmission module 810 is capable of transmitting the information required for payment (e.g., Figure 5 (a) and (b) or Figure 6 The data shown in (a) and (b) is sent to the MST control module 820. The MST data transmission module 810 may be a processor or a secure area within a processor. The MST data transmission module 810 may also be embedded in an electronic device (e.g., Figure 1BThe security module (embedded security element (eSE) / universal integrated circuit card (UICC)) in the electronic device 100. The MST data transmission module 810 is capable of sending control signals 812 and data pulses 811 to the MST control module 820 for the time required to activate the MST output module 830 (e.g., the time period required to transmit a preset number of MST signals). The MST data transmission module 810 is capable of sending differential data pairs with different phases. The MST data transmission module 810 distinguishes the track 1, track 2, or track 3 data contained in the magnetic card from each other based on time and sends them sequentially. Alternatively, the MST data transmission module 810 interleaves the track 1, track 2, or track 3 data and sends the interleaved result. The MST data transmission module 810 reverses at least a portion of the track 1, track 2, or track 3 data (e.g., changing the order of 11110101 to 10101111) and then sends the result. The MST data transmission module 810 can sequentially send a first simple transmission sequence 710, a first composite transmission sequence 720, a first simple transmission sequence 730, and a second composite transmission sequence 740, such as... Figure 7 As shown.

[0137] According to embodiments of this disclosure, the data receiving module 822 of the MST control module 820 can identify the state (logic low / high) of the received pulse data as data (e.g., binary values ​​0 or 1). Alternatively, the data receiving module 822 detects the number of transitions between low and high states within a preset time period and identifies the result as data. For example, when the data receiving module 822 determines that the number of transitions between low and high states within the preset time period is 1 and 2, it identifies the result as '0' (zero) and '1' (one) binary values, respectively.

[0138] The output conversion module 821 of the MST control module 820 includes circuitry for converting data recognized by the data receiving module 822 into the form required for transmission to the MST module 230. This circuitry includes a first switch S1, a second switch S2, a third switch S3, and a fourth switch S4. The first switch S1 and the fourth switch S4 may have the same control state, and the second switch S2 and the third switch S3 may have the same control state. Depending on the control state of the switches, the direction of the voltage supplied to the opposite ends of the coil antenna 831 can be changed. At this time, the voltage level supplied to the coil antenna 831 can be Vm. For example, in the zero-bit case, the data receiving module 822 can turn on the first and fourth switches and turn off the second and third switches, and vice versa. In the one-bit case, the data receiving module 822 can turn off the first and fourth switches and turn on the second and third switches, and vice versa. The output conversion module 821 can change the direction of the voltage (direction of current) supplied to the opposite ends of the coil antenna L according to the data recognized by the data receiving module 822, thereby changing the direction of the magnetic field transmitted through the coil antenna L to an external device (e.g., a POS terminal). For example, in the zero-bit case, the voltage level at coil antenna 831 can be Vm, and the current direction can be along the 'A' direction. In the one-bit case, the voltage level at coil antenna 831 can be Vm, and the current direction can be along the 'B' direction (the direction opposite to 'A'). The magnetic field generated by the coil antenna can be similar in form to the magnetic field generated when a magnetic card is swiped through a POS terminal. Switches S1, S2, S3, or S4 can be N-type MOSFETs (metal-oxide-semiconductor field-effect transistors), P-type MOSFETs, or relays.

[0139] In embodiments of this disclosure, the MST output module 830 may include a coil antenna L. The MST output module 830 may also include an inductor, capacitor, resistor, etc. In embodiments of this disclosure, the MST output module 830 may also include an amplifier for amplifying signals. The coil antenna L may also be used for NFC or wireless charging. In embodiments of this disclosure, the module may employ multiple coil antennas.

[0140] Figure 9 This is a diagram illustrating the results of measuring the signals transmitted from the MST output module and the signals received by an external device according to an embodiment of the present disclosure.

[0141] refer to Figure 9 When the MST output module (e.g., Figure 8When the MST output module 830 shown transmits an MST signal 920 containing payment data, an external device (e.g., a POS terminal) receives the signal 920 and identifies the data 910 based on the transition (e.g., rise time) of the MST signal 920. To improve the recognition rate of the MST signal, the coil antenna can be optimized using inductance value and number of turns. For example, the inductance value can be greater than or equal to 10 μH.

[0142] Figure 10A and Figure 10B This is a diagram illustrating an electronic device with a flat loop antenna according to an embodiment of the present invention. Figure 10A The current path in the rear surface of the electronic device and in the loop antenna is shown. Figure 10B A schematic cross-section of an electronic device and the magnetic field generated by a loop antenna are shown.

[0143] refer to Figure 10A and Figure 10B The electronic device 1000 (e.g., electronic device 11) includes a cover 1010, a loop antenna 1020, a connection module 1030, a communication module 1040, and a substrate 1050.

[0144] The cover 1010 forms the rear surface of the electronic device 1000 and may be made of a non-conductive material (e.g., plastic or glass). The cover 1010 may have holes for exposing specific components of the electronic device 1000. For example, the camera 1061 may be exposed through a first hole, and the flash and sensor 1062 may be exposed through a second hole.

[0145] The loop antenna 1020 can be implemented using a flat coil spirally wound relative to the Z-axis. Therefore, the loop antenna 1020 can generate a magnetic field in a direction perpendicular to the rear surface (XY plane) of the electronic device 1000 (Z-axis). The flat coil can be contained in a flexible printed circuit board (FPCB) 1070. The FPCB 1070 can be attached to the bottom surface of the cover 1010.

[0146] The connection module 1030 may include various circuits. For example, the circuit may consist of passive components, active components, striplines, microstrip lines, or interdigitated structures, or combinations thereof. The circuit can vary the impedance corresponding to the loop antenna 1020 based on characteristic values ​​(e.g., capacitance, inductance, or resistance). Passive components may include capacitors, inductors, and resistors. Active components may include field-effect transistors (FETs) and bipolar junction transistors (BJTs). The interdigitated structure may be a chip or package of passive or active components and may be mounted on the substrate 1050. The circuit can compensate for the physical dimensions of the loop antenna 1020 by adjusting its electrical length.

[0147] The communication module 1040 can use the loop antenna 1020 to perform data communication with another electronic device connected to the electronic device 1000 via a network.

[0148] The substrate 1050 can provide electrical signals to the loop antenna 1020. The substrate 1050 can be implemented using a printed circuit board (PCB) and / or a freeform PCB. The substrate 1050 can feed current to and receive current from the loop antenna 1020. The substrate 1050 can serve as a ground plane to ground the loop antenna 1020. The connection module 1030 and the communication module 1040 can be mounted on the substrate 1050 and electrically connected together via wires. The connection module 1030 and the communication module 1040 can be electrically connected to the loop antenna 1020 via a first connection terminal 1081 and a second connection terminal 1082, respectively. For example, the first connection terminal 1081 and the second connection terminal 1082 can make electrical contact with a first feed point 1021 and a second feed point 1022 of the loop antenna 1020, respectively. The first connection terminal 1081 and the second connection terminal 1082 can each be a resilient pin (e.g., a C-clamp).

[0149] The substrate 1050 may include a dielectric material, such as a first dielectric 1051 and a second dielectric 1052. A first connection terminal 1081 and a second connection terminal 1082 may be mounted on the first dielectric 1051 and the second dielectric 1052, respectively. The first connection terminal 1081 can be connected to the connection module 1030 via a first capacitor 1053, and the second connection terminal 1082 can be connected to the communication module 1040 via a second capacitor 1054. The first capacitor 1053 and the second capacitor 1054 are used to prevent electric shock and may have a capacitance of 10 to 1000 pF.

[0150] When current is supplied from the communication module 1040 to either the first feed point 1021 or the second feed point 1022 of the loop antenna 1020, the current flows from the corresponding feed point (e.g., the first feed point 1021) to the other feed point (e.g., the second feed point 1022), thereby forming a spiral current path 1091 relative to the Z-axis. This current path 1091 can generate a magnetic field 1092 along the Z-axis direction perpendicular to the rear surface (XY plane) of the electronic device 1000. A specific signal (i.e., resonance) with a frequency corresponding to the length of the loop antenna 1020 (i.e., the length of the current path 1091) can be selected, and the selected signal can be transmitted to the outside of the electronic device 1000 through a cover 1010 made of a non-conductive material. According to the reciprocity principle, the loop antenna 1020 can receive RF signals with a specified frequency, convert the received RF signals into current, and forward the current to the communication module 1040.

[0151] Figures 11A to 11FThis is a diagram illustrating an electronic device having a solenoid-type loop antenna according to an embodiment of the present disclosure. Figure 11A The rear surface of the electronic device is shown. Figure 11B The front surface of the electronic device is shown. Figure 11C A schematic cross-section of the electronic device is shown. Figure 11D A schematic front view of a loop antenna is shown. Figure 11E A schematic cross-sectional view of a loop antenna is shown. Figure 11F A schematic cross-section of an electronic device, the current path in a loop antenna, and the magnetic field generated by the loop antenna are shown.

[0152] refer to Figures 11A to 11C Electronic device 1100 (e.g., electronic device 11) includes a loop antenna 1120, a connection module 1130 (e.g., connection module 1030), a communication module 1140 (e.g., communication module 1040), and a substrate 1150. These components 1120 to 1150 can be arranged within a housing of electronic device 1100. The housing may include a first surface 1110 along a first direction, a second surface 1160 along a second direction opposite to the first direction, and a side member 1170 surrounding the space between the first surface 1110 and the second surface 1160. For example, the first surface 1110 may be a cover constituting the rear surface of electronic device 1100, and the second surface 1160 may be a cover constituting the front surface of electronic device 1100. Display 1161 may be exposed to the outside through the second surface 1160. The second surface 1160 and the side member 1170 may be formed as a single entity.

[0153] The cover 1110 may be composed of conductive regions made of conductive material and non-conductive regions made of non-conductive material. For example, the cover 1110 may include a first non-conductive region 1111, a second non-conductive region 1112, and a conductive region 1113. The first non-conductive region 1111 and the second non-conductive region 1112 may be arranged such that they are horizontally symmetrical with respect to a central portion, such as... Figure 11A As shown. The remaining area of ​​the cover 1110, excluding the non-conductive areas 1111 and 1112 and the conductive area 1113, may be made of a conductive material. Alternatively, the remaining area of ​​the cover 1110 may be made of a non-conductive material. The cover 1110 may include at least one hole for exposing components of the electronic device 1100 to the outside. For example, three holes may be formed in the first non-conductive area 1111, through which the camera 1161 may be exposed, through the second hole the flash 1162 may be exposed, and through the third hole the sensor 1163 may be exposed.

[0154] A loop antenna 1120 can be disposed below a conductive region 1113 formed between a first non-conductive region 1111 and a second non-conductive region 1112. Specifically, the loop antenna 1120 can be attached to the bottom surface of the conductive region 1113 in an electrically insulating manner. The loop antenna 1120 can have a solenoid coil having multiple turns wound along the Y-axis direction. Therefore, the loop antenna 1120 can generate magnetic flux in the Y-axis direction parallel to the rear surface of the electronic device 1100. (See below for further details.) Figure 11D and Figure 11E The configuration and structure of the solenoid coil are described in more detail.

