Description

Technical Field

[0001] The present disclosure relates to the field of terminal technology, and in particular to an antenna assembly and an electronic device. Background Art

[0002] In the related art, a mobile phone can be equipped with a satellite antenna and a non-satellite antenna. On the one hand, since the non-satellite antenna and the satellite antenna are very close and share the same ground, this will lead to serious coupling between the antennas and poor isolation, thus affecting the radiation efficiency of each antenna. On the other hand, Figure 1 It can be seen that the Tiantong satellite antenna A is located at the top of the mobile phone, and the non-satellite antennas B and C are located on two opposite side walls of the mobile phone.

[0049] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0050] In the related art, a mobile phone is provided with a non-satellite antenna, including but not limited to a cellular antenna (e.g., 2G, 3G, 4G, 5G antenna), a GPS antenna and a local area network antenna (including a limited local area network antenna and an unlimited local area network antenna (e.g., a WLAN antenna and a WiFi antenna)), and these non-satellite antennas can exist at the same time, or some of them can be selected to exist in the same mobile phone. In order to reduce the mutual influence between these non-satellite antennas, these non-satellite antennas can be linear antennas. Wire antennas include but are not limited to inverted-F antennas (IFA) and T-type antennas. The embodiment of the present disclosure is described by taking the satellite antenna as the Tiantong satellite antenna as an example, and it should be understood that the present disclosure is not limited to this.

[0051] In some embodiments, a satellite antenna may be added to the mobile phone, for example, the Tiantong-1 satellite mobile system (hereinafter referred to as "Tiantong satellite") antenna, corresponding to the transmission and reception of Tiantong satellite signals. The polarization mode of the Tiantong satellite is left-hand circular polarization, so the polarization mode of the Tiantong satellite antenna should also be left-hand circular polarization, so as to match the Tiantong satellite. In other embodiments, the satellite antenna in the mobile phone can also be matched with other communication satellites, and the polarization mode of other satellites can also be right-hand circular polarization, then the polarization mode of the satellite antenna is also right-hand circular polarization, that is, the polarization mode of the satellite antenna should be the same as the polarization mode of the corresponding satellite, so as to match.

[0052] Figure 1 The figure is a schematic diagram of a mobile phone according to an exemplary embodiment, and a satellite antenna A is arranged on the top of the mobile phone, and two non-satellite antennas are arranged on two opposite side walls of the mobile phone. On the one hand, since the non-satellite antenna and the satellite antenna are very close and share the same ground, this will lead to serious coupling between the antennas and poor isolation, thereby affecting the radiation efficiency of each antenna. On the other hand, Figure 1It can be seen that the Tiantong satellite antenna is located at the top of the mobile phone, and the non-satellite antennas B and C are located on two opposite side walls of the mobile phone. The Tiantong satellite antenna and the non-satellite antenna are set orthogonally. When the Tiantong satellite antenna is in working condition, since the non-satellite antenna is also in working condition at this time, there will still be electromagnetic waves on the non-satellite antenna. The electromagnetic waves on the non-satellite antenna will cause the non-satellite antenna to generate downward current, which will affect the left-hand circular polarization gain of the Tiantong satellite antenna, thereby weakening the performance of the Tiantong satellite antenna.

[0053] Figure 2A 1 is a block diagram of an antenna assembly 100 according to an exemplary embodiment, the antenna assembly 100 includes: a satellite antenna 300 and two non-satellite antennas 200; in the embodiment of the present disclosure, the number of non-satellite antennas can be one or more. The present disclosure is not limited to this. Here, the number of non-satellite antennas in the antenna assembly 100 is 2 for exemplary description, and it should be understood that the present disclosure is not limited to this.

[0054] At least one of the non-satellite antennas 200 includes: a first upper frame point 201 and a first selection circuit 204; wherein the first end of the first selection circuit 204 is connected to the first upper frame point 201, and the second end of the first selection circuit 204 is connected to the ground end; the first selection circuit 204 is used to select whether to connect the first upper frame point 201 to the ground end according to the state of the satellite antenna 300.

