Description

Technical Field

[0001] The present disclosure relates to a communication system, and more particularly to an antenna module including a plurality of floating radiators and an electronic device including the antenna module. Background Art

[0002] In order to meet the demand for wireless data traffic that has increased since the deployment of the fourth generation (4G) communication system, efforts have been made to develop improved fifth generation (5G) or pre-5G communication systems. Therefore, 5G or pre-5G communication systems are also called "super 4G networks" or "post-long term evolution (LTE) systems". 5G communication systems are considered to be implemented in higher frequency (millimeter wave) bands (such as the 60 GHz band), thereby achieving higher data rates. In order to reduce the propagation loss of radio waves and increase the transmission distance, beamforming, massive multiple input multiple output (MIMO), full-dimensional MIMO (FD-MIMO), array antennas, analog beamforming, and massive antenna technology are discussed in 5G communication systems. In addition, in 5G communication systems, system network improvements are being developed based on advanced small cells, cloud radio access networks (RANs), ultra-dense networks, device-to-device (D2D) communications, wireless backhaul, mobile networks, collaborative communications, coordinated multipoint (CoMP), receiving-end interference cancellation, etc. In 5G systems, hybrid frequency shift keying (FSK) and quadrature amplitude modulation (QAM) modulation (FQAM) and sliding window superposition coding (SWSC) have been developed as advanced coding modulation (ACM), and filter bank multi-carrier (FBMC), non-orthogonal multiple access (NOMA) and sparse code multiple access (SCMA) as advanced access technologies.

[0003] The Internet (a human-centric connected network where humans generate and consume information) is now evolving into the Internet of Things (IoT), in which distributed entities (such as things) exchange and process information without human intervention. The Internet of Everything (IoE) has emerged, combining IoT technologies with big data processing technologies through connectivity to cloud servers. As technological elements such as "sensing technology," "wired / wireless communication and network infrastructure," "service interface technology," and "security technology" have become essential for IoT implementation, research has recently begun on sensor networks, machine-to-machine (M2M) communication, and machine-type communication (MTC). Such an IoT environment can provide intelligent Internet technology services that create new value for human life by collecting and analyzing data generated between connected things. Through the convergence and integration of existing information technology (IT) and various industrial applications, the IoT can be applied in a variety of fields, including smart homes, smart buildings, smart cities, smart cars or connected vehicles, smart grids, healthcare, smart appliances, and advanced medical services.

[0004] In line with this, various attempts have been made to apply 5G communication systems to IoT networks. For example, technologies such as sensor networks, machine-type communications (MTC), and machine-to-machine (M2M) communications can be implemented through beamforming, MIMO, and array antennas. Cloud radio access networks (RANs), as an application of the aforementioned big data processing technologies, can also be considered an example of the convergence between 5G and IoT technologies.

[0005] The above information is presented as background information only to assist with an understanding of the present disclosure. No determination has been made, and no assertion is made, as to whether any of the above might be applicable as prior art with respect to the present disclosure. Summary of the Invention

[0061] Figure 1 is a block diagram illustrating an electronic device in a network environment according to an embodiment of the present disclosure.

[0062] Reference Figure 1 The electronic device 10 in the network environment can communicate with any other electronic device (not shown) or a server (not shown) through a network (eg, a wired or wireless communication network). For example, the electronic device 10 may be a base station and the other electronic device may be a terminal.

[0063] According to one embodiment, the electronic device 10 may include an antenna module 11, a communication module 12, a processor 13, a memory 14, and an interface 15. In some embodiments, at least one of the components may be omitted from the electronic device 10, or one or more other components may be added to the electronic device 10. In some embodiments, some of the components may be integrated into a single element.

[0064] The processor 13 may control, for example, at least one other component (e.g., hardware or software component) of the electronic device 10 that is coupled to the processor 13, and may perform various data processing or calculations. According to one embodiment, as at least part of the data processing or calculation, the processor 13 may store commands or data received from another component (e.g., the communication module 12) in the memory 14, process the commands or data stored in the memory 14, and store the resulting data in the memory 14.

