Description

[0001] This application is a divisional application of the patent application filed on January 15, 2021, with application number 202180009612.5, entitled "Antenna Module Including a Floating Radiator in a Communication System and Electronic Device Including the Same". Technical Field

[0002] This disclosure relates to communication systems. More specifically, this disclosure relates to an antenna module comprising a plurality of floating radiators and an electronic device comprising the antenna module. Background Technology

[0003] To meet the increasing demand for wireless data traffic since the deployment of fourth-generation (4G) communication systems, efforts have been made to develop improved fifth-generation (5G) or pre-5G communication systems. Therefore, 5G or pre-5G communication systems are also referred to as "super-4G networks" or "post-Long Term Evolution (LTE) systems." 5G communication systems are considered to be implemented in higher frequency (millimeter wave) bands (e.g., the 60GHz band), thereby achieving higher data rates. To reduce radio wave propagation loss and increase transmission distance, beamforming, massive MIMO, full-dimensional MIMO (FD-MIMO), array antennas, analog beamforming, and massive MIMO technologies have been discussed in 5G communication systems. Furthermore, in 5G communication systems, system network improvements are being developed based on advanced small cells, cloud radio access networks (RAN), ultra-dense networks, device-to-device (D2D) communication, wireless backhaul, mobile networks, cooperative communication, coordinated multipoint (CoMP), and receiver interference cancellation. In 5G systems, hybrid frequency shift keying (FSK), quadrature amplitude modulation (QAM) and sliding window superposition coding (SWSC) have been developed as advanced coding and modulation (ACM), as well as filter bank multicarrier (FBMC), non-orthogonal multiple access (NOMA) and sparse code multiple access (SCMA) as advanced access technologies.

[0004] The Internet (a human-centric network of connections in which 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 technology and big data processing technology with connections to cloud servers. With technological elements such as sensing technology, wired / wireless communication and network infrastructure, service interface technology, and security technology becoming necessary for IoT implementation, sensor networks, machine-to-machine (M2M) communication, and machine-type communication (MTC) have recently been explored. Such an IoT environment can provide intelligent Internet technology services, creating 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, IoT can be applied to a wide range of fields, including smart homes, smart buildings, smart cities, smart or connected cars, smart grids, healthcare, smart appliances, and advanced medical services.

[0005] Consistent with this, various attempts have been made to apply 5G communication systems to IoT networks. For example, technologies such as sensor networks, machine-type communication (MTC), and machine-to-machine (M2M) communication can be implemented using beamforming, MIMO, and array antennas. Cloud radio access networks (RAN), as an application of the aforementioned big data processing technologies, can also be considered an example of the convergence between 5G and IoT technologies.

[0006] The above information is presented as background information only to aid in understanding this disclosure. No determination is made, and no assertion is made, regarding whether any of the above content can be used as prior art with respect to this disclosure. Summary of the Invention

[0062] Figure 1 This is a block diagram illustrating an electronic device in a network environment according to an embodiment of the present disclosure.

[0063] Reference Figure 1 In a network environment, electronic device 10 can communicate with any other electronic device (not shown) or server (not shown) via a network (e.g., a wired or wireless communication network). For example, electronic device 10 can be a base station, and other electronic devices can be terminals.

[0064] 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 these 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 these components may be integrated into a single element.

[0065] The processor 13 can control at least one other component (e.g., hardware or software component) connected to the processor 13, such as the electronic device 10, and can perform various data processing or calculations. According to one embodiment, as at least part of the data processing or calculation, the processor 13 can store commands or data received from another component (e.g., communication module 12) in memory 14, process the commands or data stored in memory 14, and store the resulting data in memory 14.

[0066] The memory 14 can store various data used by at least one component of the electronic device 10. This data may include, for example, software and input or output data for commands associated with it.

Communication module 12 may include one or more communication processors, which can operate independently of processor 13 and support wired or wireless communication. According to another embodiment, communication module 12 can communicate with any other electronic device or server via traditional cellular networks, 5G networks, next-generation communication networks, the Internet, or computer networks (e.g., LANs or WANs). These various types of communication modules can be implemented as a single component (e.g., a single chip) or as multiple components (e.g., multiple chips) that are separate from each other.

[0069] 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, communication module 12 can support ultra-high frequency (millimeter-wave) bands to achieve higher data rates. Communication module 12 can support various technologies used to ensure performance in the ultra-high frequency band, such as beamforming, massive MIMO, full-dimensional MIMO (FD-MIMO), array antennas, analog beamforming, and massive antenna technology. Communication module 12 supports various requirements specified for electronic device 10, any other electronic device, or network system.