[0155] The substrate 1150 can provide electrical signals to the loop antenna 1120. The substrate 1150 can be implemented using a PCB and / or an FPCB. The substrate 1150 can feed current to and receive current from the loop antenna 1120. The substrate 1150 can serve as a ground plane to ground the loop antenna 1120. The connection module 1130 and the communication module 1140 can be mounted on the substrate 1150 and electrically connected together via wires. The connection module 1130 and the communication module 1140 can be electrically connected to the loop antenna 1120 via a first connection terminal 1181 and a second connection terminal 1182, respectively. For example, the first connection terminal 1181 and the second connection terminal 1182 can make electrical contact with a first feed point 1121 and a second feed point 1122 of the loop antenna 1120, respectively. The first connection terminal 1181 and the second connection terminal 1182 can each be a resilient pin (e.g., a C-clamp).

[0156] The substrate 1150 may include a dielectric material, such as a first dielectric 1151 and a second dielectric 1152. A first connection terminal 1181 and a second connection terminal 1182 may be mounted on the first dielectric 1151 and the second dielectric 1152, respectively. The first connection terminal 1181 can be connected to the connection module 1130 via a first capacitor 1153, and the second connection terminal 1182 can be connected to the communication module 1140 via a second capacitor 1154. The first capacitor 1153 and the second capacitor 1154 are used to prevent electric shock and may have a capacitance of 10 to 1000 pF. (Reference) Figure 11D and Figure 11EThe loop antenna 1120 can be implemented using an FPCB with multiple layers 1123 to 1125. The top layer 1123 contains multiple conductors 1123a, 1123b, and 1123c constituting a solenoid coil. The bottom layer 1125 contains multiple conductors 1125a, 1125b, and 1125c constituting a solenoid coil. The intermediate layer 1124 includes a conductive via 1124a for constituting the solenoid coil. That is, the conductors on the top layer 1123 can be electrically connected to the conductors on the bottom layer 1125 through the via 1124a, thereby constituting a solenoid coil. The intermediate layer 1124 may include a core 1124b (e.g., μ-metal) to increase the magnetic force generated by the solenoid coil. In another embodiment, the loop antenna 1120 may not have a core 1124b. A processor (e.g., processor 12) can be mounted on the substrate 1150 to control the communication and power supply of the communication module 1140.

[0157] When current is supplied from the communication module 1140 to either the first feed point 1121 or the second feed point 1122 of the loop antenna 1120, the current flows from the corresponding feed point (e.g., the first feed point 1121) to the other feed point (e.g., the second feed point 1122), thereby forming a cylindrical current path 1191 centered on the Y-axis. This current path 1191 can generate a magnetic field 1192 along the Y-axis direction perpendicular to the current direction (i.e., parallel to the rear surface of the electronic device 1100). The magnetic flux of the magnetic field 1192 can pass through the first non-conductive region 1111 and the second non-conductive region 1112 and reach the outside of the electronic device 1100 without being blocked by the conductive region 1113.

[0158] Figure 12 This is a diagram illustrating an electronic device with a solenoid-type loop antenna according to an embodiment of the present disclosure. Specifically, Figure 12 A schematic cross-section of an electronic device and the magnetic field generated by a loop antenna are shown. (Reference) Figure 12 The electronic device 1200 includes a cover 1210, a loop antenna 1220, a connection module (e.g., connection module 1030), a communication module (e.g., communication module 1040), and a substrate (e.g., substrate 1050).

[0159] Cover 1210 forms the rear surface of electronic device 1200 and may be made of a conductive material. Cover 1210 may include at least one hole for exposing components of electronic device 1100 (e.g., camera, flash, or sensor) to the outside. Loop antenna 1220 may be attached to the bottom surface of cover 1210 in an electrically insulating manner and may have a solenoid coil having multiple turns wound along the Y-axis direction (i.e., the horizontal direction relative to the rear surface of electronic device 1200). When current is applied to loop antenna 1220, a cylindrical current path 1291 centered on the Y-axis is formed. This current path 1291 can generate a magnetic field 1292 along the Y-axis direction perpendicular to the current direction. Therefore, the magnetic flux of magnetic field 1292 can bypass cover 1210 and reach the outside of electronic device 1200 without being blocked by cover 1210 made of conductive material.

[0160] Figure 13A and Figure 13B This is a diagram illustrating an electronic device having a plurality of solenoid-type loop antennas according to an embodiment of the present disclosure. Figure 13A The rear surface of the electronic device is shown. Figure 13B The electrical components of the electronic device are shown.

[0161] refer to Figure 13A and Figure 13B Electronic device 1300 (e.g., electronic device 11) includes a first loop antenna 1320, a second loop antenna 1330, a communication circuit 1340, and a processor 1350. These components 1320 to 1350 are disposed within a housing of electronic device 1300. The housing includes a cover 1310 that forms the rear surface of electronic device 1300.

[0162] The cover 1310 may be composed of conductive regions made of conductive material and non-conductive regions made of non-conductive material. For example, the cover 1310 includes a first non-conductive region 1311, a second non-conductive region 1312, and a conductive region 1313. The first non-conductive region 1311 and the second non-conductive region 1312 are arranged such that they are horizontally symmetrical with respect to a central portion. The remaining areas of the cover 1310 other than the non-conductive regions 1311 and 1312 may be made of conductive material. The cover 1310 includes holes 1360, 1362, and 1363 to expose specific components of the electronic device 1300 to the outside.

[0163] A first loop antenna 1320 and a second loop antenna 1330 are disposed parallel to each other below a conductive region 1313 formed between a first non-conductive region 1311 and a second non-conductive region 1312. Each of the first loop antenna 1320 and the second loop antenna 1330 may have a solenoid coil having multiple turns wound along the Y-axis. Both the first loop antenna 1320 and the second loop antenna 1330 may be implemented using an FPCB, such as... Figure 11E As shown. The first loop antenna 1320 and the second loop antenna 1330 generate magnetic fields 1321 and 1331 respectively in a direction parallel to the Y-axis direction of the rear surface of the electronic device 1300. Magnetic fields 1321 and 1331 pass through the first non-conductive region 1311 and the second non-conductive region 1312 respectively, and radiate to the outside of the cover 1310.

[0164] The communication circuit 1340 can convert data from the processor 1350 (e.g., processor 12) into magnetic signals and output the magnetic signals to the first loop antenna 1320 and the second loop antenna 1330. The communication circuit 1340 can be mounted on a substrate and may include... Figures 11A to 11F The connection module 1130 and the communication module 1140.

[0165] Figures 14A to 14C This is a diagram illustrating an electronic device having multiple solenoid-type loop antennas according to an embodiment of the present invention. Figure 14A The rear surface of the electronic device is shown. Figure 14B A cross-section of the FPCB used to implement multiple solenoid loop antennas is shown. Figure 14C The electrical components of the electronic device are shown.

[0166] refer to Figures 14A to 14C The electronic device 1400 includes a solenoid-type first loop antenna 1420, a solenoid-type second loop antenna 1430, a communication circuit 1440, a processor 1450, and a switch 1460. These components 1420 to 1460 are housed within a housing of the electronic device 1400. The housing includes a cover 1410 that forms the rear surface of the electronic device 1400.

[0167] The cover 1410 may be composed of conductive regions made of conductive material and non-conductive regions made of non-conductive material. For example, the cover 1410 includes a first non-conductive region 1411, a second non-conductive region 1412, and a conductive region 1413. The first non-conductive region 1411 and the second non-conductive region 1412 may be arranged such that they are horizontally symmetrical with respect to a central portion. The remaining areas of the cover 1410 other than the non-conductive regions 1411 and 1412 may be made of conductive material. The cover 1410 includes holes 1461, 1462, and 1463 to expose specific components of the electronic device 1400 to the outside.

[0168] A solenoid-type first loop antenna 1420 and second loop antenna 1430 can be implemented using an FPCB 1470. The FPCB 1470 consists of multiple layers 1471 to 1475. The first layer 1471 and the fifth layer 1475 can each contain multiple wires constituting the first loop antenna 1420. These wires can be as follows... Figure 11C The arrangement is shown. The conductors of the first layer 1471 can be electrically connected to the conductors of the fifth layer 1475 through through-holes penetrating the second layer 1471 to the fourth layer 1474. For example, the conductor 1421 of the first layer can be electrically connected to the conductor 1423 of the fifth layer through through-hole 1422. The second layer 1472 and the fourth layer 1474 can each contain multiple conductors constituting the second loop antenna 1430. These conductors can be arranged as follows... Figure 11C The arrangement is shown. The conductors of the second layer 1472 can be electrically connected to the conductors of the fourth layer 1474 through through-holes penetrating the third layer 1473. For example, the conductors 1431 of the second layer can be electrically connected to the conductors 1433 of the fourth layer through through-hole 1432. The first loop antenna 1420 and the second loop antenna 1430 can generate magnetic fields 1424 and 1434, respectively, in directions parallel to the Y-axis direction of the rear surface of the electronic device 1400. These magnetic fields 1424 and 1434 can radiate outwards from the cover 1410 through the first non-conductive region 1411 and the second non-conductive region 1412, respectively. The third layer 1473 may include a core (e.g., a ferromagnetic material such as μ-metal) to increase the magnetic force generated by the solenoid coil.

[0169] The communication circuit 1440 can convert data from the processor 1450 (e.g., processor 12) into magnetic signals and output the magnetic signals to the first loop antenna 1420 and the second loop antenna 1430. The communication circuit 1440 can be mounted on a substrate and may include... Figures 11A to 11FThe connection module 1130 and communication module 1140 are described herein. Electronic device 1400 can selectively output magnetic signals using switch 1460. For example, the magnetic signal can be output to either the first loop antenna 1420 or the second loop antenna 1430 via switch 1460. Processor 1450 can control switch 1460 to output magnetic signals to one or both of the first loop antenna 1420 and the second loop antenna 1430.

[0170] Figure 15A and Figure 15B This is a diagram illustrating an electronic device having a flat and solenoid-type loop antenna according to an embodiment of the present invention. Figure 15A The rear surface of the electronic device is shown. Figure 15B The cross-section of the FPCB used to implement flat and solenoid loop antennas is shown.

[0171] refer to Figure 15A and Figure 15B The electronic device 1500 includes a flat first loop antenna 1520, a solenoid-type second loop antenna 1530, communication circuitry (e.g., communication circuitry 1440), and a processor (e.g., processor 1450). The electronic device 1500 also includes a switch (e.g., switch 1460) to select one of the first loop antenna 1520 and the second loop antenna 1530. These components are housed within a housing of the electronic device 1500. The housing includes a cover 1510 that forms the rear surface of the electronic device 1500.

[0172] The cover 1510 may be made of a non-conductive material (e.g., plastic or glass). The cover 1510 may include holes to expose specific components of the electronic device 1500 to the outside. For example, the camera 1561 is exposed through a first hole, and the flash and sensor 1562 are exposed through a second hole.

