Description

TECHNICAL FIELD

The disclosure relates to an antenna and an electronic device including the same.

BACKGROUND ART

With the development of wireless communication technology, electronic devices (e.g., electronic devices for communication) are commonly used in daily life, and thus the use of contents is increasing exponentially. Due to the rapid increase in contents use, a network capacity is gradually reaching a limit thereof, and after the commercialization of 4th generation (4G) communication system, in order to meet the increasing demand for wireless traffic data, a communication system (e.g., 5th generation (5G), pre-5G communication system, or new radio (NR)) that transmits and/or receives a signal using a frequency of high-frequency (e.g., mmWave) bands (e.g., 3 GHz to 300 GHz bands) is being researched.

The above information is presented as background information only to assist with an understanding of the 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 regard to the disclosure.

DISCLOSURE

Technical Problem

Next-generation wireless communication technology may substantially transmit and receive wireless signals using a frequency in a range of 3 GHz to 100 GHz, and an efficient mounting structure for overcoming a high free space loss due to frequency characteristics and for increasing a gain of an antenna, and a new antenna structure (e.g., antenna module) corresponding thereto is being developed. The antenna structure may include an array antenna in which the various number of antenna elements (e.g., conductive patches and/or conductive patterns) are disposed at regular intervals in a dielectric structure (e.g., substrate). These antenna elements may be disposed to form a beam pattern in any one direction inside the electronic device. For example, the antenna structure may be disposed to form a beam pattern toward at least a portion of a front surface, a rear surface, and/or a side surface in an internal space of the electronic device.

In order to reinforce rigidity and form a beautiful appearance, the electronic device may include a conductive part (e.g., metal member) disposed in at least a portion of the housing and a non-conductive part (e.g., polymer member) coupled to the conductive part. The conductive part may be at least partially omitted in a portion facing an antenna structure disposed in the internal space of the electronic device, and the omitted portion may be replaced with the non-conductive part.

However, the conductive part disposed close to the antenna structure may be disposed to at least partially cover a radiation direction of a beam pattern of the antenna structure, and such a disposition structure may deteriorate a radiation performance of the antenna structure. In order to solve such a problem, the conductive part may be disposed at a position relatively far from the antenna structure, but this may cause a decrease in rigidity of the electronic device.

Aspects of the disclosure are to address at least the above-mentioned problems and/or disadvantages and to provide at least the advantages described below. Accordingly, an aspect of the disclosure is to provide an antenna and an electronic device including the same constituted to reduce radiation performance degradation through conductive additional structures disposed at a periphery of an antenna structure.

Another aspect of the disclosure is to provide an antenna and an electronic device including the same, which can help to reinforce rigidity of the electronic device by reducing radiation performance degradation even though a conductive part is disposed near an antenna structure.

Additional aspects will be set forth in part in the description which follows and, in part, will be apparent from the description, or may be learned by practice of the presented embodiments.

Advantageous Effects

An antenna structure according to an embodiment of the disclosure can reduce radiation performance degradation by expanding a beam width in a designated direction through a conductive dummy plate spaced apart at a specified interval from at least one antenna element in a radiation direction. Further, because the conductive part of the housing may be disposed near the antenna structure while reducing radiation performance degradation of the antenna structure by the conductive dummy plate, thereby helping to reinforce rigidity of the electronic device.

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 another embodiment, some sensor modules 304 may be arranged to perform their functions without being visually exposed through the front plate 302 in the internal space of the electronic device. For example, in this case, an area of the display 301 facing the sensor module may not require a perforated opening.

According to an embodiment, the first conductive dummy plate 610 may have substantially the same length L as that of the first conductive patch 510 when the housing (e.g., the housing 710 of FIG. 7B) is viewed from the outside and be disposed at a position overlapped with a center of the first conductive patch 510. According to an embodiment, the first conductive dummy plate 610 may be disposed to have a designated distance D from the first conductive patch 510. According to an embodiment, the designated distance D may include a range of about 0.01λ to 1λ. According to an embodiment, the designated distance D may include about 0.79 mm. According to an embodiment, a disposition structure of the second conductive dummy plate 620 with respect to the second conductive patch 520 may be substantially the same as that of the first conductive dummy plate 610 with respect to the first conductive patch 510.