[0065] The memory 14 may store various data used by at least one component of the electronic device 10. The data may include, for example, software and input data or output data for commands related thereto.

[0066] The interface 15 may support one or more designated protocols that may be used for the electronic device 10 to directly or wirelessly connect with any other electronic device. According to another embodiment, the interface 15 may include, for example, a Universal Serial Bus (USB) interface or a Secure Digital (SD) card interface.

[0067] The communication module 12 can support the establishment of a wired communication channel or a wireless communication channel between the electronic device 10 and any other electronic device, and communicate through the established communication channel. The communication module 12 may include one or more communication processors that can operate independently of the processor 13 and support wired communication or wireless communication. According to another embodiment, the communication module 12 can communicate with any other electronic device or server via a traditional cellular network, a 5G network, a next-generation communication network, the Internet or a computer network (such as a LAN or WAN). These various types of communication modules can be implemented as a single component (such as a single chip), or can be implemented as multiple components (such as multiple chips) separated from each other.

[0068] The communication module 12 can support 5G networks and next-generation communication technologies beyond 4G networks, such as new radio (NR) access technology. NR access technology can support high-speed transmission of high-capacity data (enhanced mobile broadband (eMBB)), terminal power minimization and multi-terminal access (massive machine type communication (mMTC)) or ultra-reliable and low-latency communication (URLLC). For example, the communication module 12 can support ultra-high frequency (millimeter wave) bands to achieve higher data rates. The communication module 12 can support various technologies for ensuring performance in ultra-high frequency bands, such as beamforming, massive multiple-input multiple-output (massive MIMO), full-dimensional MIMO (FD-MIMO), array antennas, analog beamforming, and massive antenna technology. The communication module 12 supports various requirements specified for the electronic device 10, any other electronic device, or network system.

[0069] The antenna module 11 can send signals or power to the outside of the electronic device 10 (e.g., any other electronic device), or receive signals or power from the outside of the electronic device 10 (e.g., any other electronic device). According to another embodiment, the antenna module 11 may include an antenna including a radiating element composed of a conductive material or a conductive pattern formed on a substrate (e.g., a PCB). According to another embodiment, the antenna module 11 may include a plurality of antennas. In such a case, at least one antenna suitable for a communication scheme used in the network may be selected, for example, by the communication module 12 from the plurality of antennas. Signals or power can then be sent or received between the communication module 12 and any other external electronic device via the selected at least one antenna. According to some embodiments, additional components other than the radiating element (e.g., a radio frequency integrated circuit (RFIC)) may be additionally formed as part of the antenna module 11.

[0070] According to various embodiments, the antenna module 11 may form a millimeter wave antenna module. According to another embodiment, the millimeter wave antenna module may include a printed circuit board, an RFIC disposed on or adjacent to a first surface (e.g., a lower surface) of the printed circuit board and capable of supporting a specified high-frequency band (e.g., a millimeter wave band), and a plurality of antennas (e.g., array antennas) disposed on or adjacent to a second surface (e.g., an upper surface or a side surface) of the printed circuit board and capable of transmitting or receiving signals in the specified high-frequency band.

[0071] At least some of the above components can be interconnected via an inter-peripheral communication scheme (such as a bus, general-purpose input and output (GPIO), serial peripheral interface (SPI) or mobile industry processor interface (MIPI)) and pass signals (such as commands or data) between them.

[0072] According to another embodiment, commands or data can be sent or received between the electronic device 10 and any other external electronic device via a server connected to the network. The other external electronic device can be a device of the same type or a different type as the electronic device 10. According to another embodiment, all or some of the operations to be performed at the electronic device 10 can be performed at the other external electronic device. For example, if the electronic device 10 should perform a function or service automatically or in response to a request from a user or another device, instead of performing the function or service, or in addition to performing the function or service, the electronic device 10 can request one or more other external electronic devices to perform at least part of the function or service. The one or more other external electronic devices that receive the request can perform at least part of the requested function or service, or additional functions or additional services related to the request, and transmit the results of the execution to the electronic device 10. The electronic device 10 can provide the result as at least part of the response to the request with or without further processing the result. To this end, for example, cloud computing, distributed computing, mobile edge computing (MEC) or client-server computing technology can be used. The electronic device 10 can use distributed computing or MEC to provide, for example, ultra-low latency services. In other embodiments, the other external electronic devices may include Internet of Things (IoT) devices.

