Title: Antenna and electronic device including the same

Description:
TECHNICAL FIELD 
     Various embodiments provide an antenna and an electronic device including the same. 
     BACKGROUND ART 
     One of current trends in developing electronic devices to meet customer&#39;s demands is slimming a device body, that is, reducing a thickness of the electronic device. In addition, such electronic devices are being developed to increase their stiffness, strengthen their design aspects, and differentiate their functional features. 
     Realizing a slim electronic device needs efficiently disposing a plurality of electronic components in the inner space of the electronic device. However, if such electronic components, even though efficiently disposed, have functions not properly manifested, the quality of the electronic device may be deteriorated. Thus, the electronic device is required to meet both conditions. 
     DETAILED DESCRIPTION OF INVENTION 
     Technical Problem 
     According to next-generation wireless communication Portable electronic devices such as a mobile terminal, a mobile communication terminal, or a smart phone are capable of communicating with a remotely located, external electronic device through a wireless communication circuit and at least one antenna and also implementing connectivity with a nearby external device using a designated network. For example, the electronic device may have a plurality of antennas (e.g., antenna structures) so as to provide different wireless communication functions in various frequency bands. 
     The plurality of antennas may be disposed to be spaced apart from a printed circuit board (PCB) disposed in the inner space of the electronic device, and may be electrically connected to the PCB through an electrical connection means such as a flexible substrate. 
     However, as the electronic device becomes slim, a separation distance between adjacent antennas is gradually narrowing, and the radiation performance of the antennas may be deteriorated due to mutual interference. 
     Solution to Problem 
     Various embodiments of the present invention may provide an electronic device including an antenna. 
     Various embodiments of the present invention may provide an electronic device that includes antennas having improved radiation performance despite being disposed in the same mounting space. 
     According to various embodiments, an electronic device may include a housing having an inner space, a printed circuit board (PCB) disposed in the inner space of the housing, a first antenna structure disposed at a position spaced apart from the PCB, and transmitting and/or receiving a radio signal in a first frequency band, at least one second antenna structure disposed at a position spaced apart from the PCB, and transmitting and/or receiving a radio signal in a second frequency band different from the first frequency band, and a flexible substrate electrically connecting the PCB and the first antenna structure. The flexible substrate may include a first connecting portion electrically connected to the PCB, an interconnecting portion extended from the first connecting portion to the first antenna structure, at least one branch portion branched from at least a part of the interconnecting portion, and extended to the at least one second antenna structure, at least one first conductive path disposed in the interconnecting portion, and electrically connecting the first connecting portion and the first antenna structure, and at least one second conductive path disposed in the interconnecting portion and the at least one branch portion, and electrically connecting the first connecting portion and the at least one second antenna structure. 
     Various respective aspects and features of the invention are defined in the appended claims. Combinations of features from the dependent claims may be combined with features of the independent claims as appropriate and not merely as explicitly set out in the claims. 
     Furthermore, one or more selected features of any one embodiment described in this disclosure may be combined with one or more selected features of any other embodiment described herein, provided that the alternative combination of features at least partially alleviates the one or more technical problem discussed in this disclosure or at least partially alleviates a technical problem discernible by the skilled person from this disclosure and further provided that the particular combination or permutation of embodiment features thus formed would not be understood by the skilled person to be incompatible. 
     Two or more physically distinct components in any described example implementation of this disclosure may alternatively be integrated into a single component where possible, provided that the same function is performed by the single component thus formed. Conversely, a single component of any embodiment described in this disclosure may alternatively be implemented as two or more distinct components to achieve the same function, where appropriate. 
     It is an aim of certain embodiments of the invention to solve, mitigate or obviate, at least partly, at least one of the problems and/or disadvantages associated with the prior art. Certain embodiments aim to provide at least one of the advantages described below. 
     Advantageous Effects of Invention 
     An electronic device according to exemplary In the electronic device according to various embodiments of the present invention, at least some antennas are spaced apart from other antennas by using at least a portion of a flexible substrate. It is therefore possible to ensure a sufficient separation distance between adjacent antennas, improve the radiation performance of antennas, and contribute to slimming of the electronic device.