[0173] A flat first loop antenna 1520 and a solenoid-type second loop antenna 1530 can be implemented using an FPCB 1540. The FPCB 1540 can consist of multiple layers 1541 to 1543. In the first layer 1541, the first loop antenna 1520 can be implemented using a flat coil wound in a spiral pattern centered on the Z-axis. The first loop antenna 1520 can generate a magnetic field 1512 along the Z-axis direction perpendicular to the rear surface (XY plane) of the electronic device 1500. The first layer 1541 and the third layer 1543 can each contain multiple wires constituting the solenoid-type second loop antenna 1530. These wires can be arranged as follows... Figure 11CThe arrangement is shown. The conductors of the first layer 1541 can be electrically connected to the conductors of the third layer 1543 through through-holes penetrating the second layer 1542. For example, the conductors 1531 of the first layer 1541 can be electrically connected to the conductors 1533 of the third layer 1543 through through-hole 1532. The second loop antenna 1530 can generate a magnetic field 1534 in a direction parallel to the Y-axis direction of the rear surface of the electronic device 1500. Simultaneously, the FPCB 1540 may include a shielding layer (e.g., graphite) to prevent interference between the first loop antenna 1520 and the second loop antenna 1530. For example, a first shielding layer 1550 can be formed on the second layer 1542 to prevent the magnetic signal of the first loop antenna 1520 from affecting the magnetic signal of the second loop antenna 1530. A second shielding layer 1560 can be formed on the third layer 1543 to prevent the magnetic signal of the second loop antenna 1530 from affecting the magnetic signal of the first loop antenna 1520.

[0174] Figures 16A to 16C This is a diagram illustrating the generation of a magnetic field signal for payment according to an embodiment of the present disclosure.

[0175] refer to Figure 16A Electronic device 1600 (e.g., electronic device 11) displays the selected payment card 1610. Electronic device 1600 also displays a guidance message 1620 to guide the payment process. When user authentication (e.g., fingerprint authentication) is completed, electronic device 1600 emits a magnetic field signal 1630 containing card information.

[0176] refer to Figure 16B and Figure 16C To make a payment, the user can bring the electronic device 1600 close to the rail 1641 of the card reader 1640. Here, the successful recognition of the magnetic field signal 1630 may depend on the portion or orientation of the electronic device 1600 near the rail 1641. For example, if the side of the electronic device 1600 is close to the rail 1641 and the screen of the electronic device 1600 is facing a right angle to the rail 1641, the card reader 1640 may not be able to recognize the magnetic field signal 1630. Therefore, to increase the likelihood of successful payment, the electronic device 1600 can not only emit the magnetic field signal 1630 but also display a guiding message indicating the correct orientation of the electronic device 1600 for successful recognition, such as... Figure 16C As shown. Additionally, the electronic device 1600 can use multiple loop antennas to transmit magnetic field signals. For example, the electronic device 1600 can transmit magnetic field signals by alternately or simultaneously using a solenoid-type loop antenna (e.g., a second loop antenna 1530) and a flat loop antenna (e.g., a first loop antenna 1520).

[0177] Figure 17A and Figure 17BThis is a diagram illustrating an electronic device having a solenoid-type loop antenna according to an embodiment of the present disclosure. Figure 17A The rear surface of the electronic device and some internal components are shown. Figure 17B A cross-section of the electronic device is shown.

[0178] refer to Figure 17A and Figure 17B The electronic device may include various electronic components and a housing protecting these electronic components. The housing includes: a first surface 1710 along a first direction, a second surface 1720 along a second direction substantially opposite to the first direction, and a side member 1730 surrounding at least a portion of the space between the first surface 1710 and the second surface. For example, the first surface 1710 may be a cover constituting the front surface of the electronic device, and a display 1741 may be exposed through an area of ​​the cover. The second surface 1720 may be a cover constituting the rear surface of the electronic device. The side member 1730 includes a right side cover 1731 constituting the right side of the electronic device, a left side cover 1732 constituting the left side of the electronic device, a top side cover 1733 constituting the upper side of the electronic device, and a bottom side cover 1734 constituting the lower side of the electronic device.

[0179] refer to Figure 17A The second surface 1720 can be made of a conductive material (e.g., metal), and anodizing can be applied to the second surface 1720 for coloring. The second surface 1720 can be divided into an upper region 1721, a central region 1722, and a lower region 1723. For example, the upper region 1721 and the central region 1722 are divided by an upper slit 1724 formed in a straight line along the X-axis direction (left and right). The central region 1722 and the lower region 1723 are divided by a lower slit 1725 formed in a straight line along the X-axis direction. The second surface 1720 (e.g., a portion of the upper region 1721, the central region 1722, and the lower region 1723) can be electrically connected to a communication module disposed in a housing and can be used as a radiator. The upper slit 1724 and the lower slit 1725 can be filled with a non-conductive material. In the central region 1722, an opening 1726 is formed in the portion near the upper slit 1724 to expose a camera lens to the outside. Another slit 1727, connecting the opening 1726 and the upper slit 1724, is formed between the opening 1726 and the upper slit 1724 along the Y-axis direction (up and down). The slit 1727 may also be filled with a non-conductive material.

[0180] refer to Figure 17BThe display 1741, bracket 1742, camera 1743, battery 1744, loop antenna 1751, metal plate 1752, first substrate 1761, and second substrate 1762 are arranged within the housing. Viewed from the second surface 1720, the display 1741 is disposed on the first surface 1710, and the bracket 1742, designed to support the first surface 1710, is disposed on the display 1741. The camera 1743, battery 1744, first substrate 1761, and second substrate 1762 are disposed on the bracket 1742. Using the housing, the camera 1743 can be disposed below the opening 1726, and the lens of the camera 1743 can be exposed to the outside through the opening 1726. The first substrate 1761 has an opening, and the camera 1743 is exposed through the opening, as shown. Viewed towards the side of the housing (e.g., the right side cover 1731), the battery 1744 is disposed to the right of the camera 1743. Battery 1744 can supply power to various electronic components arranged in the housing (e.g., display 1741, camera 1743) and components mounted on the first substrate 1761 and the second substrate 1762 (e.g., ...). Figure 1B The components shown in the diagram are powered.

[0181] Loop antenna 1751 (e.g., Figures 11A to 11F A loop antenna 1751 is attached to the second surface 1720. Alternatively, an air gap may exist between the loop antenna 1751 and the second surface 1720. Viewed from the second surface 1720, the loop antenna 1751 is disposed on the battery 1744. A metal plate 1752 has a plane substantially parallel to either the first surface 1710 or the second surface 1720 and is disposed on the first substrate 1761 in the region near the upper slit 1724, such as... Figure 17A As shown. The metal plate 1752 has an opening, and the camera 1743 can be exposed through the opening.

[0182] A loop antenna 1751 and a metal plate 1752 are disposed between an upper slit 1724 and a lower slit 1725. For example, one end of the metal plate 1752 may extend to approach or contact one end of the loop antenna 1751, and the other end may extend to approach the upper slit 1724. The other end of the loop antenna 1751 may extend to approach the lower slit 1725.

[0183] The loop antenna 1751 may have a conductor (solenoid coil) wound several times along the X-axis direction (i.e., substantially parallel to the second substrate 1762). The opposite ends of the conductor may be electrically connected to a substrate (e.g., a communication module such as MST module 110 mounted on the first substrate 1761 or the second substrate 1762). The loop antenna 1751 may include a core (e.g., core 1124b) that can amplify the magnetic force generated by the solenoid coil together with the metal plate 1752. The magnetic flux generated by the solenoid coil can diffuse through the core and the metal plate 1752 as a medium to slits 1724 and 1725, and be emitted to the outside through slits 1724 and 1725.

[0184] Figure 18 This is a diagram illustrating an electronic device having a solenoid-type loop antenna according to an embodiment of the present disclosure. Figure 18 Part (a) shows the rear surface of the electronic device. Figure 18 Part (b) shows the internal components arranged below the rear surface. Figure 18 Section (c) together shows the rear surface and internal components.

[0185] refer to Figure 18 In part (a), the cover 1810 may constitute the rear surface of the electronic device and may be made of a conductive material. The cover 1810 may be divided into an upper region 1813, a central region 1814 and a lower region 1815 by an upper slit 1811 and a lower slit 1812.

[0186] refer to Figure 18 Parts (b) and (c), loop antenna 1850 (e.g., Figures 11A to 11F A loop antenna 1120 is disposed below the cover 1810. One end of the loop antenna 1850 extends near the upper slit 1811, while the other end may extend near the lower slit 1812. The upper region 1813 is electrically connected to a first feed point 1821 formed on a first substrate 1820 located below the upper region 1813; the central region 1814 is electrically connected to ground 1822 of the first substrate 1820; and the lower region 1815 is electrically connected to a second feed point 1831 formed on a second substrate 1830. Therefore, the lower region 1815 can act as a first antenna 1841, and the upper region 1813 can act as a second antenna 1842. In addition, when the upper region 1813 is electrically connected to a feed coil 1824 via a third feed point 1823 formed on the first substrate 1820, it can act as a different antenna (e.g., an NFC antenna).

[0187] Figure 19 This is a diagram illustrating an electronic device having a solenoid-type loop antenna according to an embodiment of the present disclosure. Figure 19Part (a) shows the rear surface of the electronic device. Figure 19 Part (b) shows the internal components arranged below the rear surface. Figure 19 Section (c) together shows the rear surface and internal components.

[0188] refer to Figure 19 In part (a), the cover 1920 may constitute the rear surface of the electronic device and may be made of a conductive material. The cover 1920 has an opening 1926 to accommodate an optical sensor (e.g., a camera or PPG sensor) and may be divided into an upper region 1921, a central region 1922, and a lower region 1923 by an upper slit 1924 and a lower slit 1925. A portion of the upper slit 1924 extends toward the lower part of the cover 1920 (i.e., toward the opening 1926), and the upper slit 1924 may have a “T” shape. Symmetrically, a portion of the lower slit 1925 extends toward the upper part of the cover 1920, and the lower slit 1925 may also have a “T” shape. The upper region 1921 and the central region 1922 are electrically connected by a first connecting portion 1927, and the central region 1922 and the lower region 1923 are electrically connected by a second connecting portion 1928.

[0189] refer to Figure 19 Parts (b) and (c), loop antenna 1931 (e.g., Figures 11A to 11F A loop antenna 1120 is positioned between the upper slit 1924 and the lower slit 1925 and can generate a magnetic field along the X-axis. Therefore, the magnetic flux generated by the loop antenna 1931 can extend to the upper slit 1924 and the lower slit 1925 and be emitted to the outside of the electronic device. A battery can be arranged below the loop antenna 1931.

[0190] The length of the loop antenna 1931 can be less than the distance between the upper slit 1924 and the lower slit 1925. In this case, eddy currents or internal conductive components occurring in the cover 1920 can reduce the radiation efficiency below a desired level. The first metal plate 1932 and the second metal plate 1933 can be attached close to (or in contact with) opposite ends of the loop antenna 1931, respectively. This reduces eddy current generation, and magnetic flux can easily diffuse to the upper slit 1924 and the lower slit 1925. The first metal plate 1932 or the second metal plate 1933 can be used as a radiator for different communication schemes. For example, the loop antenna 1931 can operate together with the first metal plate 1932 and the second metal plate 1933 and act as a radiator for the MST. The first metal plate 1932 or the second metal plate 1933 can be used as a radiator for NFC or Wireless Charging (WPC). That is, the first metal plate 1932 and the second metal plate 1933 can be arranged close to the upper slit 1924 and the lower slit 1925 respectively, and the magnetic flux generated by the first metal plate 1932 or the second metal plate 1933 can be emitted to the outside through the upper slit 1924 or the lower slit 1925.