With respect to the description of the accompanying drawings, similar figure numerals may be used to represent similar or related elements. The singular form of the noun corresponding to an item may include one or more of the items, unless the relevant context clearly indicates otherwise. As used herein, each of the phrases such as "A or B", "at least one of A and B", "at least one of A or B", "A, B or C", "at least one of A, B and C" and "at least one of A, B or C" may include all possible combinations of the items listed together in the corresponding one of the phrases. As used herein, terms such as "first", "second", "the first" and "the second" may be used to simply distinguish the corresponding element from another, and do not limit these elements in other aspects (such as importance or order). It will be understood that if an element (e.g., a first element) is referred to as being “coupled” / “coupled to” another element (e.g., a second element) or “connected” / “connected to” another element (e.g., a second element), with or without the term “operably” or “communicatively”, this means that the element can be coupled / connected to the other element or to the third element directly (e.g., wired), wirelessly, or via a third element.

[0075] As used herein, the term "module" may include units implemented in hardware, software, or firmware, and may be used interchangeably with other terms (such as "logic," "logic block," "component," or "circuit"). A "module" may be the smallest unit of a single integrated component suitable for performing one or more functions, or a portion thereof. For example, according to another embodiment, a "module" may be implemented in the form of an application-specific integrated circuit (ASIC).

[0076] The various embodiments as described herein can be implemented as software comprising one or more instructions stored in a storage medium (e.g., memory 14) that can be read by a machine (e.g., electronic device 10). For example, a processor (e.g., processor 13) of a machine (e.g., electronic device 10) can call at least one of the one or more stored instructions from the storage medium and execute it. This allows the machine to be operated to perform at least one function according to the at least one instruction called. The one or more instructions may include code generated by a compiler or code executable by an interpreter. The machine-readable storage medium may be provided in the form of a non-transitory storage medium. The term "non-transitory" merely means that the storage medium is a tangible device and does not include signals (e.g., electromagnetic waves), but this term does not distinguish between data being semi-permanently stored in a storage medium and data being temporarily stored in a storage medium.

[0077] According to another embodiment, the methods according to various embodiments of the present disclosure may be included in and provided in a computer program product. The computer program product may be traded as a product between a seller and a buyer. The computer program product may be distributed in the form of a machine-readable storage medium (e.g., a compact disc read-only memory (CD-ROM)) or via an app store (e.g., the Play Store). TM ) online distribution (e.g., download or upload), or directly between two user devices (e.g., smartphones). If distributed online, at least part of the computer program product may be temporarily generated or at least temporarily stored in a machine-readable storage medium, such as a memory of a manufacturer's server, an application store's server, or a relay server.

[0078] According to various embodiments, each element (such as module or program) in the above-mentioned elements can include single entity or multiple entities, and some of these multiple entities can be arranged in any other element individually. According to various embodiments, one or more of the above-mentioned elements can be omitted, or one or more other elements can be added. Alternatively or additionally, multiple elements (such as module or program) can be integrated into a single element. In this case, according to various embodiments, the integrated element can still perform one or more functions of each of the multiple elements in the same or similar manner as they were performed by the corresponding element in the multiple elements before integration. According to various embodiments, the operation performed by module, program or another element can be performed sequentially, in parallel, repeatedly or heuristically, or one or more of the operations can be performed in different orders or omitted, or one or more other operations can be added.

[0079] Figure 2is a graph showing the antenna gain of the antenna module of the electronic device according to one embodiment of the present disclosure.