     The interface  177  may support one or more specified protocols to be used for the electronic device  101  to be coupled with the external electronic device (e.g., the electronic device  102 ) directly (e.g., wiredly) or wirelessly. The interface  177  may include, for example, a high definition multimedia interface (HDMI), a universal serial bus (USB) interface, a secure digital (SD) card interface, or an audio interface. 
     A connection terminal  178  may include a connector via which the electronic device  101  may be physically connected with the external electronic device (e.g., the electronic device  102 ). The connection terminal  178  may include, for example, a HDMI connector, a USB connector, a SD card connector, or an audio connector (e.g., a headphone connector). 
     The haptic module  179  may convert an electrical signal into a mechanical stimulus (e.g., a vibration or a movement) or electrical stimulus which may be recognized by a user via his tactile sensation or kinesthetic sensation. The haptic module  179  may include, for example, a motor, a piezoelectric element, or an electric stimulator. 
     The camera module  180  may capture an image or moving images. The camera module  180  may include one or more lenses, image sensors, image signal processors, or flashes. 
     The power management module  188  may manage power supplied to the electronic device  101 . The power management module  188  may be implemented as at least part of, for example, a power management integrated circuit (PMIC). 
     The battery  189  may supply power to at least one component of the electronic device  101 . The battery  189  may include, for example, a primary cell which is not rechargeable, a secondary cell which is rechargeable, or a fuel cell. 
     The communication module  190  may support establishing a direct (e.g., wired) communication channel or a wireless communication channel between the electronic device  101  and the external electronic device (e.g., the electronic device  102 , the electronic device  104 , or the server  108 ) and performing communication via the established communication channel. The communication module  190  may include one or more communication processors that are operable independently from the processor  120  (e.g., the AP) and supports a direct (e.g., wired) communication or a wireless communication. The communication module  190  may include a wireless communication module  192  (e.g., a cellular communication module, a short-range wireless communication module, or a global navigation satellite system (GNSS) communication module) or a wired communication module  194  (e.g., a local area network (LAN) communication module or a power line communication (PLC) module). A corresponding one of these communication modules may communicate with the external electronic device via the first network  198  (e.g., a short-range communication network, such as Bluetooth™, wireless-fidelity (Wi-Fi) direct, or infrared data association (IrDA)) or the second network  199  (e.g., a long-range communication network, such as a cellular network, the Internet, or a computer network (e.g., LAN or wide area network (WAN)). These various types of communication modules may be implemented as a single component (e.g., a single chip), or may be implemented as multi components (e.g., multi chips) separate from each other. The wireless communication module  192  may identify and authenticate the electronic device  101  in a communication network, such as the first network  198  or the second network  199 , using subscriber information (e.g., international mobile subscriber identity (IMSI)) stored in the SIM  196 .

The antenna module  197  may include an antenna including a radiating element composed of a conductive material or a conductive pattern formed in or on a substrate (e.g., a printed circuit board (PCB)). The antenna module  197  may include a plurality of antennas. In such a case, at least one antenna appropriate for a communication scheme used in the communication network, such as the first network  198  or the second network  199 , may be selected, for example, by the communication module  190  (e.g., the wireless communication module  192 ) from the plurality of antennas. The signal or the power may then be transmitted or received between the communication module  190  and the external electronic device via the selected at least one antenna. Another component (e.g., a radio frequency integrated circuit (RFIC)) other than the radiating element may be additionally formed as part of the antenna module  197 . 
     At least some of the above-described components may be coupled mutually and communicate signals (e.g., commands or data) therebetween via an inter-peripheral communication scheme (e.g., a bus, general purpose input and output (GPIO), serial peripheral interface (SPI), or mobile industry processor interface (MIPI)). 
     Commands or data may be transmitted or received between the electronic device  101  and the external electronic device  104  via the server  108  coupled with the second network  199 . Each of the electronic devices  102  and  104  may be a device of a same type as, or a different type, from the electronic device  101 . All or some of operations to be executed at the electronic device  101  may be executed at one or more of the external electronic devices  102 ,  104 , or  108 . For example, if the electronic device  101  should perform a function or a service automatically, or in response to a request from a user or another device, the electronic device  101 , instead of, or in addition to, executing the function or the service, may request the one or more external electronic devices to perform at least part of the function or the service. The one or more external electronic devices receiving the request may perform the at least part of the function or the service requested, or an additional function or an additional service related to the request, and transfer an outcome of the performing to the electronic device  101 . The electronic device  101  may provide the outcome, with or without further processing of the outcome, as at least part of a reply to the request. To that end, a cloud computing, distributed computing, or client-server computing technology may be used, for example. 
     An electronic device according to an embodiment may be one of various types of electronic devices. The electronic device may include a portable communication device (e.g., a smart phone), a computer device, a portable multimedia device, a portable medical device, a camera, a wearable device, or a home appliance.