[0055] In the disclosed embodiment, a radio frequency signal can be input into a radiator in the non-satellite antenna 200 based on the first upper frame point 201, or a radio frequency signal can be received from the radiator. In some embodiments, a portion of the metal frame of the mobile phone can be used as the radiator of the non-satellite antenna 200, the first upper frame point 201 is located on the radiator of the non-satellite antenna 200, and at least one antenna gap can be set on the metal frame to prevent the metal frame from forming a loop. The antenna gap can also be used to form an antenna clearance, so that the non-satellite antenna 200 can complete the function of transmitting and receiving signals.

[0056] The arrangement and quantity of the antenna slots in the non-satellite antenna 200 may be set according to actual needs, and the present disclosure does not make any specific limitation thereto.

[0057] The disclosed embodiment is applied to an electronic device that integrates a satellite antenna 300 and at least one non-satellite antenna 200. By setting a first selection circuit 204 in the non-satellite antenna, it is possible to select whether to short the first upper frame point 204 to the ground terminal or to select to float the first upper frame point 204. Since the electromagnetic waves on the non-satellite antenna 200 may interfere with the satellite antenna 300, the first selection circuit 204 may select whether to connect the first upper frame point 204 to the ground terminal according to the state of the satellite antenna 300. The first selection circuit 204 is specifically used to: when the state of the satellite antenna 300 is in the working state, select to connect the first upper frame point 201 to the ground terminal; when the state of the satellite antenna 300 is in the non-working state, select not to connect the first upper frame point 201 to the ground terminal.

[0058] When the satellite antenna 300 is in the working state, since the first upper frame point 204 is short-circuited to the ground terminal, the electromagnetic wave of the non-satellite antenna 200 is weakened, thereby reducing the impact on the gain of the satellite antenna, thereby improving the gain of the satellite antenna. It can be understood that if all non-satellite antennas include the first selection circuit 204, when the satellite antenna is in the working state, by short-circuiting the first upper frame point 201 in each non-satellite antenna 200, the gain of the satellite antenna can be maximized.

[0059] When the satellite antenna 300 is in a non-operating state, generally speaking, the non-satellite antenna 200 is in an operating state, and the first upper frame point can be used to transmit and receive radio frequency signals without short-circuiting it.

[0060] The disclosed embodiment can also reduce the power consumption of the non-satellite antenna 200 by short-circuiting the first upper frame point 201 to the ground terminal when the satellite antenna 300 is in the working state, which is beneficial to improving the endurance of the electronic device.

[0061] Figure 2B It is a block diagram of an antenna assembly 100 according to an exemplary embodiment, wherein the non-satellite antenna 200 further includes: a first impedance circuit 203, wherein a first end of the first impedance circuit 203 is connected to the first upper frame point 201, and a second end of the first impedance circuit 203 is connected to a first end of the first selection circuit 201; or, a first end of the first impedance circuit 203 is connected to a second end of the first selection circuit 201, and a second end of the first impedance circuit 203 is connected to a ground terminal.

[0062] When the satellite antenna 300 is in a working state, the first selection circuit 204 is used to select and turn on the first impedance circuit 203 to connect the first upper frame point 201 to the ground end.

[0063] When the state of the satellite antenna 300 is a non-operating state, the first selection circuit 204 is used to select to disconnect the first impedance circuit 203 so as not to connect the first upper frame point 201 to the ground terminal.

[0064] In some embodiments, the first impedance circuit 203 includes a first resistor, and the resistance of the first resistor is less than or equal to 1 ohm. In the embodiment of the present disclosure, since the resistance of the first impedance circuit is small enough, it can also play a role of short-circuiting the first upper frame point 201.

[0065] In some embodiments, the first resistor comprises a zero ohm resistor.