[0080] Reference Figure 2 In the curve 20 of the antenna gain of the electromagnetic wave radiated from the antenna module 11 of the electronic device 10, the value 21 in the forward direction and the values 22 and 23 in the lateral directions may be different from each other. The lateral ratio of the antenna may be defined as the difference between the antenna gain value 21 with respect to the forward direction and the antenna gain value 21 or 22 with respect to the lateral direction of the electromagnetic wave radiated from the antenna module 11.

[0081] For example, antenna module 11 may include multiple antenna arrays. In this case, when the amount of electromagnetic waves radiated from one antenna array in the lateral direction is small, the influence on the other antenna arrays located on the side surface of the one antenna array can be reduced. For example, when the side-to-side ratio of each of the multiple antenna arrays of antenna module 11 is reduced, the mutual influence of the multiple antenna arrays can be reduced.

The second floating radiators 220a to 220j may be spaced a predetermined distance from the second antenna elements 120a to 120c.

[0100] The third floating radiators 230a to 230j may be disposed between the second antenna elements 120a to 120c and the third antenna elements 130a to 130c on the upper surface of the board 100. For example, the third floating radiators 230a to 230j may be disposed to the right of the second antenna elements 120a to 120c. The third floating radiators 230a to 230j may be spaced a predetermined distance from the second antenna elements 120a to 120c. The third floating radiators 230a to 230j may be disposed to the left of the third antenna elements 130a to 130c. The third floating radiators 230a to 230j may be spaced a predetermined distance from the third antenna elements 130a to 130c.

[0101] The fourth floating radiators 240a to 240j may be disposed on the upper surface of the board 100 between the third antenna elements 130a to 130c and the fourth antenna elements 140a to 140c. For example, the fourth floating radiators 240a to 240j may be disposed to the right of the third antenna elements 130a to 130c. The fourth floating radiators 240a to 240j may be spaced a predetermined distance from the third antenna elements 130a to 130c. The fourth floating radiators 240a to 240j may be disposed to the left of the fourth antenna elements 140a to 140c. The fourth floating radiators 240a to 240j may be spaced a predetermined distance from the fourth antenna elements 140a to 140c.

[0102] The fifth floating radiators 250a to 250j may be disposed on the left side of the fourth antenna elements 140a to 140c on the upper surface of the board 100. The fifth floating radiators 250a to 250j may be spaced apart from the fourth antenna elements 140a to 140c by a predetermined distance.

[0103] The directivity of the beam radiated from the antenna module 11 may be proportional to the width of the aperture of the antenna module 11 radiating the beam. For example, as the aperture of the antenna module 11 increases, the width of the beam radiated from the antenna module 11 may decrease.

[0104] The antenna module 11 can increase the aperture of the antenna module 11 through the plurality of floating radiators 210a to 250c. That is, the antenna module 11 can reduce the width of the beam radiated from the antenna module 11 through the plurality of floating radiators 210a to 250c. Therefore, the antenna module 11 can increase the directivity of the beam radiated from the antenna module 11 through the plurality of floating radiators 210a to 250c.

[0105] In addition, the antenna module 11 may reduce surface waves caused by electromagnetic waves radiated from the multiple antenna elements 110 a to 140 c through the plurality of floating radiators 210 a to 250 c .

The 1a-th floating radiator 210a may be disposed on the board 100 and spaced apart from the left side of the 1a-th antenna element 110a by a predetermined distance d. The upper surface of the 1a-th floating radiator 210a may be spaced apart from the upper surface of the board 100 by a predetermined distance h2. The horizontal width w of the 1a-th floating radiator 210a may have a predetermined size.

[0107] Figure 5 FIG. 1 is a top view of an antenna module of an electronic device according to an embodiment of the present disclosure.

[0108] Reference Figure 5 , the plurality of floating radiators 210 a to 210 e and 220 a to 220 e of the antenna module 11 may be electromagnetically coupled to the plurality of antenna elements 110 a to 110 b .