[0070] Antenna module 11 can transmit signals or power to or from the outside of electronic device 10 (e.g., any other electronic device). According to another embodiment, antenna module 11 may include an antenna comprising a radiating element made of conductive material or conductive patterns formed on a substrate (e.g., a PCB). According to another embodiment, antenna module 11 may include multiple antennas. In such a case, at least one antenna suitable for a communication scheme used in a network can be selected, for example, by communication module 12 from the multiple antennas. Signals or power can then be transmitted or received between communication module 12 and any other external electronic device via the selected at least one antenna. According to some embodiments, additional components besides the radiating element (e.g., a radio frequency integrated circuit (RFIC)) may be additionally formed as part of antenna module 11.

[0071] According to various embodiments, antenna module 11 can 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., the lower surface) of the printed circuit board and capable of supporting a specified high-frequency band (e.g., millimeter-wave band), and a plurality of antennas (e.g., array antennas) disposed on or adjacent to a second surface (e.g., the upper or side surface) of the printed circuit board and capable of transmitting or receiving signals in the specified high-frequency band.

[0072] At least some of the aforementioned components can be interconnected and transmit signals (e.g., commands or data) between them via peripheral communication schemes (e.g., bus, general purpose input and output (GPIO), serial peripheral interface (SPI), or mobile industrial processor interface (MIPI)).

[0073] According to another embodiment, commands or data can be sent or received between electronic device 10 and any other external electronic device via a server connected to a network. The other external electronic device can be a device of the same or different type as electronic device 10. According to another embodiment, all or some of the operations to be performed at electronic device 10 can be performed at the other external electronic device. For example, if electronic device 10 is required to perform a function or service automatically or in response to a request from a user or another device, instead of performing that function or service, or in addition to performing that function or service, electronic device 10 can request one or more other external electronic devices to perform at least a portion of that function or service. The one or more other external electronic devices receiving the request can perform at least a portion of the requested function or service, or additional functions or services related to the request, and transmit the result of the execution to electronic device 10. Electronic device 10 can provide the result as at least part of a response to the request, with or without further processing of the result. For this purpose, cloud computing, distributed computing, mobile edge computing (MEC), or client-server computing technologies can be used, for example. Electronic device 10 can use distributed computing or MEC to provide, for example, ultra-low latency services. In other implementations, the other external electronic device may include an Internet of Things (IoT) device.

[0075] It should be understood that the various embodiments of this disclosure and the terminology used therein are not intended to limit the technical features set forth herein to a particular embodiment, but rather to include various variations, equivalents, or alternatives to the respective embodiments. Regarding the description of the drawings, similar reference numerals may be used to denote similar or related elements. The singular form of a noun corresponding to an item may include one or more of that item 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,” “first,” and “second” may be used simply to distinguish the corresponding element from another and do not limit these elements in other respects (e.g., importance or order). It will be understood that, with or without the terms “operably” or “communically”, if an element (e.g., the first element) is referred to as being “connected” to or “linked” to another element (e.g., the second element), or “connected” to or “connected” to another element (e.g., the second element), this means that the element can be directly (e.g., wired), wirelessly, or via a third element to or be connected to the other element.

[0076] As used herein, the term "module" can include units implemented in hardware, software, or firmware, and can be used interchangeably with other terms such as "logic," "logic block," "component," or "circuit." A "module" can be the smallest unit, or a portion thereof, of a single integrated component suitable for performing one or more functions. For example, according to another embodiment, a "module" can be implemented in the form of an application-specific integrated circuit (ASIC).

[0077] The various implementations described herein can be implemented as software, which includes one or more instructions stored in a storage medium (e.g., memory 14) readable by a machine (e.g., electronic device 10). For example, a processor (e.g., processor 13) of the machine (e.g., electronic device 10) can invoke 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 invoked at least one instruction. 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" simply 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 stored semi-permanently in the storage medium and data being temporarily stored in the storage medium.

[0078] According to another embodiment, the methods according to various embodiments of this disclosure can be included and provided in a computer program product. The computer program product can be traded as a product between a seller and a buyer. The computer program product can be distributed in the form of a machine-readable storage medium (e.g., an optical disc read-only memory (CD-ROM)) or via an app store (e.g., the Play Store). TM Online distribution (e.g., downloading or uploading) or direct distribution between two user devices (e.g., smartphones). If distributed online, at least a portion of the computer program product may be temporarily generated or at least temporarily stored in a machine-readable storage medium, such as the memory of a manufacturer's server, an app store's server, or a relay server.

