FIG. 2D is a diagram schematically illustrating another arrangement of the plurality of patch plates of FIGS. 2A to 2C.

Referring to FIGS. 2A to 2C , an electronic device 220 (eg, the electronic device 101 of FIG. 1 ) according to an embodiment includes a

housing

222 , 228 , and 229 , at least one

support structure

221 , 224 and 226), a display 223, a battery 225, and an antenna 227.

The

housings

222 , 228 , and 229 may form the exterior of the electronic device 220 . The

housings

222, 228, and 229 include a front housing 222 (eg, a front cover glass) surrounding the front outer surface of the electronic device 220 and a side housing 229 ( For example, a bezel frame) and a rear housing 228 (eg, a rear cover glass) that surrounds a rear outer surface of the electronic device 220 .

On the other hand, Figure 2a shows that the housings (222, 228, 229) are divided into three parts covering the front, side and rear, respectively, but this is only one example, for example, the side housing 229 It may be integrally formed with the front housing 222 or the rear housing 229 . Alternatively, the entire exterior of the electronic device 220 may be formed by coupling the front housing 222 and the rear housing 228 to each other without a separate side housing 229 . Alternatively, it should be noted that the

housings

222, 228, and 229 may be formed as two housings divided in different directions and numbers, for example, upper and lower. Unless stated to the contrary, the front, side, and bottom surfaces refer only to portions where the housing is positioned relative to the electronic device 220, and detailed descriptions thereof will be omitted.

The rear housing 228 has a structure surrounding the rear outer surface of the electronic device 220 so that the radiating portion 227-1 of the antenna 227 is not directly exposed to the outside, and the radiating portion ( 227-1) can be reduced. For example, a portion of the rear housing 228 overlapping the radiation unit 227-1 in the front-back direction (eg, the z-axis direction) is formed of a non-conductive material, so that transmission from the radiation unit 227-1 The gain of radio waves can be reduced. According to various embodiments, overlapping parts may be understood as overlapping parts when viewed from one direction.

The

support structures

221 , 224 , and 226 are disposed inside the

housings

222 , 228 , and 229 and include at least one or more of the plurality of

electronic components

223 , 224 , and 225 accommodated inside the electronic device 220 . Electronic components can be supported.

The radiating part 227 - 1 and the ground part 227 - 5 of the antenna 227 may be respectively disposed on both sides of the

support structures

221 , 224 , and 226 . According to this structure, since the

support structures

221, 224, and 226 that already exist to perform functions required in the electronic device 220 can be used as a substrate for the antenna 227, mounting Space efficiency can be improved. In addition, typically, in order to secure the rigidity of the electronic device 220, the

support structures

221, 224, and 226 have a sufficient thickness, so that the thickness of the substrate of the antenna 227 is improved. By having the effect, the radiation efficiency of the antenna 227 can also be improved.

For example, the

support structures

221, 224, and 226 may include a first frame 221 (eg, a front frame) for supporting the display 223, a printed circuit board 224, and a second frame 226 ( eg rear frame). Meanwhile, the

support structures

221, 224, and 226 have been described as including two

frames

221 and 226, but any one of these frames may be omitted or an additional frame may be further provided. When a direction crossing the front and rear surfaces of the electronic device 220 is referred to as a "front-to-rear direction," the structure 221 positioned most forward among the one or

more support structures

221, 224, and 226 based on the front-back direction is referred to as a "front frame", and the support structure 226 located at the rearmost position may be referred to as a "rear frame". Meanwhile, if the

support structures

221 , 224 , and 226 include only one frame, the one frame may be referred to as a “rear frame” in that it is located at the rear with respect to the display 223 .

Hereinafter, a case in which the antenna 227 is installed in the rear frame 226 will be described as an example. On the other hand, unless otherwise stated, it should be understood that this document also includes an embodiment in which the antenna 227 is installed on the

support structures

221 and 224 other than the rear frame 226, and a detailed description thereof is omitted. I'm going to do it.