[0109] For example, the plurality of antenna elements 110a to 110b may radiate a first electromagnetic wave. The first electromagnetic wave radiated from the plurality of antenna elements 110a to 110b may induce an electromagnetic field in the plurality of floating radiators 210a to 210e and 220a to 220e. For example, due to the electromagnetic field induced by the first electromagnetic wave, the plurality of floating radiators 210a to 210e and 220a to 220e may radiate a second electromagnetic wave.

[0110] Due to the plurality of floating radiators 210a to 210e and 220a to 220e, the antenna module 11 can have a wider aperture. The antenna module 11 can radiate a beam based on the first electromagnetic wave and the second electromagnetic wave. For example, the width of the beam radiated from the antenna module 11 can be narrowed by the first electromagnetic wave and the second electromagnetic wave.

[0111] The plurality of floating radiators 210a to 210e and 220a to 220e may prevent the first electromagnetic wave radiated from the plurality of antenna elements 110a to 110b from propagating to the surface of the antenna module 11. For example, the plurality of floating radiators 210a to 210e and 220a to 220e may reduce the influence of surface waves caused by the first electromagnetic wave.

[0112] The plurality of floating radiators 210a to 210e and 220a to 220e may have capacitance factors and inductance factors. For example, the second-a floating radiator 220a may have multiple inductance factors and capacitance factors. For example, the inductance factor may be referred to as an inductor. The capacitance factor may be referred to as a capacitor. For example, the second-a floating radiator 220a may include a plurality of inductors 511 to 514 and a capacitor 520. The first end of the first inductor 511 may be electrically connected to the first end of the fourth inductor 514. The second end of the first inductor 511 may be electrically connected to the first end of the second inductor 512. The second end of the second inductor 512 may be electrically connected to the first end of the third inductor 513. The second end of the third inductor 513 may be electrically connected to the first end of the fourth inductor 514. One end of the capacitor 520 may be electrically connected to the third end of the first inductor 511. One end of the capacitor 520 may be electrically connected to the third end of the third inductor 513 .

[0113] The capacitance factor and inductance factor of each of the plurality of floating radiators 210a to 210e and 220a to 220e may be determined based on at least one of the horizontal length, vertical length, thickness, and line width of each of the plurality of floating radiators 210a to 210e and 220a to 220e. For example, the factor value of each of the plurality of inductors 511 to 514 and the capacitor 520 may be determined based on at least one of the horizontal length, vertical length, thickness, and line width of the 2a-th floating radiator 220a. For example, the imaginary part of the factor value of each of the plurality of inductors 511 to 514 and the capacitor 520 may be determined based on at least one of the horizontal length, vertical length, thickness, and line width of the 2a-th floating radiator 220a. For example, the imaginary part of the inductance value of each of the plurality of inductors 511 to 514 and the imaginary part of the capacitance value of the capacitor 520 may be determined based on at least one of the horizontal length, vertical length, thickness, and line width of the 2a-th floating radiator 220a.

[0114] The phase of the second electromagnetic wave radiated from the 2a-th floating radiator 220a may be determined based on the imaginary part of the factor value of each of the plurality of inductors 511 to 514 and the capacitor 520. That is, the phase of the second electromagnetic wave radiated from the 2a-th floating radiator 220a may be determined based on at least one of the horizontal length, vertical length, thickness, and line width of the 2a-th floating radiator 220a. At least one of the horizontal length, vertical length, thickness, and line width of the 2a-th floating radiator 220a may be determined so that the phase of the second electromagnetic wave is the same as the phase of the first electromagnetic wave.

[0116] Reference Figure 6 , an upper surface of the body 111 a of the 1a-th antenna element 110 a of the antenna module 11 may be spaced apart from an upper surface of the board 100 by a predetermined distance h1 .

[0117] The 1a-th floating radiator 210a may include a 1a-th body 211a and a 1a-th support 212a. For example, the 1a-th support 212a may be disposed on the upper surface of the board 100. Alternatively, the 1a-th support 212a may be integrally injection-molded with the board 100.

[0118] The first body 211a may be disposed on the upper surface of the first support 212a. The first body 211a may be disposed on the board 100 at a predetermined distance d from the left side of the first antenna element 110a. The upper surface of the first body 211a may be spaced a predetermined distance h2 from the upper surface of the board 100.