[0079] According to various embodiments, each of the above-described elements (e.g., a module or program) may comprise a single entity or multiple entities, and some of these multiple entities may be separately located within any other element. According to various embodiments, one or more of the above-described elements may be omitted, or one or more other elements may be added. Optionally or additionally, multiple elements (e.g., modules or programs) may be integrated into a single element. In such a case, according to various embodiments, the integrated elements may still perform one or more functions of each of the multiple elements in the same or similar manner as they were performed by their corresponding elements among the multiple elements prior to integration. According to various embodiments, operations performed by a module, program, or other element may be performed sequentially, in parallel, repeatedly, or heuristically, or one or more of the operations may be performed in a different order or omitted, or one or more other operations may be added.

[0080] Figure 2This is a graph showing the antenna gain of an antenna module of an electronic device according to an embodiment of the present disclosure.

[0081] Reference Figure 2 In the antenna gain curve 20 of the electromagnetic wave radiated from the antenna module 11 of the electronic device 10, the values ​​21 in the forward direction and 22 and 23 in the lateral direction can be different from each other. The lateral ratio of the antenna can be defined as the difference between the antenna gain value 21 in the forward direction and the antenna gain value 21 or 22 in the lateral direction of the electromagnetic wave radiated from the antenna module 11.

[0082] 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 another antenna array located on the side surface of said one antenna array can be reduced. For example, when the lateral ratio of each of the multiple antenna arrays of antenna module 11 decreases, the mutual influence of the multiple antenna arrays can be reduced.

[0083] The antenna module 11 of the electronic device 10 according to various embodiments can have a structure that reduces the lateral ratio. For example, the structure of the antenna module 11 can be as follows: Figure 3 As shown.

[0102] The fourth floating radiators 240a to 240j can be disposed on the upper surface of the plate 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 can be disposed to the right of the third antenna elements 130a to 130c. The fourth floating radiators 240a to 240j can be spaced apart from the third antenna elements 130a to 130c by a predetermined distance. The fourth floating radiators 240a to 240j can be disposed to the left of the fourth antenna elements 140a to 140c. The fourth floating radiators 240a to 240j can be spaced apart from the fourth antenna elements 140a to 140c by a predetermined distance.

[0103] The fifth floating radiators 250a to 250j can be disposed on the upper surface of the plate 100 to the left of the fourth antenna elements 140a to 140c. The fifth floating radiators 250a to 250j can be spaced apart from the fourth antenna elements 140a to 140c by a predetermined distance.

[0104] The directivity of the beam radiated from antenna module 11 can be proportional to the width of the aperture of antenna module 11 radiating the beam. For example, as the aperture of antenna module 11 increases, the width of the beam radiated from antenna module 11 can decrease.

[0105] The antenna module 11 can increase its aperture using the plurality of floating radiators 210a to 250c. That is, the antenna module 11 can decrease the width of the beam radiated from it using the plurality of floating radiators 210a to 250c. Therefore, the antenna module 11 can increase the directivity of the beam radiated from it using the plurality of floating radiators 210a to 250c.

[0106] Furthermore, the antenna module 11 can reduce surface waves caused by electromagnetic waves radiated from the multiple antenna elements 110a to 140c through the multiple floating radiators 210a to 250c.

The first floating radiator 210a can be positioned on the plate 100 at a predetermined distance d from the left side of the first antenna element 110a. The upper surface of the first floating radiator 210a can be spaced apart from the upper surface of the plate 100 by a predetermined distance h2. The horizontal width w of the first floating radiator 210a can have a predetermined size.

[0109] Reference Figure 5 The multiple floating radiators 210a to 210e and 220a to 220e of the antenna module 11 can be electromagnetically coupled to multiple antenna elements 110a to 110b.

[0110] For example, multiple antenna elements 110a to 110b can radiate a first electromagnetic wave. The first electromagnetic wave radiated from the multiple antenna elements 110a to 110b can induce an electromagnetic field in multiple floating radiators 210a to 210e and 220a to 220e. For example, due to the electromagnetic field induced by the first electromagnetic wave, the multiple floating radiators 210a to 210e and 220a to 220e can radiate a second electromagnetic wave.

[0111] Due to the multiple 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 a first electromagnetic wave and a second electromagnetic wave. For example, the width of the beam radiated from the antenna module 11 can be narrowed by using the first electromagnetic wave and the second electromagnetic wave.

[0112] Multiple floating radiators 210a to 210e and 220a to 220e can prevent the first electromagnetic wave radiated from the multiple antenna elements 110a to 110b from propagating to the surface of the antenna module 11. For example, the multiple floating radiators 210a to 210e and 220a to 220e can reduce the effect of surface waves caused by the first electromagnetic wave.

