Description
CROSS-REFERENCE TO RELATED APPLICATION(S)

This application is based on and claims priority under 35 U.S.C. § 119 to Korean Patent Application No. 10-2018-0166614, filed on Dec. 20, 2018, in the Korean Intellectual Property Office, the disclosure of which is incorporated by reference herein in its entirety.


BACKGROUND
1. Field

The present disclosure relates generally to an electronic device with an antenna.


2. Description of Related Art

A traditional electronic device is configured to have an antenna separated from a communication main body, or to have an antenna protruding to the outside of a housing. For example, the antenna may be an external antenna of the electronic device.


In recent years, embedded antenna methods have been introduced, and an antenna can be disposed inside a housing of an electronic device. In such an electronic device, the embedded antenna may be disposed as far as possible away from the center of the electronic device, in the inner space of the housing, with a circuit and a physical instrument (for example, a carrier, a holder, or a bracket).


However, propagation of communication radio signals may be interrupted by the housing of the electronic device, and there is a limit to a space of the housing in which a 5G radiation antenna module is mounted. Therefore, an array mounting size of a millimeter (mmWave) module is limited (for example, 1×4, 2×2), and thus effective isotropically radiated power (EIRP) may be increased.


An mmWave radiation coverage of the electronic device may be determined depending on the overall influence of the shape or structure of the housing, a mounting structure of the mmWave module, and an internal ground or a peripheral metal structure. In this case, a radiation pattern within the coverage region may indicate that a beamform radiated from the mmWave module in a free state is not uniform.


In particular, when a plurality of mmWave modules are mounted in the electronic device, ambient radiation environments of the plurality of mmWave modules are different. Therefore, beam distortion may appear differently. For example, since one antenna module may be positioned in the proximity of peripheral metal structures, and another antenna module may be positioned at a long distance from the peripheral metal structures, the respective antenna modules may have different ambient environments.


Thus, it may be advantageous to provide an electronic device which can adjust antenna beamforming radiated from an antenna module.


SUMMARY

The present disclosure has been made to address the above-mentioned problems and disadvantages, and to provide at least the advantages described below.


In accordance with an aspect of the present disclosure, an electronic device is provided that includes a housing including a first plate facing in a first direction, a second plate facing in a second direction opposite to the first direction, and a side surface member surrounding at least part of a space between the first and second plates; a printed circuit board including a first surface facing in the first direction and a second surface facing in the second direction, the printed circuit board being disposed in the housing; an antenna module disposed on the first surface of the printed circuit board and adjacent to the side surface member, forming a first gap therewith, the antenna module being configured to radiate an antenna beam in a third direction which is perpendicular to the first and second directions; a wireless communication circuit electrically connected with the antenna module, and configured to transmit or receive a signal having a frequency between 3 gigahertz (GHz) and 100 GHz; and a dielectric structure including a seating portion to have the antenna module mounted thereon, and configured to form the antenna beam to be radiated toward an outside of the housing in the third direction.

The printed circuit board 120 may be disposed between the first and second plates 111 and 112 and may include a first surface 120a facing in the first direction ({circle around (1)}) and a second surface 120b facing in the second direction ({circle around (2)}). The printed circuit board 120 may have a plurality of electronic components disposed therein, and may have a plurality of transmission circuits formed therein.


The electronic device 10 may have the antenna module 130 and the dielectric structure 140 disposed in the first direction ({circle around (1)}) with reference to the printed circuit board 120, and may have the first peripheral metal structure 153 and/or the second peripheral metal structure 160 disposed in the second direction ({circle around (2)}).


The first peripheral metal structure 153 may be a metallic body to connect a seated SIM card to the printed circuit board 120. The second peripheral metal structure 160 may be disposed between and in parallel with the first peripheral metal structure 153 and the second plate 112. The first peripheral metal structure 153 may include a SIM card socket, and the second peripheral metal structure 160 may include an internal support structure (for example, a support member) having at least a portion formed with a metallic material and supporting the printed circuit board 120. Hereinafter, the first peripheral metal structure 153 is referred to as a SIM card socket, and the second peripheral metal structure 160 is referred to as an internal support structure.


A SIM card socket device 150 may include a SIM card cover 151, a SIM card tray 152, and the SIM card socket 153. The SIM card cover 151 may be disposed in an opening formed on the side surface member 113 to face in the third direction ({circle around (3)}). The SIM card tray 152 may be connected to the SIM card cover 151, and may have a SIM card seated therein and may be inserted into and drawn out (i.e., removed from) in the third direction ({circle around (3)}). The SIM card socket 153 may electrically connect the seated SIM card to the printed circuit board 120. At least a portion of the SIM card socket 153 may include a metallic material.


The internal support structure is a support member which supports the printed circuit board 120, and may be disposed between the SIM card socket 153 and the second plate 112. The internal support structure may have at least a portion formed with a metallic material.


