Various embodiments of the present disclosure relate to an antenna and an electronic device comprising the same.
With the development of wireless communication technology, electronic devices (e.g., electronic devices for communication) have become ubiquitous in daily life, and this has led to an exponential increase in content consumption. The rapid increase in content consumption is causing network capacity to gradually reach its limit, and since the commercialization of the 4G (4th generation) communication system, communication systems (e.g., 5G (5th generation), pre-5G communication system, or new radio (NR)) that use high-frequency (e.g., mmWave) bands (e.g., 3 GHz to 300 GHz bands) to transmit and/or receive signals are being researched to meet the increasing demand for wireless data traffic.
The next-generation wireless communication technology can transmit and receive wireless signals using frequencies in the range of 3 GHz 100 GHz, and an efficient mounting structure and corresponding antenna structure (e.g., an antenna module) to overcome high free space losses from these relatively high frequency features and to increase the gain of the antenna are being developed. The antenna structure may include an array antenna in which various number of antenna elements (e.g., conductive patches and/or conductive patterns) are disposed at regular intervals. Such antenna elements may be disposed such that a beam pattern is formed in any one direction inside the electronic device. For example, the antenna structure may be disposed such that a beam pattern is formed toward at least a portion of the front surface, rear surface and/or side surface in the inner space of the electronic device.
The electronic device may include a conductive member (e.g., a metal member) disposed at least a portion of the housing and a non-conductive member (e.g., a polymer member) coupled to a conductive member for a rigidity reinforcement and a elegant appearance formation. Such a conductive member may be at least partially omitted in the portion facing the antenna structure disposed in the inner space of the electronic device, and the omitted portion may be replaced by a non-conductive member.
However, a conductive member located near the antenna structure and forming the boundary area by being combined with a non-conductive member may generate an eddy current or surface wave (e.g., trap current) because of its structural shape, and such an excitation current may be partially concentrated to the rear surface of the antenna structure, thereby degrading radiation performance (e.g., gain) in the front direction of the antenna structure.
To solve the problem of eddy currents (trap currents) caused by a conductive member being located near the antenna structure, the non-conductive member coupled with the conductive member may be extended to a position relatively far from the antenna structure. Unfortunately, this may cause a decrease in the rigidity of the electronic device.
Various embodiments of the present disclosure may provide an antenna configured to reduce radiation degradation through a support structure of the antenna structure that maintains rigidity and an electronic device comprising the same.
According to various embodiments, the electronic device may comprise: a housing comprising a conductive member and a non-conductive member coupled to the conductive member; an antenna structure disposed in the inner space of the housing, comprising a substrate that includes a first substrate surface facing a first direction, a second substrate surface facing a second direction opposite to the first substrate surface, and a substrate side surface surrounding a space between the first substrate surface and the second substrate surface, and at least one antenna element disposed to form a beam pattern in the first direction; a first support part disposed to at least partially correspond to the second substrate surface in the inner space of the housing; a conductive bracket comprising at least one conductive extension part disposed higher than the second substrate surface in a direction perpendicular to the first direction from the first support; and a wireless communication circuit configured to transmit and/or receive a radio signal in a frequency band specified through the at least one antenna element, and when the housing is viewed from the outside, the antenna structure may be disposed at a position overlapping at least partially with the non-conductive member.
The antenna structure according to an exemplary embodiment of the present disclosure may receive help to improve the radiation performance (e.g., gain) in a front direction by reducing a phenomenon in which the peripheral excitation current is concentrated to the rear surface of the antenna structure through at least one conductive extension part disposed higher than the antenna from the conductive bracket supporting the substrate.
In addition, various effects that are directly or indirectly identified through this document may be provided.
In connection with the description of the drawings, the same or similar reference numerals may be used for the same or similar elements.

The first communication processor 212 may include various processing circuitry and establish a communication channel of a band to be used for wireless communication with the first cellular network 292 and support legacy network communication through the established communication channel According to various embodiments, the first cellular network may be a legacy network including a second generation (2G), 3G, 4G, or long term evolution (LTE) network. The second communication processor 214 may include various processing circuitry and establish a communication channel corresponding to a designated band (e.g., about 6 GHz to about 60 GHz) of bands to be used for wireless communication with the second cellular network 294, and support 5G network communication through the established communication channel. According to various embodiments, the second cellular network 294 may be a 5G network defined in 3GPP. Additionally, according to an embodiment, the first communication processor 212 or the second communication processor 214 may establish a communication channel corresponding to another designated band (e.g., about 6 GHz or less) of bands to be used for wireless communication with the second cellular network 294 and support 5G network communication through the established communication channel. According to an embodiment, the first communication processor 212 and the second communication processor 214 may be implemented in a single chip or a single package. According to various embodiments, the first communication processor 212 or the second communication processor 214 may be formed in a single chip or a single package with the processor 120, the auxiliary processor 123, or the communication module 190.
Upon transmission, the first RFIC 222 may convert a baseband signal generated by the first communication processor 212 to a radio frequency (RF) signal of about 700 MHz to about 3 GHz used in the first cellular network 292 (e.g., legacy network). Upon reception, an RF signal may be obtained from the first cellular network 292 (e.g., legacy network) through an antenna (e.g., the first antenna module 242) and be preprocessed through an RFFE (e.g., the first RFFE 232). The first RFIC 222 may convert the preprocessed RF signal to a baseband signal so as to be processed by the first communication processor 212.
Upon transmission, the second RFIC 224 may convert a baseband signal generated by the first communication processor 212 or the second communication processor 214 to an RF signal (hereinafter, 5G Sub6 RF signal) of a Sub6 band (e.g., 6 GHz or less) to be used in the second cellular network 294 (e.g., 5G network). Upon reception, a 5G Sub6 RF signal may be obtained from the second cellular network 294 (e.g., 5G network) through an antenna (e.g., the second antenna module 244) and be pretreated through an RFFE (e.g., the second RFFE 234). The second RFIC 224 may convert the preprocessed 5G Sub6 RF signal to a baseband signal so as to be processed by a corresponding communication processor of the first communication processor 212 or the second communication processor 214.
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 the 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 an 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.

According to an 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 an 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 an 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 an 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 an 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).