[0113] Multiple floating radiators 210a to 210e and 220a to 220e may have a capacitance factor and an inductance factor. For example, the second 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 floating radiator 220a may include multiple inductors 511 to 514 and a capacitor 520. A first terminal of the first inductor 511 may be electrically connected to a first terminal of the fourth inductor 514. A second terminal of the first inductor 511 may be electrically connected to a first terminal of the second inductor 512. A second terminal of the second inductor 512 may be electrically connected to a first terminal of the third inductor 513. A second terminal of the third inductor 513 may be electrically connected to a first terminal of the fourth inductor 514. One end of the capacitor 520 may be electrically connected to a third terminal of the first inductor 511. One end of capacitor 520 can be electrically connected to the third end of third inductor 513.

[0114] The capacitance factor and inductance factor of each of the plurality of floating radiators 210a to 210e and 220a to 220e can be determined based on at least one of the horizontal length, vertical length, thickness, and linewidth 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 capacitor 520 can be determined based on at least one of the horizontal length, vertical length, thickness, and linewidth of the second floating radiator 220a. For example, the imaginary part of the factor value of each of the plurality of inductors 511 to 514 and capacitor 520 can be determined based on at least one of the horizontal length, vertical length, thickness, and linewidth of the second 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 capacitor 520 can be determined based on at least one of the horizontal length, vertical length, thickness, and linewidth of the second floating radiator 220a.

[0115] The phase of the second electromagnetic wave radiated from the second floating radiator 220a can be determined based on the imaginary part of the factor values ​​of each of the plurality of inductors 511 to 514 and capacitor 520. That is, the phase of the second electromagnetic wave radiated from the second floating radiator 220a can be determined based on at least one of the horizontal length, vertical length, thickness, and linewidth of the second floating radiator 220a. At least one of the horizontal length, vertical length, thickness, and linewidth of the second floating radiator 220a can be determined such that the phase of the second electromagnetic wave is the same as the phase of the first electromagnetic wave.

[0117] Reference Figure 6 The upper surface of the main body 111a of the first antenna element 110a of the antenna module 11 can be spaced apart from the upper surface of the plate 100 by a predetermined distance h1.

[0118] The first-a floating radiator 210a may include a first-a main body 211a and a first-a support member 212a. For example, the first-a support member 212a may be disposed on the upper surface of the plate 100. Optionally, the first-a support member 212a may be integrally injection molded with the plate 100.

[0119] The first body 211a can be disposed on the upper surface of the first support member 212a. The first body 211a can be disposed on the plate 100 at a predetermined distance d from the left side of the first antenna element 110a. The upper surface of the first body 211a can be spaced from the upper surface of the plate 100 at a predetermined distance h2.

[0120] Figure 5 The factor value of each of the plurality of inductors 511 to 514 and capacitor 520 can be determined based on the thickness t of the first body 211a and the length w of its horizontal or vertical width. For example, the imaginary part of the factor value of each of the plurality of inductors 511 to 514 and capacitor 520 can be determined based on at least one of the thickness t of the first body 211a and the length w of its horizontal or vertical width. 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 capacitor 520 can be determined based on at least one of the thickness t of the first body 211a and the length w of its horizontal or vertical width.

[0121] The direction of the second electromagnetic wave radiated from the first floating radiator 210a can be based on Figure 5The phase of the second electromagnetic wave radiated from the first floating radiator 210a is determined by the imaginary part of the factor value of each of the multiple inductors 511 to 514 and capacitor 520. That is, the phase of the second electromagnetic wave radiated from the first floating radiator 210a can be determined based on at least one of the thickness t of the first body 211a and the length w of its horizontal or vertical width. At least one of the thickness t of the first body 211a and the length w of its horizontal or vertical width can be determined such that the phase of the second electromagnetic wave is the same as the radiation direction of the first electromagnetic wave.

[0122] The second floating radiator 220a may include a second body 221a and a second support member 222a. For example, the second support member 222a may be disposed on the upper surface of the plate 100. Optionally, the second support member 222a may be integrally injection molded with the plate 100.

[0123] The second body 221a can be disposed on the upper surface of the second support member 222a. The second body 221a can be disposed on the plate 100 at a predetermined distance d from the right side of the first antenna element 110a. The upper surface of the second body 221a can be spaced apart from the upper surface of the plate 100 at a predetermined distance.