[0066] Figure 2C 1 is a block diagram of an antenna assembly 100 according to an exemplary embodiment, wherein the non-satellite antenna 200 further includes: a first tuning circuit 202, wherein a first end of the first tuning circuit is connected to the first upper frame point, and a second end of the first tuning circuit is connected to a first end of the first selection circuit; or, a first end of the first tuning circuit is connected to a second end of the first selection circuit, and a second end of the first tuning circuit is connected to a ground terminal. The first tuning circuit 202 is used to tune the non-satellite antenna 300 to a desired resonant mode and a desired frequency band when the non-satellite antenna 300 is in an operating state.

[0067] The first selection circuit 204 is used to select whether to turn on the first tuning circuit 202 to tune the signal of the non-satellite antenna 200 .

[0068] When the non-satellite antenna is in a working state, the first tuning circuit 202 is turned on, so that the first upper frame point is connected to the ground terminal through the first tuning circuit 202;

[0069] When the satellite antenna is in a non-operating state, the first tuning circuit 202 is not turned on, and the first tuning circuit can be floated.

[0070] In some embodiments, the first tuning circuit 202 includes at least one tuning subcircuit, and the tuning subcircuit includes at least one of a capacitor, an inductor, and a resistor. The types of impedances included in each tuning subcircuit may be the same or different. For example, the types of impedances included in each tuning subcircuit are all inductors. In another example, the types of impedances included in each tuning subcircuit are all capacitors. In another example, the types of impedances included in each tuning subcircuit may be any combination of capacitors, inductors, and resistors. Inductors may be used to increase the frequency band covered by the antenna, and capacitors may be used to decrease the frequency band covered by the antenna. It is understandable that when the types of impedances included in each tuning subcircuit are all inductors, the frequency band covered by the antenna may be the lowest frequency band of low frequencies, and when the types of impedances included in each tuning subcircuit are all capacitors, the frequency band covered by the antenna may be the highest frequency band of high frequencies.

[0071] In some embodiments, the first selection circuit 204 is specifically configured to:

[0072] When the satellite antenna is in the working state, the second end of the first impedance circuit 203 in the non-satellite antenna 200 is selected to be connected to the ground end. Figure 3A , when the satellite antenna is in working state, the circuit connection status in two non-satellite antennas 200 (non-satellite antenna 2001 and non-satellite antenna 2002 respectively) is shown. Specifically, when the state of the satellite antenna is working state, the second end of the first impedance circuit 203 in the non-satellite antenna 2001 and the non-satellite antenna 2002 can be connected to the ground terminal. And the second end of the first tuning circuit 202 in the non-satellite antenna 2001 and the non-satellite antenna 2002 can be selected to float, or the second end of the first tuning circuit 202 in the non-satellite antenna 2001 and the non-satellite antenna 2002 can be selected to be connected to the ground terminal. Here, the first impedance circuit 203 plays the role of short-circuiting the first upper frame point 201. In this way, when the satellite antenna is in working state, since the electromagnetic waves on each non-satellite antenna 200 are suppressed, the downward current generated on the satellite antenna can be greatly reduced, so that the left-hand circular polarization gain of the Tiantong satellite antenna can be improved, thereby improving the performance of the satellite antenna.

[0073] When the satellite antenna is in a non-operating state, the second end of the first tuning circuit 202 in each non-satellite antenna 200 is connected to the ground, and the second end of the first impedance circuit 203 is floated. Figure 3B2 shows the circuit connection status of two non-satellite antennas 200 (non-satellite antenna 2001 and non-satellite antenna 2002) when the satellite antenna is in a non-operating state. Specifically, when the state of the satellite antenna is in a non-operating state, the second end of the first tuning circuit 202 in the non-satellite antenna 2001 and the non-satellite antenna 2002 can be connected to the ground terminal. Here, the first impedance circuit 203 does not short-circuit the first upper frame point 201. The first upper frame point 201 can still normally transmit and receive radio frequency signals.

[0074] It should be noted that the choice of connecting the second end of the first tuning circuit 202 to the ground terminal here can be to connect at least one tuning sub-circuit in the first tuning circuit 202 to the ground terminal, without having to connect every tuning sub-circuit in the first tuning circuit 202 to the ground terminal.