[0191] The metal plate in the loop antenna 1931 (e.g., Figures 11A to 11F The permeability of the core 1124b can be different from that of the first metal plate 1932 or the second metal plate 1933. The permeability of the first metal plate 1932 can also be different from that of the second metal plate 1933. For example, when the metal plates of the loop antenna 1931, the first metal plate 1932, and the second metal plate 1933 are used for MST, NFC, and WPC, respectively, they can have different operating frequencies (e.g., 13.56 MHz for NFC, 100 kHz to 205 kHz for WPC, and 100 kHz or lower for MST) and different permeabilities. Although the first metal plate 1932 and the second metal plate 1933 are used for different purposes, they can diffuse the magnetic flux generated by the loop antenna 1931 to the upper slit 1924 or the lower slit 1925, thereby enhancing the MST performance.

[0192] The area of ​​the cover 1920 below the lower slit 1925 can be used as an antenna. For example, the left portion to the left of the second connecting portion 1928 can be used as a first antenna 1941, and the right portion to the right of it can be used as a second antenna 1942. Both the first antenna 1941 and the second antenna 1942 can be electrically connected to the second substrate 1960. The first antenna 1941 and the second antenna 1942 can receive signals from the communication circuit and transmit the received signals, respectively, through the first feed point 1961 and the second feed point 1962 provided on the second substrate 1960, and can also receive radio signals from the outside and forward the received signals to the communication circuit through the first feed point 1961 and the second feed point 1962, respectively. The first antenna 1941 and the second antenna 1942 can be used as main antennas for signal transmission and reception. The operating frequency of the first antenna 1941 can be higher than the operating frequency of the second antenna 1942. For example, the first antenna 1941 can support 1.6 to 5 GHz, and the second antenna 1942 can support 600 MHz to 2 GHz.

[0193] The area above the upper slit 1924 of the cover 1920 can be used as an antenna. For example, the right side portion to the right of the first connecting portion 1927 can be used as a third antenna 1943, and the left side portion to the left of it can be used as a fourth antenna 1944. Both the third antenna 1943 and the fourth antenna 1944 can be electrically connected to the first substrate 1950. The third antenna 1943 and the fourth antenna 1944 can receive signals from the communication circuit and transmit the received signals, respectively, through the third feed point 1951 and the fourth feed point 1952 arranged on the first substrate 1950, and can also receive radio signals from the outside and forward the received signals to the communication circuit through the third feed point 1951 and the fourth feed point 1952, respectively. The third antenna 1943 and the fourth antenna 1944 can be used as diversity antennas for signal reception. The operating frequency of the third antenna 1943 can be higher than the operating frequency of the fourth antenna 1944. For example, the third antenna 1943 can support 1.6 to 5 GHz, and the fourth antenna 1944 can support 600 MHz to 2 GHz.

[0194] The first connecting portion 1927 and the second connecting portion 1928 can be arranged on the opposite side relative to the X-axis. A first antenna 1941 and a third antenna 1943 supporting similar frequencies are arranged diagonally opposite each other, and a second antenna 1942 and a fourth antenna 1944 supporting similar frequencies are also arranged diagonally opposite each other. This antenna arrangement can increase isolation between the antennas and reduce correlation in signal transmission and reception.

[0195] In the cover 1920, the central region 1922 between the slits can be electrically connected to the ground 1953 of the first substrate 1950. To prevent electric shock, the central region 1922 can be connected to the ground 1953 via a capacitor. The use of ground 1953 can enhance antenna performance and increase noise blocking effect.

[0196] The height of the first substrate 1950 may differ from the height of the second substrate 1960. The first substrate 1950 and the second substrate 1960 can be connected via an FPCB 1970. Since the second substrate 1960 is positioned lower than the first substrate 1950, the distance along the Z-axis between the second substrate 1960 and the first antenna 1941 or the second antenna 1942 can be greater than the distance between the first substrate 1950 and the first antenna 1941 or the second antenna 1942. A longer distance between the second substrate 1960 and the first antenna 1941 or the second antenna 1942 can enhance the performance of the first antenna 1941 and the second antenna 1942. The circuitry of the first substrate 1950 and the power supply module of the second substrate 1960 can be connected via a coaxial cable.

Figure 20 Part (a) shows the rear surface of the electronic device. Figure 20 Part (b) shows the internal components arranged below the rear surface. Figure 20 Section (c) together shows the rear surface and internal components.

[0198] refer to Figure 20 In part (a), the cover 2010 may constitute the rear surface of the electronic device and may be made of a conductive material. The cover 2010 is divided into an upper region 2013, a central region 2014, and a lower region 2015 by an upper slit 2011 and a lower slit 2012. The upper region 2013 and the central region 2014 are electrically connected by a first connecting part 2016, and the central region 2014 and the lower region 2015 are electrically connected by a second connecting part 2017.

Additionally, the right-side portion of the first connection portion 2016 is electrically connected to the feed coil 2045 via a fifth feed point 2034 formed on the first substrate 2030, and can be used as a different antenna (e.g., an NFC antenna). The upper end of the loop antenna 2051 (e.g., Figures 11A to 11F The loop antenna 2051 can extend to the upper slit 2011. Although the upper end of the loop antenna 2051 may not extend to the lower slit 2012, the metal plate 2052 can be arranged between the upper end and the lower slit 2012. Therefore, the magnetic flux generated by the loop antenna 2051 can diffuse to the lower slit 2012 through the metal plate 2052.

The fingerprint sensor 2130 can be electrically connected to the first substrate 2160 and / or the second substrate 2170, and can recognize fingerprints detected on the home button 2111a and generate and output fingerprint information. For example, the fingerprint sensor 2130 can output fingerprint data to a processor (e.g., an application processor) mounted on the first substrate 2160. The camera 2150 can be mounted on the first substrate 2160 and exposed through a hole 2112a formed in the rear cover 2112. The first substrate 2160 may be arranged adjacent to the upper cover 2116 of the side member 2120 and may be electrically connected to the upper cover 2116. The second substrate 2170 may be arranged adjacent to the lower cover 2115 and may be electrically connected to the lower cover 2115. The antenna 2190 may include a plurality of coil antennas for payment and may be electrically connected to the substrate (e.g., a communication module such as NFC control module 140 mounted on the first substrate 2160 or the second substrate 2170).

[0202] Display 2193 may include liquid crystal or organic light-emitting diodes (OLEDs) and signal lines arranged along the X-axis for driving them. A loop antenna 2195 may be attached to the bottom surface of display 2193. The loop antenna 2195 may include a solenoid coil. Signal coupling may occur when the current path of the solenoid coil is in the same direction as the arranged signal lines. That is, electrical coupling may occur between the solenoid coil and the signal lines when current flows through it. This signal coupling may cause driving errors in display 2193. To prevent signal coupling, it is assumed that the configuration of the loop antenna 2195 is, for example... Figures 11A to 11F The configuration is the same as that of the loop antenna 1120.

[0205] Housing 2210 protects various components arranged therein (e.g., display 2220, battery 2224, substrate 2230, and loop antenna 2250). Housing 2210 includes a bezel wheel 2210a arranged around an opening 2211 through which the display 2220 is exposed. The bezel wheel 2210a prevents the boundary area of ​​the display 2220 from being exposed outward and can generate user input by rotation.

[0206] Display 2220 may be in the form of a disk of a given width and may be used to output image or text data. When display 2220 includes a touch panel, it may receive user touch input and forward the touch input to a processor mounted on substrate 2230. A ground portion of display 2220 (e.g., FPCB, shielding layer, or heat dissipation layer) may be connected to the ground portion of substrate 2230 to maintain antenna performance. A tail-shaped ground pattern may be pulled out from the ground portion of display 2220. The tail-shaped ground pattern may be housed in bracket 2222 and may be electrically connected to a surface of substrate 2230. The electrical connection between the ground portion of display 2220 and the ground portion of substrate 2230 may prevent display 2220 from interfering with the transmission and reception of signals. Display 2220 may have a layered structure including a touch panel, a display panel, an adhesive layer, a ground layer, and an FPCB. Display 2220 may include signal lines for exchanging data with substrate 2230.

[0207] Display 2220 is exposed outward through opening 2211, and loop antenna 2230 is disposed below display 2220. Loop antenna 2230 is electrically connected to a communication module (e.g., MST control module 130) mounted on substrate 2230. Assuming the signal lines of display 2193 are arranged along the X-axis, the configuration of loop antenna 2250 is similar to... Figures 11A to 11F If the configuration of the loop antenna 1120 is the same, then the direction of the current in the solenoid coil of the loop antenna 2250 can be the Y-axis direction, which is perpendicular to the X-axis direction of the arranged signal line.

[0208] The bracket 2222 is used to mount or secure the display 2220, the battery 2224, and the substrate 2230. The bracket 2222 can also be used to mount or secure signal lines that interconnect the various components. The bracket 2222 can be made of a non-conductive material (e.g., plastic).

The substrate 2230 may include a feed portion for powering an antenna radiator and a ground portion. The ground portion may be connected to the housing 2210. In this case, the housing 2210 can serve as an antenna radiator and can be electrically connected to the RF module of the substrate 2230. The ground portion of the substrate 2230 is connected to the ground portion of the display 2220 (e.g., an FPCB, shielding layer, or heat dissipation layer). The ground portion of the substrate 2230 may also be connected to the housing 2210. The rear cover 2240 is coupled to the housing 2210 to secure and protect internal components. The rear cover 2240 may be made of a non-metallic or non-conductive material. Alternatively, the rear cover 2240 may be made of a conductive material and can be electrically insulated from the housing 2210 by a separate insulating member. The rear cover 2240 may include at least one slit. For example, the first slit and the second slit can be formed as opposite ends 2252 and 2251 of the loop antenna 2250 on the rear cover 2240, respectively.

Therefore, the electronic device 2300 can be unfolded, allowing the first display 2331 and the second display 2332 to... Figure 23A The displays shown face the same direction, or can be folded so that the first display 2331 and the second display 2332 are as follows: Figure 23B The objects are shown facing each other.

Tokens can be created using the Bank Identification Number (BIN), etc. The created token can be encoded by the TSP 2630. Alternatively, the created token can be transmitted to the payment service server 2620 without encoding, and then encoded by the payment service server 2620. The encoded token is then sent to the electronic device 2610 via the payment service server 2620. The electronic device 2610 decodes the encoded token. In embodiments of this disclosure, a token is created and encoded in the TSP 2630, and the processed token is sent to the electronic device 2610 without going through the payment service server 2620. The payment service server 2620 may be equipped with a token creation function. In this case, the payment system 2600 can be implemented without the TSP 2630.

[0272] When electronic device 2610 is functionally connected to other electronic devices 2650 and 2660 via short-range wireless communication (e.g., BT or Wi-Fi), electronic device 2610 is able to make payments using at least one of the other electronic devices 2650 and 2660. An example of the other electronic device 2650 (e.g., a third external device) is a wearable device (e.g., a smartwatch). In this case, electronic device 2610 can cooperate with the wearable device to make payments. For example, electronic device 2610 can send a card image to the smartwatch. The smartwatch can send a payment command signal in response to the transmission of the card image to electronic device 2610. Electronic device 2610 receives the payment command signal and transmits an MST signal. An example of the other electronic device 2660 (e.g., a fourth external device) is an accessory (e.g., LoopPay). TM In this case, electronic device 2610 is functionally connected to the accessory via an input / output interface (e.g., headphones).

[0273] Figure 27 This is a diagram illustrating a method of interacting with a payment UI on an electronic device according to an embodiment of the present disclosure.