The internal support structure may have an internal cover 162 connected thereto. The internal cover 162 may be disposed between and in parallel with the second plate 112 and the SIM card socket 153. The printed circuit board 120, the SIM card socket device 150, the internal support structure, and the second plate 112 may be vertically stacked on top of one another.


The antenna module 130 may be disposed on the first surface 120a of the printed circuit board 120. For example, the antenna module 130 may include at least one antenna array 170 supporting communication of an mmWave frequency band. The antenna module 130 may be disposed on the first surface 120a of the printed circuit board 120 by the dielectric structure 140. The antenna module 130 may be disposed adjacent to the side surface member 113, and may be disposed to have a first gap g1 with an inner surface of the side surface member 113. The antenna module 130 disposed in the above-described structure may be disposed to radiate an antenna beam in the third direction facing in the direction perpendicular to the first and second directions ({circle around (1)}, {circle around (2)}). The third direction ({circle around (3)}) may be a direction that faces toward the outside of the housing 110 from the antenna module 130 through the side surface member 113.


The dielectric structure 140 may be disposed in front of the antenna module 130, such that an antenna beam radiated from the antenna module 130 can have a radiation pattern enhanced by the dielectric structure 140. The dielectric structure 140 adjacent to the front surface of the antenna array 170 may have a third gap g3 with the antenna module 130 to reduce a change in the resonant frequency of the antenna array 170 caused by the dielectric structure 140.


The antenna module 130 may be electrically connected with a wireless communication circuit (module). For example, the antenna module 130 may be configured to transmit and/or receive a signal having a frequency between 3 GHz and 100 GHz.


The dielectric structure 140 may have a seating portion to have the antenna module 130 seated thereon, and may be disposed between the side surface member 113 and the antenna module 130 to form an antenna beam radiated from the antenna module 130. The dielectric structure 140 may be disposed adjacent to the side surface member 113, and may have a second gap g2 with an inner surface of the side surface member 113. At least part of the surface of the dielectric structure 140 may be disposed to face the inner surface of the side surface member 113. The second gap g2 may be smaller than the first gap g1.


The dielectric structure 140 may include a support member of an injection molding material. Hereinafter, the dielectric structure 140 is referred to as a support member of an injection molding material.



FIG. 2 is a perspective view illustrating a state in which an antenna module is mounted in a dielectric structure, according to an embodiment. FIG. 3 is a perspective view illustrating another dielectric structure, according to an embodiment.


Referring to FIGS. 2 and 3, the support member 140 is fixed onto a printed circuit board 120 by a locking structure. The support member 140 includes a base 141 and a vertical sidewall 142. The base 141 is a bottom portion of the support member 140, and may be disposed in contact with a portion of a first surface of the printed circuit board (for example, the first surface 120a shown in FIG. 1). The vertical sidewall 142 extends along a circumference of the base 141, while protruding in a vertically upward direction.


The vertical sidewall 142 may be disposed on a front surface of an antenna array 170 to enhance a radiation pattern. The vertical sidewall 142 adjacent to the front surface of the antenna array 170 may have a third gap g3 formed with the antenna module 130 to reduce a change in the resonant frequency of the antenna array 170 caused by the vertical sidewall 142.


An inner space of the support member 140 surrounded by the vertical sidewall 142 may be a seating portion to which the antenna module 130 is fixed. The antenna module 130 may be fixed in parallel with the support member 140.


The vertically upward direction may be the first direction ({circle around (1)}). The base 141 may include at least one first opening 143, and the vertical sidewall 142 may include at least one second opening 144. The second opening 144 may be a hole through which a portion of a soft circuit board, which electrically connects the antenna module to the printed circuit board 120, passes through.


The support member 140 may further include a protrusion 160 formed thereon to prevent the seated antenna module 130 from being released. The protrusion 160 may protrude from one vertical sidewall 142 in a fourth direction ({circle around (4)}). The fourth direction ({circle around (4)}) may be perpendicular to the first ({circle around (1)}), second ({circle around (2)}), and third directions ({circle around (3)}).


The vertical sidewall 142 may be disposed on the front surface of the antenna array 170 to enhance a radiation pattern. The vertical sidewall 142 adjacent to the front surface of the antenna array 170 may have the third gap g3 formed with the antenna module 130 to reduce a change in the resonant frequency of the antenna array 170 caused by the vertical sidewall 142.



FIG. 4 is a view illustrating a graph indicating a radiation distribution of an antenna module, according to an embodiment.