[0075] In some embodiments, the first selection circuit 204 includes a multi-pole multi-throw switch. On the one hand, the multi-pole multi-throw switch can be used to individually turn on or off each tuning sub-circuit in the first tuning circuit 202, so that the non-satellite antenna 200 can be tuned to a desired resonant mode and a desired frequency band. On the other hand, the multi-pole multi-throw switch can be used to individually turn on or off the first impedance circuit 203 to cooperate with the use of the satellite antenna.

[0076] The disclosed embodiment is applied to an electronic device that integrates a satellite antenna 300 and at least one non-satellite antenna 200. By setting a first impedance circuit 203 and a first tuning circuit 202 between a first upper frame point 201 of at least one non-satellite antenna 200 and a ground terminal, when the satellite antenna is in operation, by turning on the first impedance circuit 203 in the non-satellite antenna 200, the first upper frame point 201 can be returned to the ground, thereby short-circuiting the first upper frame point 201, and preventing the electromagnetic waves of the non-satellite antenna 200 from affecting the gain of the satellite antenna, thereby improving the gain of the satellite antenna. It can be understood that if all non-satellite antennas include the first impedance circuit 203 and the first tuning circuit 202, when the satellite antenna is in operation, by turning on the first impedance circuit 203 in each non-satellite antenna 200, the gain of the satellite antenna can be maximized. The disclosed embodiment can also disconnect the first impedance circuit 203 in each non-satellite antenna 200 and turn on the first tuning circuit 202 when the satellite antenna 300 is in a non-working state, so that the first upper frame point 201 can normally receive the radio frequency signal, thereby allowing the non-satellite antenna 200 to work normally.

[0077] Figure 4 is a circuit diagram of another antenna assembly 100 according to an exemplary embodiment, wherein the non-satellite antenna 200 further includes: a first feed source 206, a first matching circuit 205;

[0078] The first end of the first matching circuit 205 is connected to the first feeding point, the first end of the first matching circuit 205 is also connected to the first end of the first tuning circuit 202 and the first end of the first impedance circuit 203, and the second end of the first matching circuit 205 is connected to the first end of the first feed source 206.

[0079] The first feed source 206 is used to provide a radio frequency signal to the first feed point or receive a radio frequency signal from the first feed point. Specifically, the radio frequency signal received by the first feed point is frequency modulated by the first tuning circuit 202, and the frequency modulated radio frequency signal is sent to the first feed source 206. The radio frequency signal emitted by the first feed source 206 is frequency modulated by the first tuning circuit 202, and the frequency modulated radio frequency signal is sent to the first feed point. According to the difference in the frequency modulated radio frequency signal, the current on the antenna radiator changes accordingly, resulting in a change in the electrical length of the antenna radiation, thereby changing the frequency band covered by the antenna.

[0080] In some embodiments, the first upper frame point includes a first feed point, and the first feed point is connected to the first feed source 206.

[0081] In some embodiments, the first matching circuit 205 includes capacitors or inductors. The number and specific parameter values ​​of the capacitors or inductors in the first matching circuit 205 can be determined by performing impedance matching at the resonant frequencies of various frequency bands.

[0082] In some embodiments, when the satellite antenna is in working state, the second end of the first impedance circuit 203 can be connected to the ground, and the first tuning circuit 202 can be floated. Since the first matching circuit 205 is turned on, it is ensured that the first feed source 206 is not short-circuited.

[0083] In some embodiments, when the satellite antenna is in the working state, the second end of the first impedance circuit 203 and the second end of the first tuning circuit 202 may be connected to the ground terminal, thereby ensuring that the first feed source 206 is not short-circuited.