[0124] The distances h1 from the upper surface of plate 100 to the upper surface of the body 111a of the first a antenna element 110a, h2 from the upper surface of plate 100 to the upper surface of the first a body 211a of the first a floating radiator 210a, and h2 from the upper surface of plate 100 to the upper surface of the second body 221a of the second a floating radiator 220a can be the same or similar. Optionally, the distances h1 from the upper surface of plate 100 to the upper surface of the body 111a of the first a antenna element 110a, h2 from the upper surface of plate 100 to the upper surface of the first a body 211a of the first a floating radiator 210a, and h2 from the upper surface of plate 100 to the upper surface of the second body 221a of the second a floating radiator 220a can be different from each other.

[0125] The first antenna element 110a can radiate a first electromagnetic wave. For example, the first electromagnetic wave can be radiated from the first antenna element 110a along the x-axis, y-axis, and z-axis. The component radiated from the first electromagnetic wave along the x-axis can induce electromagnetic fields in the first floating radiator 210a and the second floating radiator 220a. For example, the first floating radiator 210a can re-radiate electromagnetic waves based on the first electromagnetic wave. Furthermore, the second floating radiator 220a can re-radiate electromagnetic waves based on the first electromagnetic wave.

[0126] For example, an electromagnetic field can be induced in the first-a floating radiator 210a by a first electromagnetic wave radiated from the first-a antenna element 110a. The first-a floating radiator 210a can then radiate a second electromagnetic wave through the induced electromagnetic field.

[0127] An electromagnetic field can be induced in the second-a floating radiator 220a by a first electromagnetic wave radiated from the first-a antenna element 110a. The second-a floating radiator 220a can radiate a second electromagnetic wave through the induced electromagnetic field.

[0128] Figure 7 This is a conceptual diagram illustrating the current flow in an antenna module of an electronic device according to an embodiment of the present disclosure.

[0129] Reference Figure 7 In antenna module 11, multiple floating radiators 220a to 220d can be electromagnetically coupled to antenna element 110a.

[0130] For example, an electromagnetic field can be induced in each of the plurality of floating radiators 220a to 220d by a first electromagnetic wave radiated from the first antenna element 110a. Each of the plurality of floating radiators 220a to 220d that induced the electromagnetic field by the first electromagnetic wave can radiate a second electromagnetic wave through that electromagnetic field.

[0131] For example, the first-a floating radiator 220a can radiate a second electromagnetic wave through the electromagnetic field induced from the first-a antenna element 110a. The first-b floating radiator 220b can radiate a second electromagnetic wave through the electromagnetic field induced from the first-a antenna element 110a. The first-c floating radiator 220c can radiate a second electromagnetic wave through the electromagnetic field induced from the first-a antenna element 110a. The first-d floating radiator 220d can radiate a second electromagnetic wave through the electromagnetic field induced from the first-a antenna element 110a.

[0132] Figure 8 This is a conceptual diagram illustrating the current flow in at least one of a plurality of floating radiators of an antenna module of an electronic device according to an embodiment of the present disclosure.

[0133] Reference Figure 8 At least one of the multiple floating radiators 210a to 250c can be designed in a wavelength loop configuration. For example, the second floating radiator 220a can be designed in a wavelength loop configuration. The second floating radiator 220a designed in a wavelength loop configuration can operate as a radiator.

[0134] For example, the horizontal or vertical length d of the second floating radiator 220a can be determined based on the wavelength λ of the first electromagnetic wave radiated from the first antenna element 110a. For example, the horizontal or vertical length d of the second floating radiator 220a can be 1 / 4 of the wavelength λ of the first electromagnetic wave radiated from the first antenna element 110a. For example, the total length d*4 of the second floating radiator 220a can be the same as the wavelength λ of the first electromagnetic wave radiated from the first antenna element 110a.

[0135] For example, referring to the upper surface of the first antenna element 110a, the polarization of the first electromagnetic wave radiated from the first antenna element 110a can be in or near the z-axis direction. In this case, the horizontal component of the current in the electromagnetic field induced in the second floating radiator 220a with a horizontal or vertical length of λ / 4 can be eliminated by the mutual interference between the upper and lower surfaces of the second floating radiator 220a. Therefore, in the electromagnetic field induced in the second floating radiator 220a, the horizontal component of the current can be eliminated, and only the vertical component can exist.

[0136] For example, the current direction of the first antenna element 110a can be the same as or similar to the current direction flowing through the second floating radiator 220a. For example, since the multiple floating radiators 210a to 250c and the multiple antenna elements 110a to 140c have the same or similar current directions, the antenna module 11 can have a wider aperture.

For example, the imaginary part of the factor value of each of the plurality of inductors 511 to 514 and capacitor 520 can be determined based on at least one of the horizontal length w9, vertical length d9, and linewidth w'9 of the floating radiator 900. 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 capacitor 520 can be determined based on at least one of the horizontal length w9, vertical length d9, and linewidth w'9 of the floating radiator 900.