According to various embodiments, as illustrated, the at least one conductive dummy plate 610 and 620 includes a first conductive dummy plate 610 and a second conductive dummy plate 620 disposed at positions corresponding to a first conductive patch 510 and a second conductive patch 510, respectively among the five conductive patches 510, 520, 530, 540, and 550, but the disclosure is not limited thereto. For example, the at least one conductive dummy plate may include one conductive dummy plate disposed at a position corresponding to any one of the plurality of conductive patches 510, 520, 530, 540 and 550. In some embodiments, the at least one conductive dummy plate may include a plurality of conductive dummy plates disposed at positions corresponding to all of the plurality of conductive patches 510, 520, 530, 540, and 550, respectively. In some embodiments, the at least one conductive dummy plate may be disposed symmetrically or asymmetrically to the left and the right at positions corresponding to some conductive patches among the plurality of conductive patches 510, 520, 530, 540, and 550. In some embodiments, the at least one conductive dummy plate 610 and 620 may be disposed to have a length in a direction perpendicular to the second polarization direction, for example, a direction (e.g., direction {circle around (2)}) perpendicular to the first plate surface 6101.

According to various embodiments, in a low frequency band (e.g., 28 GHz band) that may affect a radiation performance by the conductive part (e.g., the conductive part 721 of FIG. 7B) of the housing (e.g., the housing 710 of FIG. 7B), in order to prevent performance degradation of vertical polarization, the conductive dummy plates 610 and 620 may have a length in a direction (direction {circle around (3)}) perpendicular to the vertical polarization direction (direction {circle around (2)}) and be disposed so that the first plate surface 6101 faces in a direction (direction {circle around (2)}) perpendicular to the surface of the conductive patches 610 and 620.

According to embodiments of the disclosure, by extending a beam width to a portion of a direction in which the rear plate (e.g., a rear plate 740 of FIG. 7B) of the electronic device (e.g., the electronic device 700 of FIG. 7B) faces and a direction in which the front plate (e.g., a front plate 730 of FIG. 7B) faces by enabling an image source (e.g., image current) of a vertical polarization source to be generated through a disposition structure of the conductive dummy plates 610 and 620, radiation performance degradation of the antenna structure 500 may be reduced.

FIG. 6 is a diagram illustrating a radiation pattern of an antenna structure according to presence or absence of a conductive dummy plate according to an embodiment of the disclosure.

Referring to FIG. 6, in the antenna structure 500 operating in a 28 GHz band of FIG. 5A, in a case (pattern 603) in which the conductive dummy plates 610 and 620 are applied, it can be seen that a radiation performance of horizontal polarization (H-polarization) is similar to that of a case (pattern 604) in which the conductive dummy plates 610 and 620 are not applied, whereas in a case (pattern 601) in which the conductive dummy plates 610 and 620 are applied, it can be seen that a radiation performance of vertical polarization (V-polarization) is improved further than that of a case (pattern 602) in which the conductive dummy plates 610 and 620 are not applied. For example, in vertical polarization, when the conductive dummy plates 610 and 620 are applied, it can be seen that in a radiation performance of the antenna structure 500, there has been improved a null point existing in an elevation 90 degree area (area 605) of a case in which the conductive dummy plates 610 and 620 are not applied and that a radiation performance has been improved by extending a beam width in an upper area (area 606) and a lower area (area 607) of the electronic device.

Numerically, referring to Table 1, the antenna structure 500 operating in a low frequency band (n261 band) exhibits a gain of 6.5 dB before applying the conductive dummy plates 610 and 620 in a 50% section of a cumulative distribution function (CDF), but after the conductive dummy plates 610 and 620 are applied, the antenna structure 500 exhibits a gain of 6.9 dB; thus, it can be seen that a gain of 0.4 dB is substantially improved. Further, the antenna structure 500 operating in a high frequency band (n260 band) exhibits a gain of 7.0 dB before applying the conductive dummy plates 610 and 620 in a 50% section of the CDF, but after the conductive dummy plates 610 and 620 are applied, the antenna structure 500 exhibits a gain of 7.1 dB; thus, it can be seen that a gain of 0.1 dB is substantially improved.