     The third RFIC  226  may convert a baseband signal generated by the second communication processor  214  to an RF signal (hereinafter, 5G Above6 RF signal) of a 5G Above6 band (e.g., about 6 GHz to about 60 GHz) to be used in the second cellular network  294  (e.g., 5G network). Upon reception, a 5G Above6 RF signal may be obtained from the second cellular network  294  (e.g., 5G network) through an antenna (e.g., the antenna  248 ) and be preprocessed through a third RFFE  236 . The third RFIC  226  may convert the preprocessed 5G Above6 RF signal to a baseband signal so as to be processed by the second communication processor  214 . According to one embodiment, the third RFFE  236  may be formed as part of the third RFIC  226 . 
     According to an embodiment, the electronic device  101  may include a fourth RFIC  228  separately from the third RFIC  226  or as at least part of the third RFIC  226 . In this case, the fourth RFIC  228  may convert a baseband signal generated by the second communication processor  214  to an RF signal (hereinafter, an intermediate frequency (IF) signal) of an intermediate frequency band (e.g., about 9 GHz to about 11 GHz) and transfer the IF signal to the third RFIC  226 . The third RFIC  226  may convert the IF signal to a 5G Above 6RF signal. Upon reception, the 5G Above 6RF signal may be received from the second cellular network  294  (e.g., a 5G network) through an antenna (e.g., the antenna  248 ) and be converted to an IF signal by the third RFIC  226 . The fourth RFIC  228  may convert an IF signal to a baseband signal so as to be processed by the second communication processor  214 . 
     According to one embodiment, the first RFIC  222  and the second RFIC  224  may be implemented into at least part of a single package or a single chip. According to one embodiment, the first RFFE  232  and the second RFFE  234  may be implemented into at least part of a single package or a single chip. According to one embodiment, at least one of the first antenna module  242  or the second antenna module  244  may be omitted or may be combined with another antenna module to process RF signals of a corresponding plurality of bands. 
     According to one embodiment, the third RFIC  226  and the antenna  248  may be disposed at the same substrate to form a third antenna module  246 . For example, the wireless communication module  192  or the processor  120  may be disposed at a first substrate (e.g., main PCB). In this case, the third RFIC  226  is disposed in a partial area (e.g., lower surface) of the first substrate and a separate second substrate (e.g., sub PCB), and the antenna  248  is disposed in another partial area (e.g., upper surface) thereof; thus, the third antenna module  246  may be formed. By disposing the third RFIC  226  and the antenna  248  in the same substrate, a length of a transmission line therebetween can be reduced. This may reduce, for example, a loss (e.g., attenuation) of a signal of a high frequency band (e.g., about 6 GHz to about 60 GHz) to be used in 5G network communication by a transmission line. Therefore, the electronic device  101  may improve a quality or speed of communication with the second cellular network  294  (e.g., 5G network). 
     According to one embodiment, the antenna  248  may be formed in an antenna array including a plurality of antenna elements that may be used for beamforming. In this case, the third RFIC  226  may include a plurality of phase shifters  238  corresponding to a plurality of antenna elements, for example, as part of the third RFFE  236 . Upon transmission, each of the plurality of phase shifters  238  may convert a phase of a 5G Above6 RF signal to be transmitted to the outside (e.g., a base station of a 5G network) of the electronic device  101  through a corresponding antenna element. Upon reception, each of the plurality of phase shifters  238  may convert a phase of the 5G Above6 RF signal received from the outside to the same phase or substantially the same phase through a corresponding antenna element. This enables transmission or reception through beamforming between the electronic device  101  and the outside. 
     The second cellular network  294  (e.g., 5G network) may operate (e.g., stand-alone (SA)) independently of the first cellular network  292  (e.g., legacy network) or may be operated (e.g., non-stand alone (NSA)) in connection with the first cellular network  292 . For example, the 5G network may have only an access network (e.g., 5G radio access network (RAN) or a next generation (NG) RAN and have no core network (e.g., next generation core (NGC)). In this case, after accessing to the access network of the 5G network, the electronic device  101  may access to an external network (e.g., Internet) under the control of a core network (e.g., an evolved packed core (EPC)) of the legacy network. Protocol information (e.g., LTE protocol information) for communication with a legacy network or protocol information (e.g., new radio (NR) protocol information) for communication with a 5G network may be stored in the memory  130  to be accessed by other components (e.g., the processor  120 , the first communication processor  212 , or the second communication processor  214 ).

In still another embodiment, the non-conductive member  522  may be insert-injected into the conductive member  521 . In yet another embodiment, the non-conductive member  522  may be structurally combined with the conductive member  521 . According to an embodiment, the lateral member  520  may include a support member  5211  (e.g., the first support member  3211  in  FIG.  3 C ), as a support means, extended partially into the inner space  5001 .