[0119] Figure 5 The factor value of each of the plurality of inductors 511 to 514 and the capacitor 520 can be determined based on the thickness t and the horizontal or vertical width length w of the first body 211a. For example, the imaginary part of the factor value of each of the plurality of inductors 511 to 514 and the capacitor 520 can be determined based on at least one of the thickness t and the horizontal or vertical width length w of the first body 211a. For example, the imaginary part of the inductance value of each of the plurality of inductors 511 to 514 and the imaginary part of the capacitance value of the capacitor 520 can be determined based on at least one of the thickness t and the horizontal or vertical width length w of the first body 211a.

[0120] The direction of the second electromagnetic wave radiated from the 1a-th floating radiator 210a may be based on Figure 5The imaginary part of the factor value of each of the plurality of inductors 511 to 514 and the capacitor 520 is determined. That is, the phase of the second electromagnetic wave radiated from the 1a-th floating radiator 210a can be determined based on at least one of the thickness t and the horizontal or vertical length w of the 1a-th body 211a. At least one of the thickness t and the horizontal or vertical length w of the 1a-th body 211a can be determined so that the phase of the second electromagnetic wave is the same as the radiation direction of the first electromagnetic wave.

[0121] The 2a-th floating radiator 220a may include a 2a-th body 221a and a 2a-th support 222a. For example, the 2a-th support 222a may be disposed on the upper surface of the board 100. Alternatively, the 2a-th support 222a may be integrally injection-molded with the board 100.

[0122] The 2a-th body 221a may be disposed on the upper surface of the 2a-th support 222a. The 2a-th body 221a may be disposed on the board 100 and spaced a predetermined distance d from the right side of the 1a-th antenna element 110a. The upper surface of the 2a-th body 221a may be spaced a predetermined distance from the upper surface of the board 100.

[0123] The distance h1 from the upper surface of the board 100 to the upper surface of the body 111a of the 1a-th antenna element 110a, the distance h2 from the upper surface of the board 100 to the upper surface of the 1a-th body 211a of the 1a-th floating radiator 210a, and the distance from the upper surface of the board 100 to the upper surface of the 2a-th body 221a of the 2a-th floating radiator 220a may be the same or similar. Alternatively, the distance h1 from the upper surface of the board 100 to the upper surface of the body 111a of the 1a-th antenna element 110a, the distance h2 from the upper surface of the board 100 to the upper surface of the 1a-th body 211a of the 1a-th floating radiator 210a, and the distance from the upper surface of the board 100 to the upper surface of the 2a-th body 221a of the 2a-th floating radiator 220a may be different from each other.

[0124] The 1a-th antenna element 110a can radiate a first electromagnetic wave. For example, the first electromagnetic wave can be radiated from the 1a-th antenna element 110a along the x-axis, y-axis, and z-axis. The component of the first electromagnetic wave radiated along the x-axis can induce an electromagnetic field in the 1a-th floating radiator 210a and the 2a-th floating radiator 220a. For example, the 1a-th floating radiator 210a can re-radiate an electromagnetic wave based on the first electromagnetic wave. Furthermore, the 2a-th floating radiator 220a can re-radiate an electromagnetic wave based on the first electromagnetic wave.

[0125] For example, an electromagnetic field may be induced in the 1a-th floating radiator 210a by the first electromagnetic wave radiated from the 1a-th antenna element 110a. The 1a-th floating radiator 210a may radiate a second electromagnetic wave through the induced electromagnetic field.

[0126] An electromagnetic field may be induced in the 2a-th floating radiator 220a by the first electromagnetic wave radiated from the 1a-th antenna element 110a. The 2a-th floating radiator 220a may radiate a second electromagnetic wave through the induced electromagnetic field.

[0127] Figure 7 is a conceptual diagram illustrating current flow in an antenna module of an electronic device according to an embodiment of the present disclosure.

[0128] Reference Figure 7 , in the antenna module 11 , a plurality of floating radiators 220 a to 220 d may be electromagnetically coupled to the 1a-th antenna element 110 a .