[0084] Figure 5 is a circuit diagram of another antenna assembly 100 according to an exemplary embodiment, wherein the non-satellite antenna 200 further includes: a filter circuit 207, a second impedance circuit 208, a second selection circuit 209 and a radio frequency transceiver 210;

[0085] The first end of the filter circuit 207 and the first end of the second impedance circuit 208 are both connected to the second end of the first feed source 206, the second end of the filter circuit 207 and the second end of the second impedance circuit 208 are both connected to the first end of the second selection circuit 209, and the second end of the second selection circuit 209 is connected to the RF transceiver 210;

[0086] The second selection circuit 209 is used for selecting one of the second end of the second impedance circuit 208 and the second end of the filter circuit 207 to connect to the RF transceiver 210 according to the state of the satellite antenna.

[0087] The filter circuit 207 in the embodiment of the present disclosure is used to allow radio frequency signals within a preset frequency band to pass through. For example, it can be used to allow radio frequency signals within the 4G and 5G frequency bands to pass through.

[0088] Reference Figure 5 As shown, the filter circuit 207 may include multiple filters, for example, it may include a first filter 2071 and a second filter 2072. For example, the first filter 2071 may be a low-pass filter, that is, it allows RF signals with frequencies lower than a certain frequency to pass through, and attenuates RF signals higher than this frequency. The second filter 2072 may be a high-pass filter, that is, it allows RF signals with frequencies higher than a certain frequency to pass through, and attenuates RF signals lower than this frequency. For another example, the first filter 2071 may be a first band-pass filter, which is used to allow RF signals of a first preset frequency band to pass through, and the second filter 2072 may be a second band-pass filter, which is used to allow RF signals of a second preset frequency band to pass through, and the first preset frequency band is not completely the same as the second preset frequency band. It can be understood that the number and type of filters in the filter circuit 207 in the embodiment of the present disclosure are examples, and can be set accordingly according to actual conditions, and the present disclosure is not limited to this.

[0089] The second impedance circuit 208 is used to prevent the radio frequency signal emitted by the radio frequency transceiver 210 from transmitting to the first feed source 206 or attenuate the radio frequency signal emitted by the radio frequency transceiver 210 to weaken the influence of the first feed source 206 on the first upper frame point 201, thereby weakening the radio frequency signal at the first upper frame point 201, so as to further improve the influence of the non-satellite antenna on the circular polarization gain on the satellite antenna. In some embodiments, the second impedance circuit 208 includes a second resistor, and the resistance value of the second resistor is greater than or equal to 100 ohms.

[0090] The RF transceiver 210 in the embodiment of the present disclosure is used to receive RF signals and convert them into digital signals, or convert digital signals into RF signals and send them out. In some embodiments, the RF transceiver 210 may also include a power amplifier (PA). The power amplifier may amplify the received RF signal and transmit it to the RF transceiver 210.

[0091] In the embodiment of the present disclosure, the second selection circuit 209 is used to select one of the second end of the second impedance circuit and the second end of the filter circuit 207 to connect to the RF transceiver 210 according to the state of the satellite antenna.

[0092] In some embodiments, the second selection circuit 209 is specifically used for:

[0093] When the satellite antenna is in working state, the second end of the second impedance circuit is selected to be connected to the RF transceiver 210; in this way, the RF signal emitted by the RF transceiver 210 of the non-satellite antenna 200 can be prevented from being transmitted to the first feed source 206 or the RF signal emitted by the RF transceiver 210 can be attenuated to weaken the influence of the first feed source 206 on the first upper frame point 201, thereby weakening the RF signal at the first upper frame point 201, so as to further improve the influence of the non-satellite antenna on the circular polarization gain on the satellite antenna.

[0094] When the state of the satellite antenna is non-operating, the second end of the filter circuit 207 is selected to be connected to the RF transceiver 210. At this time, the RF signal sent by the RF transceiver 210 of the non-satellite antenna 200 can be normally transmitted to the first upper frame point 201. The non-satellite antenna 200 can thus work normally.

[0095] In some embodiments, the second selection circuit 209 includes a multi-pole multi-throw switch.

[0096] In some embodiments, the non-satellite antenna 200 includes at least one of the following:

[0097] Cellular antenna, LAN antenna, GPS antenna.