[0274] refer to Figure 27 Electronic devices 2710 (e.g., Figure 1A The electronic device 11 shown receives user input and runs a payment application. For example, the electronic device 2710 may run a payment application (e.g., Samsung Pay) in response to user input 2730 (e.g., swiping a card towards the display 2720 on the bezel area 2610). Alternatively, the electronic device 2710 may display a card image 2740 corresponding to at least one card registered therein on the display 2720 in response to user input 2730.

[0275] Electronic device 2710 is capable of selecting one of multiple registered cards as the payment card for payment in response to user input. For example, electronic device 2710 selects a card for payment in response to user input 2750 (e.g., side scrolling) and displays the corresponding card image 2760. Electronic device 2710 may request user authentication to use the selected card for payment. Authentication can be performed using the user's biometric information. For example, electronic device 2710 scans the user's fingerprint 2770 via a fingerprint detection module for payment. When the user has been authenticated by the fingerprint detection module, electronic device 2710 can perform transmission in a simple transmission sequence (e.g., sending an MST signal containing orbital information a certain number of times).

[0276] User authentication can be re-executed to re-execute the payment process. For example, when user authentication is terminated due to the expiration of a specific time period, electronic device 2710 can change the current method and retransmit the MST signal. For example, electronic device 2710 can change the transmission period or pulse timing. Alternatively, electronic device 2710 can change the information contained in the MST signal to information according to a composite transmission sequence. In embodiments of this disclosure, to re-execute the payment operation, the user can separate electronic device 2710 from the terminal and then re-tag it to the terminal. The user's tagging operation can be detected by various types of sensors installed on electronic device 2710 (e.g., accelerometer 103, gyroscope 105, proximity sensor, heart rate monitor (HRM) sensor, etc.). In response to the tagging operation, electronic device 2710 changes the MST signal according to at least one of the following transmission period, pulse timing, and sequence, and transmits the changed MST signal. Each time the user performs a tagging operation, electronic device 2710 changes the MST signal according to at least one of the following transmission period, pulse timing, and sequence, and transmits the changed MST signal.

[0277] Once user authentication is complete, electronic device 2710 can send NFC and MST signals simultaneously or sequentially. For example, the processor of the electronic device (e.g., Figure 1B The processor 150) controls the NFC control module (e.g., Figure 1B 140) and MST control module (e.g., Figure 1B (130) to activate the NFC module (e.g., Figure 1B (e.g., the NFC module is set to polling mode) to detect the card reader, and simultaneously via the MST module (e.g., Figure 1BThe processor (110) creates an MST signal. It determines whether it has received a signal from the card reader via the NFC module (e.g., ping). When the processor determines it has received a signal, it stops the operation of the MST module. The processor can provide information about the card to make a payment to the card reader (e.g., an NFC reader) via the NFC module. Conversely, when the processor determines it has not received a signal, it controls the MST control module to create an MST signal containing payment information.

[0278] When payment is complete, the user presses a button on the electronic device (e.g., the home button 2780) to end the payment application. Alternatively, when payment is complete, the electronic device 2710 (UE) detects the payment completion and stops creating an MST signal. For example, when the card issuer has determined that the payment is complete, it notifies the UE of the payment result via the network, thereby stopping the UE from creating an MST signal. Besides the card issuer, the payment result can also be sent to the UE via a value-added service network (VAN), a POS terminal, etc.

[0279] Figure 28 This is a diagram illustrating a method of interacting with a payment UI on an electronic device according to an embodiment of the present disclosure.

[0280] refer to Figure 28 While the payment is in progress after user authentication, the electronic device can display a payment status (or the status of payment information being transmitted from the electronic device to an external device). For example, the electronic device displays a semi-transparent circle 2820 behind the card image 2810 on the screen, and displays an effect 2840 as the size of the circle in frame 2830 increases. Frame 2830 may correspond to the position of a loop antenna transmitting the MST signal. The antenna position can be identified by referring to frame 2830. When the size of the circle within frame 2830 increases, the user can recognize that payment is in progress, as shown in effect 2840.

[0281] Figure 29 This is a diagram illustrating the configuration of an electronic device having an antenna and antenna structure for magnetic payment according to an embodiment of the present disclosure.

[0282] refer to Figure 29The electronic device 2900 includes an upper housing 2910, a lower housing 2920, and a side housing 2940 (positioned to expose at least a portion of the appearance of the electronic device 2900), and an internal support 2930 located inside the handheld electronic device. The side housing 2940 is made of a single material or a mixture of dissimilar materials. The side housing 2940 may be arranged to support at least a portion of the upper housing 2910 and the lower housing 2920. The internal support 2930 is made of a single material or a mixture of dissimilar materials. The internal support 2930 may be arranged to support at least a portion of the lower housing 2920. At least a portion of the upper housing 2910 and the lower housing 2920 may include a display area. For example, a display module (e.g., ...) may be exposed through a portion of the upper housing 2910. Figure 1A The display module 16). The upper housing 2910, the side housing 2940, and the support member 2930 form a enclosure. The enclosure can include a PCB 2950 and a battery 2970.

[0283] Electronic device 2900 includes an antenna (e.g., a coil antenna) 2960 for magnetic payment. Antenna 2960 covers at least a portion of a side housing 2940 and a battery 2970. Antenna 2960 is connected to a PCB 2950 through an opening in the side housing 2940 for communication with a communication module (e.g., [missing information]). Figure 1B The MST control module 130 shown in the diagram) or the processor located on the PCB 2950 (e.g., Figure 1B The processor 150 shown performs data communication for payment. The side housing 2940 and the upper housing 2910 may be formed such that the height or thickness of a portion of the area to which the antenna 2970 is attached differs from the surrounding area.

[0284] The side housing 2940 may be formed such that the area where the coil (e.g., a metal pattern) of the antenna 2960 is located is made of a different material than another area where the coil is not present. For example, the area where the coil of the antenna 2960 is located may include a non-conductive material (e.g., plastic). The area where the coil of the antenna 2960 is not present may include a conductive material (e.g., metal).

[0285] refer to Figure 29(c) The antenna 2960 is formed using an FPCB comprising multiple layers 2963 to 2965. At least one of the multiple layers 2963 to 2965 includes a through-hole 2967 and a conductor 2966 forming an antenna coil. The antenna 2960 may be configured with a single coil. The antenna 2960 may also be configured with two or more coils that are different from each other. The antenna 2960 includes a layer 2961 for shielding noise. The shielding layer 2961 may be formed of a material such as graphite. The antenna 2960 also includes a magnet layer 2962 for increasing the strength of the magnetic field signal generated by the coil. The magnet layer 2962 may be formed of a permanent magnet, a ferromagnetic material, etc.

[0286] A fingerprint sensor used to authenticate payment cards or users may be included in a home button on the front, a button on the side, or a button on the back of an electronic device. Alternatively, the fingerprint sensor may be included in at least a portion of the display panel.

[0287] Figure 30A and Figure 30B This is a diagram illustrating the configuration of an MST module with one antenna according to an embodiment of the present disclosure.

[0288] refer to Figure 30A and Figure 30B The MST module (e.g., MST module 110) includes a driver section 3010, a connection section 3020, and an antenna 3030. The connection section 3020 can draw current from the driver section 3010 and feed the current to the antenna 3030. The antenna 3030 can generate a magnetic field based on the fed current and transmit a magnetic field signal with a given frequency (MST signal) to the outside. For example, the antenna 3030 can receive signals from the driver section 3010 via the connection section 3020, such as... Figure 7 The sequence shown is converted into RF signals and then sent sequentially.

[0289] Antenna 3030 can be designed to generate a magnetic field whose intensity varies with a certain factor. For example, as... Figure 30A As shown, when current is fed to antenna 3030, the first portion 3031 and the second portion 3032 can generate magnetic fields of different intensities. The first portion 3031 and the second portion 3032 can be composed of the same type of coil antenna. For example, the first portion 3031 and the second portion 3032 can be constructed from a flat loop antenna (e.g., antenna 1020) or a solenoid loop antenna (e.g., antenna 1120). The first portion 3031 and the second portion 3032 can also be constructed from different types of coil antennas. For example, one of the first portion 3031 and the second portion 3032 can be constructed from a flat loop antenna 1020, while the other can be constructed from a solenoid loop antenna 1120.

[0290] Antenna 3030 can be designed to generate different current paths depending on the portion. For example, as Figure 30B As shown, when current is fed to antenna 3030, antenna 3030 can generate a first path 3033 in the first part and a second path 3036 in the second part. Here, the first part and the second part can be constructed from the same type of coil antenna. For example, the first part and the second part can be constructed from a flat loop antenna 1020 or a solenoid loop antenna 1120. The first part and the second part can also be constructed from different types of coil antennas. For example, one of the first part and the second part can be constructed from a flat loop antenna, while the other can be constructed from a solenoid loop antenna.

[0291] Figure 31A and Figure 31B This is a diagram illustrating the configuration of an MST module with two loop antennas according to an embodiment of the present disclosure.

[0292] refer to Figure 31A and Figure 31B The MST module (e.g., MST module 110) includes a driver portion 3110, a connection portion 3120, a first antenna 3130, and a second antenna 3140. The first antenna 3130 and the second antenna 3140 can be of different types. For example, one of the two antennas can be a flat antenna (e.g., a first loop antenna 1020), while the other antenna can be a solenoid antenna (e.g., a second loop antenna 1120). When the MST module includes a solenoid antenna, the MST module can be protected by a housing (e.g., a housing with a cover 1113) made of at least a portion of a non-conductive material.

[0293] In embodiments of this disclosure, the first antenna 3130 and the second antenna 3140 can transmit the same MST signal. (See reference...) Figure 31A The driving section 3110 forms a first electrode 3111 and a second electrode 3112. The connecting section 3120 electrically connects the first electrode 3111 to the first antenna 3130 and the second antenna 3140, and electrically connects the second electrode 3112 to the first antenna 3130 and the second antenna 3140. The first antenna 3130 and the second antenna 3140 receive current from the first electrode 3111 or the second electrode 3112 via the connecting section 3120, generate a magnetic field through the received current, and respectively transmit magnetic field signals (MST signals) of a specific frequency. For example, the first antenna 3130 and the second antenna 3140 receive current from the driving section 3110 via the connecting section 3120. Figure 7 The sequence shown converts the sequence into RF signals and sequentially transmits the RF signals to the outside.

[0294] The first antenna 3130 and the second antenna 3140 can transmit different MST signals respectively. (Reference) Figure 31B The driving section 3110 forms one pair of electrodes (third electrode 3113 and fourth electrode 3114) and another pair of electrodes (fifth electrode 3115 and sixth electrode 3116). The connecting section 3120 electrically connects the third electrode 3113 and the fourth electrode 3114 to the first antenna 3130, and electrically connects the fifth electrode 3115 and the sixth electrode 3115 to the second antenna 3140. The first antenna 3130 receives current from the third electrode 3113 or the fourth electrode 3114 via the connecting section 3120, generates a magnetic field through the received current, and transmits an RF signal of a specific frequency to the outside. Similarly, the second antenna 3140 receives current from the fifth electrode 3115 or the sixth electrode 3115 via the connecting section 3120, generates a magnetic field through the received current, and transmits an MST signal of another frequency to the outside. For example, Figure 7 The sequences shown can be transmitted in the following order: a first simple transmission sequence 710 transmitted via the first antenna 3130, a first composite transmission sequence 720 transmitted via the second antenna 3140, a second simple transmission sequence 730 transmitted via the first antenna 3130, and a second composite transmission sequence 740 transmitted via the second antenna 3140. Alternatively, Figure 7 The sequences shown can be transmitted in the following order: a first simple transmission sequence 710 and a second composite transmission sequence 720 are transmitted sequentially through a first antenna 3130, and a second simple transmission sequence 730 and a second composite transmission sequence 740 are transmitted sequentially through a second antenna 3140.