[0129] For example, an electromagnetic field may be induced in each of the plurality of floating radiators 220a to 220d by the first electromagnetic wave radiated from the 1a-th antenna element 110a. Each of the plurality of floating radiators 220a to 220d, in which the electromagnetic field is induced by the first electromagnetic wave, may radiate a second electromagnetic wave through the electromagnetic field.

[0130] For example, the 1a-th floating radiator 220a may radiate a second electromagnetic wave by induced electromagnetic field from the 1a-th antenna element 110a. The 1b-th floating radiator 220b may radiate a second electromagnetic wave by induced electromagnetic field from the 1a-th antenna element 110a. The 1c-th floating radiator 220c may radiate a second electromagnetic wave by induced electromagnetic field from the 1a-th antenna element 110a. The 1d-th floating radiator 220d may radiate a second electromagnetic wave by induced electromagnetic field from the 1a-th antenna element 110a.

[0131] Figure 8 is a conceptual diagram illustrating a current flow in at least one floating radiator among a plurality of floating radiators of an antenna module of an electronic device according to an embodiment of the present disclosure.

[0132] Reference Figure 8 At least one of the plurality of floating radiators 210a to 250c may be designed in a wavelength ring manner. For example, the second-a floating radiator 220a may be designed in a wavelength ring manner. The second-a floating radiator 220a designed in a wavelength ring manner may function as a radiator.

[0133] For example, the horizontal or vertical length d of the 2a-th floating radiator 220a may be determined based on the length λ of the wavelength of the first electromagnetic wave radiated from the 1a-th antenna element 110a. For example, the horizontal or vertical length d of the 2a-th floating radiator 220a may be ¼ of the length λ of the wavelength of the first electromagnetic wave radiated from the 1a-th antenna element 110a. For example, the total length d*4 of the 2a-th floating radiator 220a may be the same as the length λ of the wavelength of the first electromagnetic wave radiated from the 1a-th antenna element 110a.

[0134] For example, with reference to the upper surface of antenna element 110a (1a), the polarization of the first electromagnetic wave radiated from antenna element 110a (1a) may be in the z-axis direction or close to the z-axis direction. In this case, the horizontal component of the current in the electromagnetic field induced in floating radiator 220a (2a), which has a horizontal or vertical length of λ / 4, can be canceled by mutual interference between the upper and lower surfaces of floating radiator 220a (2a). Therefore, the horizontal component of the current in the electromagnetic field induced in floating radiator 220a (2a) can be canceled, and only the vertical component can exist.

[0135] For example, the direction of the current flowing through the 1a-th antenna element 110a may be the same as or similar to the direction of the current flowing through the 2a-th floating radiator 220a. For example, since the plurality of floating radiators 210a to 250c and the plurality of antenna elements 110a to 140c have the same or similar current directions, the antenna module 11 may have a wider aperture.

[0136] The shape and size of each of the plurality of floating radiators 210a to 250j may be different from Figures 9 to 13 At least one of the floating radiators has the same or similar shape and size.

For example, the imaginary part of the inductance value of each of the plurality of inductors 511 to 514 and the imaginary part of the capacitance value of the capacitor 520 may be determined according to at least one of the horizontal length w9, the vertical length d9, and the line width w'9 of the floating radiator 900.

[0141] The direction of the second electromagnetic wave radiated from the floating radiator 900 may be based on Figure 5 The imaginary part of the factor value of each of the plurality of inductors 511 to 514 and the capacitor 520 is determined. For example, the direction of the second electromagnetic wave radiated from the floating radiator 900 may be determined based on at least one of the horizontal length w9, the vertical length d9, and the line width w'9 of the floating radiator 900. At least one of the horizontal length w9, the vertical length d9, and the line width w'9 of the floating radiator 900 may be determined so that the radiation direction of the second electromagnetic wave radiated from the floating radiator 900 is the same as the radiation direction of the first electromagnetic wave radiated from the 1a-th antenna element 110a.