Referring to FIG. 4, a radiation pattern colored gray indicates a radiation pattern when there is no vertical sidewall on the front surface of the antenna array 170. It can be seen that unnecessary radiation on a lower side or rear surface is greater than radiation on a side surface which is a main radiation direction. Such a radiation pattern may be distorted by a dielectric included in the housing 110 and the internal cover 162 because a propagation speed of a signal changes according to each direction due to the dielectric included in the housing 110 and the internal cover 162. A radiation pattern colored black indicates a radiation pattern after distortion of the radiation pattern caused by the dielectric included in the housing 110, and the internal cover 162 is compensated for by the vertical sidewall 142 disposed on the front surface of the antenna array as shown in FIG. 3. It can be seen that a gain is enhanced to 0.5 decibels (dB) to 2.9 dB in the main radiation direction. Symmetric beamforming is guaranteed and a front to back (FB) ratio is enhanced.



FIG. 5 is a cross-sectional view illustrating an antenna module mounting structure of an electronic device, according to an embodiment.


Referring to FIG. 5, regarding the electronic device 20, the same elements as in the electronic device 10 will not be described and only different elements will be described. The electronic device 20 may differ from the electronic device 10 in a dielectric structure 240.


The electronic device 20 includes the dielectric structure 240 formed in front of the antenna module 130 disposed on the printed circuit board 120. The dielectric structure 240 may be formed on a portion facing the front portion of the antenna module 130 as an injection molding structure. The dielectric structure 240 may be formed on a corner region between the first plate 111 and the side surface member 113. The dielectric structure 240 may differ a surface facing the antenna module 130 as an inclined surface.


In the electronic device 20, nonmetallic portions may be substantially re-distributed, that is, some nonmetallic structures P1 positioned under the printed circuit board 120 may be deleted and the dielectric structure 240 which is a nonmetallic structure positioned in front of the antenna module over the printed circuit board 120 may be added, such that a gain of the antenna module 130 can be generated. A distribution of dielectrics in a main radiation direction of the antenna array 170 is uniform or similar, such that radiation pattern distortion caused by a housing 110 can be mitigated.



FIGS. 6A and 6B are views illustrating graphs indicating radiation distributions of an antenna module according to whether there is a dielectric structure, according to an embodiment. A pattern colored black indicates a phase of a signal and a pattern colored gray indicates a radiation pattern.


Referring to FIGS. 6A and 6B, when there is a dielectric structure (for example, the dielectric structure 240 shown in FIG. 5) in FIG. 6B, null of a side surface disappears from a radiation pattern due to the dielectric structure, a phase distribution of a main beam is changed in the radiation distribution, and a phase change in the direction of 90 degrees is mitigated, in comparison to FIG. 6A in which there is no dielectric structure.



FIG. 7 is a cross-sectional view illustrating an antenna module mounting structure of an electronic device, according to an embodiment.


Referring to FIG. 7, regarding the electronic device 30, the same elements as in the electronic device 10 will not be described and only different elements will be described. The electronic device 30 may differ from the electronic device 10 in a dielectric structure 340.


The electronic device 30 includes an antenna module 130 disposed on the printed circuit board 120 and formed in front of the dielectric structure 340. The dielectric structure 340 may be formed on a portion facing the front portion of the antenna module 130 as an injection molding structure. The dielectric structure 340 may be extended between the first plate 111 and a lower end of the side surface member 113. The dielectric structure 340 may define a surface facing the antenna module 130 as an inclined surface. The nonmetallic structure P1 may be present, and to compensate for this, the dielectric structure 340 may have a larger volume than the dielectric structure 240.



FIG. 8A is a view illustrating a graph indicating a radiation distribution of an antenna module according to a dielectric structure, according to an embodiment. FIG. 8B is a view illustrating a graph indicating a radiation distribution after the antenna module of FIG. 8A is rotated by 90 degrees, according to an embodiment. A pattern colored black is a radiation pattern before the dielectric structure 340 is added, and a pattern colored gray is a radiation pattern after the dielectric structure 340 is added.


Referring to FIGS. 8A and 8B, it can be seen that a coverage of an antenna radiation beam is maximized by adding the dielectric structure 340 to the antenna module 130. The antenna module can enhance a beam coverage sensitivity within +/−45 degrees on a side surface.



FIG. 9 is a view illustrating a graph indicating a resonant frequency of an antenna array 170, according to an embodiment.


Referring to FIG. 9, the antenna array may communicate at the frequency of 27.5 GHz. A graph 901 indicates a resonant frequency before an antenna module 130 is mounted on a dielectric structure 140. A resonance is formed with reference to about 28 GHz band. A graph 902 indicates a resonant frequency after the antenna module 130 is mounted on the dielectric structure 140. A resonance is formed with reference to about 27.5 GHz band and thus is suitable for use in the frequency of 27.5 GHz for communication. The resonance of the antenna array 170 may be detuned before the antenna module 130 is mounted on the dielectric structure 140, and performance can be enhanced when the antenna module 130 is mounted on the dielectric structure 140.