[0295] Figure 32 This is a diagram illustrating a loop antenna according to an embodiment of the present disclosure.

[0296] refer to Figure 32 The loop antenna 3200 can be designed to generate magnetic fields of varying strengths from one part to another. This indicates that the null point of the loop antenna 3200 can be formed at different locations depending on the part within the electronic device. For example, as... Figure 32As shown, the antenna pattern (e.g., a coil) of the first portion 3210 is implemented with a width greater than that of the antenna pattern of the second portion 3220. In this case, the first portion 3210 through which current flows has a smaller resistance than the second portion 3220. Therefore, the first portion 3210 generates a higher magnetic field strength than the second portion 3220. In this case, the null point of the loop antenna 3200 can be formed in the bottom 3240 of the electronic device, rather than in the center portion 3230. For example, when the width of the antenna pattern of the first portion 3210 is the same as the width of the antenna pattern of the second portion 3220, the null point can be formed in the center portion 3230 of the electronic device. When the width of the antenna pattern of the first portion 3210 is greater than the width of the antenna pattern of the second portion 3220, the null point can be formed in the bottom 3240 of the electronic device. For example, as Figure 42 As shown, when a payment is in progress, electronic devices (e.g., such as...) Figure 1B The illustrated electronic device 100 displays the MST recognition range on the screen (e.g., the area between the center and top of the electronic device corresponding to box 4230), which allows the user to easily identify the MST recognition range and move the electronic device near the reader. Therefore, the loop antenna system improves the MST recognition rate of the electronic device.

[0297] Figures 33A to 33G This is a diagram illustrating the structure of a loop antenna according to an embodiment of the present disclosure.

[0298] refer to Figures 33A to 33G ,like Figure 33A As shown, the loop antenna 3310 is designed such that a first path 3311 is formed at the top of the electronic device (e.g., a smartphone), a second path 3312 is located at the center, and a third path 3313 is located at the bottom. Furthermore, the direction of the current 3311a flowing in the first path 3311 is the same as the direction of the current 3312a flowing in the second path 3312. In this case, the current direction 3311a in the first path 3311 is opposite to the direction of the current 3313a flowing in the third path 3313. When the loop antenna 3310 receives power from the communication module 3315 (e.g., ...), ... Figure 1B When the current of the MST module 110 shown generates a magnetic field, the magnetic field strength at the center and bottom is greater than that at the bottom, so zero point 3314 is formed near the bottom of the electronic device.

[0299] refer to Figure 33BThe loop antenna 3320 is designed such that the direction of the current 3323a flowing in the third path 3323 is the same as the direction of the current 3322a flowing in the second path 3322. In this case, the current directions 3323a and 3322a are opposite to the direction of the current 3321a flowing through the first path 3321. Therefore, a zero point 3325 is formed near the top of the electronic device.

[0300] refer to Figure 33C The path of the loop antenna 3330 connected to the communication module 3332 (e.g., the MST module) is shaped like the letter "B" (i.e., the current flows in the path like the letter "B"), wherein the currents flowing in the path in the central portion 3331 are in opposite directions. Therefore, the central portion 3331 is a zero point. Figure 32 Compared to the loop antenna 3200 shown, the loop antenna 3330, shaped like the letter "B", results in the effect of distributing the null point to both sides (top and bottom).

[0301] refer to Figure 33D The path of the loop antenna 3340 connected to the communication module 3342 (e.g., the MST module) is shaped like the number "8", with the current flowing in the path in the central portion 3341 in the same direction. Therefore, the magnetic field strength is greatest in the central portion 3341. Null points are formed in the top 3343 and bottom 3344.

[0302] Furthermore, loop antennas can be designed with paths of various shapes, such as a path shaped like the letter "B," as shown below. Figures 33E to 33G As shown in the attached figure. In the figure, the arrows indicate the direction of the current, and the portions 3350, 3360, and 3370 where the current directions are opposite to each other are zero points.

[0303] As referenced above Figures 33A to 33G As mentioned above, the null point of a loop antenna varies depending on the location of the path (current path) and the direction of the current. Therefore, when an antenna is designed to increase the MST recognition rate, the location of the null point needs to be considered.

[0304] Figure 34A and Figure 34B This is a diagram illustrating the structure of a loop antenna according to an embodiment of the present disclosure.

[0305] refer to Figure 34A and Figure 34B It can Figure 34A The loop antenna 3410 shown is applied to Figure 16BAntenna 1630 is shown in the diagram. The loop antenna 3410 is implemented such that the first path 3411 forming the exterior is a flat coil, and the second path 3412 forming the interior is a solenoid coil. For example, the flat coil can be a coil wound without overlap in the XY plane. The solenoid coil can be a coil wound multiple times relative to the Z-axis. Figure 34B As shown, the solenoid coil can be a coil wound multiple times on an axis perpendicular to the Z-axis. As the number of turns of the coil arranged in each section and the area where the coil is arranged change, the null point moves from the center of the loop antenna to the outside, thereby transmitting a relatively large amount of magnetic flux from the second path 3412.

[0306] Figure 35A and Figure 35B This is a diagram illustrating the structure of a plurality of loop antennas according to embodiments of the present disclosure.

[0307] refer to Figure 35A and Figure 35B Multiple loop antennas (e.g., first antenna 3511 and second antenna 3512) are connected to the same output section of the MST control module. First antenna 3511 and second antenna 3512 can transmit the same signal simultaneously. For example, as... Figure 35A As shown, one end of each of the first antenna 3511 and the second antenna 3512 is connected to the first electrode 3521, and the other end of each of the first antenna 3511 and the second antenna 3512 is connected to the second electrode 3522. The first antenna 3511 and the second antenna 3512 can be configured on different layers of the FPCB. For example, relative to the Z-axis, the first antenna 3511 and the second antenna 3512 are formed on the bottom and top layers of the FPCB, respectively. Alternatively, a loop antenna can also be formed on the same layer. For example, as... Figure 35B As shown, the first antenna 3531 and the second antenna 3532 can be formed on the top 3541 and bottom 3542 of the XY plane, respectively.

[0308] Figure 36A and Figure 36B This is a diagram illustrating the structure of a plurality of coil antennas according to embodiments of the present disclosure.

[0309] refer to Figure 36A Multiple coil antennas (e.g., first antenna 3611 and second antenna 3612) are formed on the same plane (e.g., the XY plane). The loop antenna (or MST loop antenna) for the MST can be implemented in various forms to improve the identification of magnetic fields emitted to external devices (e.g., POS terminals). For example, the path of the coil antenna can be implemented as follows: Figure 33C The shape of the letter "B" shown in the image, or Figure 33DThe number "8" is shown in the diagram. The coil antenna can be implemented in such a way that, when the electronic device moves near the POS terminal, a path (current path) is formed to the maximum extent possible, perpendicular to the direction of swiping the magnetic card on the POS terminal. The first antenna 3611 and the second antenna 3612 can transmit different MST signals. For example, the first antenna 3611 (e.g., Figure 45B The first antenna 4530 shown can transmit. Figure 7 A portion of the sequence shown. Similarly, the second line 3612 (e.g., Figure 45B The second antenna 4540 shown can transmit. Figure 7 Another part of the sequence shown in the image.

[0310] refer to Figure 36B Coil antennas can be formed on different planes relative to different axes. For example, the first coil antenna 3621 and the second coil antenna 3622 can form loops relative to the X-axis and Y-axis, respectively. Shielding material can be arranged between the first coil antenna 3621 and the second coil antenna 3622 to prevent interference between them.

[0311] The first coil antenna 3621 or the second coil antenna 3622 can be an FPCB antenna. Multiple layers of the FPCB are connected to a pattern to form a layered ring.

[0312] The first coil antenna 3621 or the second coil antenna 3622 can form a loop that wraps around at least a portion of the housing of the electronic device. The coil antenna can be implemented such that one portion is located below the front display of the electronic device and the other portion is located below the rear of the electronic device. The coil antenna can be implemented using an FPCB or utilize at least a portion of the external body of the electronic device.

[0313] Figure 37 , Figure 38 and Figure 39 This is a block diagram illustrating an electronic device including a plurality of MST modules according to an embodiment of the present disclosure.

[0314] refer to Figure 37The first MST module 3710 and the second MST module 3720 are capable of transmitting the same data to an external device. The first MST module can include a coil antenna of a different type than that of the second MST module 3720. The first MST module 3710 and the second MST module 3720 are separate from each other. The first MST module 3710 and the second MST module 3720 can receive different voltage levels or different current amounts, respectively. The MST control module 3730 includes a first data receiving module 3731 and a second data receiving module 3732, which are capable of receiving at least one identical signal from the MST data transmission module 3740. For example, the MST data transmission module 3740 can transmit data containing the same payment information (e.g., ...). Figure 45A and Figure 45B The MST signal 3751 (shown in the diagram) is sent to the first data receiving module 3731 and the second data receiving module 3732 of the MST control module 3730. Additionally, the MST data transmission module 3740 can send a control signal 3752, used to activate the first MST module 3710 and the second MST module 3720, to the first data receiving module 3731 and the second data receiving module 3732. The MST control module 3730 receives the control signal 3752 and controls the first MST module 3710 and the second MST module 3720 to transmit the MST signal 3751 to the outside. The first data receiving module 3731 and the first output conversion module can be configured as a signal module. The second data receiving module 3732 and the second output conversion module can also be configured as a signal module.

[0315] refer to Figure 38 The MST data transmission module 3840 will contain the same payment information (e.g., Figure 7 The MST signal A (as shown in the sequence) is sent to the first data receiving module 3831 and the second data receiving module 3832. The MST data transmission module 3840 also sends control signals B and C to the first data receiving module 3831 and the second data receiving module 3832 to independently control the first MST module 3810 and the second MST module 3820, respectively. The first MST module 3810 and the second MST module 3820 are activated sequentially according to the respective control signals and transmit a portion of a separate MST signal. For example, the first MST module 3810 is activated first and the sequence is transmitted sequentially (e.g., in the order of sequences 710 and 720). The second MST module 3820 is activated and the sequence is transmitted sequentially (e.g., in the order of sequences 730 and 740).

[0316] The first MST module 3810 and the second MST module 3820 can be activated alternately to transmit MST signals to an external device (e.g., a POS terminal). For example, the first MST module 3810 can be activated first to transmit a sequence (e.g., sequence 710), and then the second MST module 3820 can be activated to transmit a sequence (e.g., sequence 720). The first MST module 3810 can be activated again to transmit a sequence (e.g., sequence 730), and then the second MST module 3820 can be activated again to transmit a sequence (e.g., sequence 740).