[0098] In some embodiments, the satellite antenna includes a second feed point, a second tuning circuit, a third impedance circuit, and a third selection circuit; wherein,

[0099] The first end of the second tuning circuit and the first end of the third impedance circuit are both connected to the second feeding point, the second end of the second tuning circuit and the second end of the third impedance circuit are both connected to the first end of the third selection circuit, and the second end of the third selection circuit is connected to the ground terminal; the third selection circuit is used to select one of the second end of the second tuning circuit and the second end of the third impedance circuit to be connected to the ground terminal according to the state of the satellite antenna.

[0100] In the disclosed embodiment, the structure of the satellite antenna may be the same as or similar to the structure of the non-satellite antenna 200. The difference is that the parameter value in the second tuning circuit in the satellite antenna is different from the parameter value in the first tuning circuit 202 in the non-satellite antenna 200. The RF transceiver in the satellite antenna is different from the RF transceiver 210 in the non-satellite antenna 200.

[0101] When the non-satellite antenna 200 is in the working state, the third selection circuit is used to select to connect the third impedance circuit in the satellite antenna to the ground terminal, so as to prevent the electromagnetic waves on the satellite antenna from interfering with the non-satellite antenna 200.

[0102] When the non-satellite antenna 200 is in a non-operating state, the third selection circuit is used to select to connect the second tuning circuit in the satellite antenna to the ground terminal, so that the second feeding point in the satellite antenna can normally receive and transmit radio frequency signals.

[0103] In some embodiments, the polarization direction of the satellite antenna is 90° to the polarization direction of the non-satellite antenna. For example, the polarization direction of the satellite antenna is 90° to the polarization direction of each non-satellite antenna.

[0104] Figure 6 A schematic diagram of an electronic device 1000 according to an exemplary embodiment is shown, which includes the antenna assembly 100 as described in any of the above embodiments.

[0105] The electronic device in the embodiments of the present disclosure may include a terminal device, for example, a mobile terminal or a fixed terminal. The mobile terminal may include: a mobile phone, a tablet computer, a laptop computer, a wearable electronic device, etc. The fixed terminal may include: a desktop computer, a smart TV, a vehicle-mounted device, etc.

[0106] In some embodiments, the non-satellite antenna is located on the side of the electronic device, and the satellite antenna is located on the top of the electronic device. Here, the non-satellite antenna can be located on one side of the electronic device or on both sides of the electronic device, and multiple non-satellite antennas can be arranged on one side. In some embodiments, the polarization direction of the satellite antenna is 90° to the polarization direction of the non-satellite antenna.

[0107] The satellite antenna is located on the top of the electronic device. The top of the electronic device here refers to the top of the electronic device when it is picked up by the user for use, that is, when it is facing the user. Placing the satellite antenna on the top of the electronic device is conducive to the electronic device to better send and receive satellite signals.

[0108] Figure 7 According to a schematic diagram of the use angle range of an electronic device shown in an exemplary embodiment, taking the electronic device as a mobile phone as an example, its preferred use angle range is (between -15° and 15°), where 0° is defined as the angle when the mobile phone is placed vertically on the ground.

[0109] Figure 8 Different gains of satellite antennas under different schemes are shown. Scheme 1: When the state of the satellite antenna is in working state, the first impedance circuit in the non-satellite antenna is selected to be connected to the ground terminal. And scheme 2: When the state of the satellite antenna is in working state, the first tuning circuit in the non-satellite antenna is connected to the ground terminal. At the transmission frequency of the Tiantong satellite (for example, f=1.98GHZ) and when the mobile phone is at 0°, scheme 1 is adopted, that is, when the non-satellite antenna is short-circuited, the gain of the Tiantong satellite is -4. When scheme 2 is adopted, that is, when the non-satellite antenna is not short-circuited, the gain of the Tiantong satellite is -5.2. It can be seen from the experimental data that the left-hand circular polarization gain of the satellite antenna is improved by using the embodiment of the present disclosure.