[0317] The first MST module 3810 and the second MST module 3820 can be selectively activated based on the UE's state. For example, when the UE activates short-range wireless communication (e.g., NFC communication) using a loop antenna near the first MST module 3810, or when the UE activates cellular network wireless communication using an adjacent antenna, the MST control module 3830 activates the second MST module 3810 to transmit an MST signal. For example, when the UE activates the first MST module 3810 and / or the second MST module 3820 and uses the activated module to transmit an MST signal to an external device (e.g., a POS terminal), the external device may not be able to recognize the MST signal. In this case, the user can move the UE so that it can be recognized by the external device (e.g., the user can remove the UE from the POS terminal and then attach it to it). The UE enables a sensor to detect this operation, thereby activating both the first MST module 3810 and the second MST module 3820 simultaneously. For example, when the screen is displayed in portrait mode, the UE can activate the second MST module 3820 (e.g., Figure 36B The second coil antenna 3622 shown in the figure), and when the screen is displayed in landscape mode, the UE can activate the first MST module 3810 (e.g., Figure 36B The first coil antenna 3621 is shown in the figure.

[0318] The MST data transmission module 3840 sends a control signal D, used to activate the first MST module 3810 and the second MST module 3820, to the first data receiving module 3831 and the second data receiving module 3832, respectively. The MST data transmission module 3840 also sends MST signals E and F, containing different payment information, to the first data receiving module 3831 and the second data receiving module 3832, respectively. For example, the MST data transmission module 3840 can send MST signals containing track 1 information and track 2 information to the first data receiving module 3831 and the second data receiving module 3832, respectively. The MST signal containing track 1 information is sent to the first MST module 3810 via the first output conversion module 3851. The first MST module 3810 transmits the received MST signal. Similarly, the MST signal containing track 2 information is sent to the second MST module 3820 via the second output conversion module 3852. The second MST module 3820 transmits the received MST signal. The first data receiving module 3831 and the first output conversion module 3851 can be configured as a signal module. The second data receiving module 3832 and the second output conversion module 3852 can be configured as a signal module.

[0319] refer to Figure 39 The MST data transmission module 3940 can send MST signals 3951 and 3952, containing different payment information, to the first data receiving module 3931 and the second data receiving module 3932 of the MST control module 3930, respectively. For example, the MST data transmission module 3940 can send sequences 710 and 720 to the first data receiving module 3931 and sequences 730 and 740 to the second data receiving module 3932. Additionally, the MST data transmission module 3940 sends different control signals 3953 and 3954 to the MST control module 3930 to independently control the first MST module 3910 and the second MST module 3920. For example, after receiving control signals 3953 and 3954, the MST control module 3930 controls the first MST module 3910 to sequentially transmit sequences 710 and 720 to the outside, and then controls the second MST module 3920 to sequentially transmit sequences 730 and 740 to the outside. The first data receiving module 3931 and the first output conversion module can be configured as a signal module. The second data receiving module 3932 and the second output conversion module can also be configured as a signal module.

[0320] Figure 40 , Figure 41 and Figure 42 This is a block diagram illustrating an electronic device according to an embodiment of the present disclosure capable of sharing at least one of a plurality of MST modules with another short-range wireless communication.

[0321] refer to Figure 40The MST control module 4010 includes a switching unit 4050. The switching unit 4050 interrupts (disconnects) the connection between the second MST module 4020 and the MST control module 4010, allowing the second MST module 4020 to connect to the wireless charging control module 4030 and function as a wireless charging module (or wireless charging coil antenna). The wireless charging control module 4030 may also include an AC / DC converter, rectifier, etc. The power control module 4040 may be included in the electronic device. The second MST module 4020 may include a coil antenna with an inductance of approximately 10 μH.

[0322] refer to Figure 41 The electronic device can use at least one of a plurality of MST modules (e.g., the second MST module 4120) as a resonant coil antenna for wireless charging. The MST / wireless charging control module 4110 can include an MST control module 4111 and a wireless charging control module 4114. The MST control module 4111 includes a data receiving module 4112 and an output conversion module 4113.

[0323] refer to Figure 42 The electronic device can use at least one of a plurality of MST modules (e.g., the second MST module 4220) as an NFC coil antenna. When the second MST module 4220 is used as an NFC coil antenna, the electronic device may also include a switching unit 4230 to adjust the number of turns or inductance in the coil antenna. When the electronic device uses at least one of the MST modules (e.g., the second MST module 4220) as an MST module for other short-range wireless communication (e.g., NFC communication), the MST control module 4210 may also include a switch for disconnecting from the MST module (i.e., the second MST module 4220) used for other short-range wireless communication.

[0324] Figure 43 This is a diagram illustrating an antenna device according to an embodiment of the present disclosure.

[0325] refer to Figure 43 Antenna device 4300 is installed in electronic equipment. Antenna device 4300 includes a first loop antenna 4310 and a second loop antenna 4320, a communication module 4330 and a switch 4340. Communication module 4330 includes a first communication module 4331, a second communication module 4332 and a third communication module 4333, and four contacts 4334 to 4337.

[0326] The first communication module 4331 is electrically connected to the first loop antenna 4310 via a first contact 4334 and a second contact 4335, and performs the transmission / reception of electromagnetic waves for short-range wireless communication. For example, the first communication module 4331 is a resonant charging module (e.g., an Alliance for Wireless Power (A4WP)) and receives electromagnetic waves for charging via the first loop antenna 4310.

[0327] The second communication module 4332 is electrically connected to the second loop antenna 4320 via the third contact 4336 and the fourth contact 4337, and performs the transmission / reception of electromagnetic waves for short-range wireless communication. For example, the second communication module 4332 is used as an NFC module.

[0328] The third communication module 4333 is electrically connected to the first loop antenna 4310 and the second loop antenna 4320 via contacts 4334 to 4337 and switch 4340, and performs the transmission / reception of electromagnetic waves for short-range wireless communication (e.g., Wireless Power Union (WPC) or MST). For example, when switch 4340 is turned on, current flows along the following path: third communication module 4333, first contact 4334, first loop antenna 4310, second contact 4335, switch 4340, third contact 4336, second loop antenna 4320, fourth contact 4337, and third communication module 4333. For example, the first loop antenna 4310 and the second loop antenna 4320 form a path through switch 4340. Therefore, the third communication module 4333 performs the transmission / reception of electromagnetic waves via this path.

[0329] The operation (on / off) of switch 4330 is controlled by communication module 4340 or the control module of electronic device (e.g., application processor (AP)). Although Figure 43 The embodiment shown is implemented with switch 4330 included in communication module 4330, but it should be understood that this disclosure is not limited thereto. For example, switch 4330 can be installed in any location only if switch 4330 can connect the first loop antenna 4310 and the second loop antenna 4320 to each other. Alternatively, the location where switch 4330 will be installed can be determined by taking into account the length of the path, the number of turns in the path, the inductance of the path, etc., so that a specific frequency of the third communication module 4333 can be selected as the resonant frequency.

[0330] Figure 44 This is a diagram illustrating a plurality of coil antennas in an electronic device according to an embodiment of the present disclosure, and showing the null points and magnetic field strengths generated in the plurality of coil antennas.

[0331] refer to Figure 44(a) The electronic device 4410 may include a first coil antenna 4411 and a second coil antenna 4412. The first coil antenna 4411 and the second coil antenna 4412 generate a magnetic field according to the received current.

[0332] Figure 44 The diagram above (b) shows the magnetic field strength and null point generated and present due to the first coil antenna 4411 (or identified by an external device, such as a POS terminal). Figure 44 The figure below (b) shows the magnetic field strength and null point generated and present due to the second coil antenna 4412.

[0333] refer to Figure 44 (b) The first zero point 4421, which occurs due to the first coil antenna 4411, and the second zero point 4422, which occurs due to the second coil antenna 4412, may not overlap. The first coil antenna 4411 and the second coil antenna 4412 may periodically or alternately transmit the MST signal. For example, the first coil antenna 4411 and the second coil antenna 4412 may transmit the MST signal to the outside a total of 16 times (i.e., 8 times per antenna), with each transmission lasting one second. Thus, the zero points appear periodically and alternately, for example, from the first zero point 4421 to the second zero point 4422, or vice versa. When an external device (e.g., a POS terminal) is located at the first zero point 4421, it may not receive payment information from the first coil antenna 4411. Although the external device receives payment information, it may not be able to recognize the received payment information. In this case, the POS terminal receives the MST signal containing the payment information from the second coil antenna 4412 and makes the payment. As described above, the electronic device 4410 can drive multiple coil antennas so that zero points appear alternately or sequentially, thereby increasing the success rate of payment.

[0334] Figure 45A This is a diagram illustrating a plurality of coil antennas in an electronic device according to an embodiment of the present disclosure. Figure 45B This is a diagram illustrating the zero points and magnetic field strengths created in a plurality of coil antennas according to embodiments of the present disclosure.

[0335] refer to Figure 45A and Figure 45B The first coil antenna 4511 and the second coil antenna 4512 can operate simultaneously to transmit MST signals. For example... Figure 45A and Figure 45B As shown, the first coil antenna 4511 and the second coil antenna 4512 are respectively installed in the left and right regions of an electronic device (e.g., a smartphone).

[0336] refer to Figure 45AThe first coil antenna 4511 and the second coil antenna 4512 can simultaneously receive current, but the current directions are opposite to each other. For example, the first coil antenna 4511 forms a clockwise path, while the second coil antenna 4512 forms a counterclockwise path. In this case, the current directions are the same in the central part, which results in the maximum magnetic field strength. This condition also results in zeros around the central part, for example, two zeros 4513 and 4514 on either side of the central part.

[0337] refer to Figure 45B The current flows in the first coil antenna 4511 and the second coil antenna 4512 in the same direction. In this case, the current directions are opposite to each other in the central part, which results in a minimum magnetic field strength. This condition also results in a null point 4515 in the region between the two antennas (i.e., the central part).

[0338] As described above, since an electronic device with multiple coil antennas operates its coil antennas simultaneously, it can also periodically change the zero point by changing the direction of the current within them (e.g., making the current directions the same or opposite). For example, by operating multiple coil antennas simultaneously and changing the direction of the current within them, the electronic device alternately creates zero points, thereby increasing the success rate of payment.

[0339] Electronic devices can sequentially operate multiple coil antennas, as described above. Figure 44 (a) and Figure 44 As described in (b). Alternatively, the electronic device can simultaneously operate multiple coil antennas to change the direction of current, as described above. Figure 45A and Figure 45B As described above. Alternatively, the electronic device can operate multiple coil antennas using either of the above two operating methods. Therefore, the electronic device can use the operating methods to change the zero point, thereby increasing the success rate of payment.

[0340] Figure 46 This is a diagram illustrating a method of using multiple coil antennas according to an embodiment of the present disclosure.

[0341] refer to Figure 46 (a) through (d), according to this disclosure, the plurality of coil antennas for electronic devices can be implemented in various forms, for example, such as Figure 46 The flat coil antenna and solenoid antenna shown in (a), and Figure 46 The antenna form shown in (b) is similar to Figure 36B (in the form shown in the image). When a wearable device (e.g., a smartwatch) employs multiple coil antennas, these multiple coil antennas can be implemented by mounting the first coil antenna 4610 and the second coil antenna 4620 on the first and second watchbands, respectively, as shown in the image. Figure 46As shown in (c). Alternatively, multiple coil antennas can be mounted on the smartwatch, such that at least one of them is mounted on at least one watch band. Figure 46 As shown in (d), when an electronic device is configured to include two or more displays (e.g., LCDs), they may each include a separate coil antenna below the back of the LCD.

[0342] An electronic device with multiple coil antennas can operate all or some of them simultaneously at a specific time. The coil antennas can be selectively activated based on the electronic device's angle, movement, etc., relative to an external device (e.g., attachment information). The electronic device can display the well-identified area via an output device.

[0343] Figures 47A to 47C This is a diagram illustrating the format of data recorded in the track of a magnetic card according to an embodiment of the present disclosure.

[0344] refer to Figures 47A to 47C The magnetic stripe card stores data based on tracks 1, 2, and 3. The card reader, which may include a head and a coil, is configured to read data from the magnetic stripe tracks of the card. Swiping the magnetic stripe tracks (i.e., the magnetic black lines) across the head of the card reader's guide rails alters the magnetic field lines of the coil connected to the head. This change in magnetic field lines induces an electric current in the card reader. The card reader is then able to read and process the data recorded in the card tracks based on this induced current.

[0345] Electronic devices may include modules for storing data recorded in the track of a magnetic card and performing magnetic communication, such as an MST module. The MST module can transmit a magnetic field signal carrying the recorded track data to a card reader via an antenna. Upon receiving the magnetic field signal, the card reader induces the same current as when the magnetic card is swiped across its head. For example, payment can be made when a user places the electronic device near the card reader or touches the card reader with the electronic device.

[0346] Figure 48A and Figure 48B This is a diagram illustrating a data transmission method according to an embodiment of the present disclosure.

[0347] refer to Figure 48A and Figure 48B Data carried by the MST signal from the MST module can be sent via a token, such as... Figure 48A As shown. To use a token for payment, at least a portion of the data for track 1, 2, or 3, instead of track 1, track 2, or track 3, is replaced with a token or password. For example... Figure 48BAs shown, the PANs of tracks 1, 2, and 3 are replaced with tokens. The supplementary and free data of tracks 1 and 2, and the usage and security data and supplementary data of track 3 are replaced with ciphers. The replacement values ​​are converted into bits, which are then carried to the card reader by the MST signal. When using the track data format, the card reader can send the token information to the corresponding card issuer without processing the track data. The token may contain an identifier (ID) for card identification. Alternatively, the token may contain information for card issuer identification. Transaction data may include the card's expiration date, merchant ID, information created by combining parts of transaction-related information, etc.

[0348] The electronic device includes: a first cover forming the front side of the electronic device; a second cover forming the back side of the electronic device; a memory contained in a hollow region formed between the first and second covers; a display, at least a portion of which is contained in the hollow region and exposed through the first cover; a processor contained in the hollow region and electrically connected to the memory; and at least one loop antenna contained in the hollow region and electrically connected to the processor. The memory stores instructions enabling the processor to store data corresponding to tracks 1, 2, and 3 of the magnetic card in the memory, and to transmit magnetic field signals containing data corresponding to at least two of tracks 1, 2, and 3 within one cycle via the at least one loop antenna.

[0349] This instruction enables the processor to emit a magnetic field signal containing inverted data within one cycle. This inverted data is created when the binary numbers of the data corresponding to track 1 or track 2 are arranged in reverse order.

[0350] This instruction enables the processor to periodically transmit a first magnetic field signal multiple times, the first magnetic field signal containing data corresponding to one of orbits 1, 2, and 3, and then periodically transmit a second magnetic field signal multiple times containing inverted data, which is created when the binary numbers of the data used for the first magnetic field signal and the data corresponding to another orbit are arranged in reverse order.

[0351] This instruction enables the processor to transmit a second magnetic field signal at the same period as the first magnetic field signal.

[0352] After periodically transmitting the second magnetic field signal multiple times, the instruction enables the processor to periodically transmit the third magnetic field signal containing data multiple times, and periodically transmit the fourth magnetic field signal containing inverted data and the data multiple times.

[0353] This instruction enables the processor to transmit a third magnetic field signal at a longer cycle than the processor transmits the first magnetic field signal.

[0354] This instruction enables the processor to transmit a fourth magnetic field signal at a longer cycle than the processor transmits the second magnetic field signal.

[0355] This instruction enables the processor to transmit a fourth magnetic field signal at the same period as the third magnetic field signal.

[0356] This instruction enables the processor to emit a magnetic field signal containing data within a cycle, which is created when a portion of the data corresponding to the orbit is replaced by a token.

[0357] This instruction enables the processor to determine the emitted magnetic field signal based on at least a portion of the input received by the display and / or at least one sensor.

[0358] The sensors include fingerprint sensors.

[0359] This instruction enables the processor to transmit the same magnetic field signal via multiple loop antennas.

[0360] This instruction enables the processor to sequentially select multiple loop antennas and transmit the same magnetic field signal in the order of the selected loop antennas.

[0361] This instruction enables the processor to transmit magnetic field signals from other orbits via multiple loop antennas.

[0362] This instruction enables the processor to stop emitting magnetic field signals in response to user input and / or signals generated by at least one sensor.

[0363] The electronic device includes: a housing including a first side and a second side facing a direction opposite to the first side; a UI (e.g., display module 160) exposed through the first side; a memory located within the housing; a processor contained within the housing and electrically connected to the memory and the UI; and at least one conductive pattern (e.g., a loop antenna) contained within or formed as part of the housing and electrically connected to the processor. The memory temporarily stores first payment information in a first format and second payment information in a second format. For example, the memory may temporarily store information about at least two of tracks 1, 2, 3, and a token. The memory stores instructions that enable the processor to create multiple signal sequences using the first and / or second payment information and magnetically transmit the signal sequences to the outside via the conductive pattern. At least one of the signal sequences includes a pulse representing the entirety of the first and / or second payment information.

[0364] This instruction enables the processor to transmit a sequence of signals to the outside in response to a single input from the user received by the UI (e.g., the user's fingerprint 1370).

[0365] At least one signal sequence includes all the pulses that sequentially represent the first payment information and the second payment information.

[0366] The signal sequence includes a first signal comprising a pulse having a first pulse period, and a second signal comprising a pulse having a second pulse period different from the first pulse period.

[0367] The signal sequence includes a first signal, a second signal created after a first time interval starting from the first signal, and a third signal created after a second time interval starting from the second signal, wherein the second time interval is different from the first time interval.

[0368] At least one of the signal sequences includes a pulse representing information in the reverse order of the first payment information and the second payment information.

[0369] The memory temporarily stores the third payment information in a third format. The memory stores instructions that enable the processor to create a plurality of signal sequences using at least one of the first, second, and third payment information, and to magnetically transmit the signal sequences to the outside via a conductive pattern. At least one of the signal sequences includes pulses representing all of the first, second, and third payment information.

[0370] Figure 49 This is a flowchart illustrating a payment method according to an embodiment of the present disclosure.

[0371] refer to Figure 49 In step 4910, the electronic device displays a card selection screen. For example, the electronic device responds to user input by executing a payment application and displays an image corresponding to the card to be used for payment.

[0372] In step 4920, the electronic device performs user authentication. For example, the electronic device authenticates the user by acquiring the user's fingerprint via biosensor 107, determining whether the acquired fingerprint matches a stored fingerprint, and authenticating the user when the acquired fingerprint matches a stored fingerprint. It should be understood that user authentication by the electronic device can also be implemented by other methods, such as iris recognition via a camera, ECG pattern recognition via an electrocardiogram (ECG) sensor, and fingerprint recognition or a combination thereof.

[0373] Once user authentication is complete, in step 4930, the electronic device transmits an MST signal corresponding to the selected card image. The electronic device stops transmitting the MST signal when preset conditions for stop signal creation are met. Examples of situations where the electronic device meets the stop signal creation conditions include: the electronic device has received a payment completion message from the payment server; the electronic device recognizes that a preset time period has elapsed since the MST signal was first created; the electronic device recognizes that the UE (or the electronic device) is moving; the electronic device detects a sound indicating that payment has been completed via its microphone; and the electronic device receives user input to terminate the payment process.

[0374] Once user authentication is complete, the electronic device can create sequences in various combinations. For example, by combining simple transmission sequences with composite transmission sequences, the electronic device can create a total of 16 sequences within 20 seconds. Depending on the country or region, the electronic device is programmed with the most efficient sequence combinations, periods, pulse timings, etc., through field testing, and transmits the MST signal based on the programming results. The electronic device uses country codes, GPS information, etc., to identify the country or region, and performs payment processing using the MST based on the programming information corresponding to the identified country or region.

[0375] Once user authentication is complete, the electronic device can transmit a simple transmission sequence (e.g., multiple transmissions of an MST signal containing track 2 information). When user authentication is completed again after a period of time, the electronic device can retransmit the MST signal using a different method than before. For example, the electronic device can change the period, pulse timing, etc. The electronic device can also modify the information included in the MST signal to conform to a composite transmission sequence.

[0376] When payment via a simple transmission sequence fails, the user removes the electronic device from the reader and then reattaches it. In this case, the electronic device can identify the reader via sensors (e.g., accelerometer 103, gyroscope 105, proximity sensor, HRM sensor, etc.). Depending on the attachment operation, the electronic device can change the MST signal according to at least one of the subsequent transmission cycle, pulse timing, and sequence, and then transmit the changed MST signal.

[0377] Once user authentication is complete, whenever the user attaches the electronic device to the reader, the electronic device changes at least one of the following transmission period, pulse timing, and sequence, and then transmits the MST signal.

[0378] Electronic devices determine the remaining battery capacity or battery temperature. When an electronic device determines that the battery is rapidly depleting or that the battery is being heated through internal processing, it can initiate a simple transmission sequence.

[0379] Electronic devices change at least one of the transmission period, pulse timing, and sequence according to cellular communication and transmit MST signals. For example, when an electronic device is implemented to serve GSM, it can adjust the transmission period of the MST signal so that the MST signal is unaffected by the TDMA period.

[0380] The electronic device receives characteristics of the POS terminal, such as track and transmission period, from the beacon terminal installed in the store, and adjusts at least one of the transmission period, pulse timing, and sequence based on the received values.

[0381] A method of operating an electronic device includes: displaying an object associated with a card for payment, performing user authentication in response to a user's payment request, and, after completing user authentication, controlling a magnetic field communication module to transmit a magnetic field signal containing data corresponding to two or more of the card's tracks 1, 2, and 3 within a cycle.

[0382] The method also includes: controlling the magnetic field communication module to transmit a magnetic field signal containing inverted data in one cycle, the inverted data being created when the binary numbers of the data corresponding to orbit 1 or orbit 2 are arranged in reverse order.

[0383] The method also includes controlling the magnetic field communication module to periodically transmit a first magnetic field signal multiple times, the first magnetic field signal containing data corresponding to one of orbits 1, 2 and 3, and then periodically transmitting a second magnetic field signal containing inverted data, which is created when the binary numbers of the data for the first magnetic field signal and the data corresponding to another orbit are arranged in reverse order.

[0384] Figure 50 This is a block diagram illustrating the configuration of an electronic device according to an embodiment of the present disclosure.

[0385] refer to Figure 50 Electronic device 5001 can include Figure 1A and Figure 1B Some or all of the components in the electronic device 10.

For example, the communication module 5020 includes a cellular module 5021, a WiFi module 5023, a BT module 5025, a GNSS module 5026 (e.g., a GPS module, a GLONASS module, a BeiDou module, or a Galileo module), an NFC module 5027, an MST module 5028, and an RF module 5029.

[0388] For example, cellular module 5021 can provide voice calls, video calls, SMS services, internet services, etc., through a communication network.