The display 223 may output visual information (eg, text, video, and/or image) and provide the information to the user through the front housing 222 .

The front frame 221 may support the display 223 toward the front housing 222 at the rear of the front housing 222 . For example, the rigidity of the front frame 221 may be higher than that of the

housings

222 , 228 , and 229 . According to this configuration, deformation of the entire electronic device 220 can be reduced by using the front frame 221 while relatively freely selecting the material of the

housings

222 , 228 , and 229 . For example, as shown in FIG. 2A , the front frame 221 may have a structure connected to the side housing 229 . For example, the front frame 221 and the side housing 229 may be integrally formed, but are not necessarily limited in this way, and the front frame 221 and the side housing 229 are separate members, respectively. Those skilled in the art will understand that it may be provided.

The front frame 221 may be formed of, for example, a metal material and/or a non-metal (eg, polymer) material. The front frame 221 may have a display 223 coupled to a front surface and a printed circuit board 224 coupled to a rear surface.

One or more components (eg, a processor, memory, and/or interface) may be mounted on the printed circuit board 224 . The processor may include, for example, one or more of a central processing unit, an application processor, a graphics processing unit, an image signal processor, a sensor hub processor, or a communication processor. On the printed circuit board 224, a board connector 224-1 for transmitting a signal to or receiving a signal from the antenna 227 and various electronic components 224-2 (eg, a camera module) can be fitted.

The battery 225 may supply power to one or more components (eg, the display 223 , the printed circuit board 224 , and/or the antenna 227 ). For example, at least a portion of the battery 225 may be disposed substantially on the same plane as the printed circuit board 224 . The battery 225 may be integrally disposed inside the electronic device 220 or may be disposed detachably from the electronic device 220 .

The rear frame 226 may be disposed behind the front frame 221 . For example, electronic components may be fixed to the rear frame 226 . For example, the rear frame 226 may be formed by injection molding. The rear frame 226 can also be referred to as "rear injection molding". For example, the rigidity of the rear frame 226 may be higher than that of the

housings

222 , 228 , and 229 . The rear frame 226, together with the front frame 221, may form a space in which at least one electronic component 224-1 can be disposed between the front frame 221 and the rear frame 226. . For example, a part of the front frame 221 and a part of the rear frame 226 may directly contact each other to form a space between the front frame 221 and the rear frame 226 . For example, the rigidity of the front frame 221 and the rear frame 226 is higher than that of the printed circuit board 224, respectively, and the printed circuit board 224 includes the front frame 221 and the rear frame ( 226) can be placed between them. According to such a rigid space, it is possible to reduce the transfer of impact from the outside to the relatively flexible printed circuit board 224, so that various electronic components 224-1 inside the electronic device 220 can reduce their damage. For example, since the rear frame 226 is formed of a dielectric material, at least a portion of the rear frame 226 may be used as a substrate for the antenna 227 . The rear frame 226 may include a seating portion 226-2, a connecting hole 226-1, a through portion 226-3, a recessed portion 226-4, and a protruding portion 226-5. .

The penetrating portion 226-3, the recessed portion 226-4, and the protruding portion 226-5 may be structures for appropriately supporting or accommodating various electronic components or various structures accommodated inside the electronic device 220. can For example, one or more electronic components 224 - 2 (eg, a camera module) installed on the printed circuit board 224 may pass through the through portion 226 - 3 and be exposed to the rear housing 228 . For example, the depression 226 - 4 may provide a space in which an electronic component (eg, an antenna) mounted on an inner wall of the rear housing 228 can be accommodated. For example, the protrusion 226-5 has a shape that is tightly fitted into a groove formed in the rear housing 228, so that the rear frame 226 and the rear housing 228 can be fastened to each other. there is. For example, the protrusions 226-5 and/or the depressions 226-4 may be formed not only on the rear face of the rear frame 226 as shown, but also on the front face. The protrusions 226-5 and/or the depressions 226-4 may be formed on the front face and/or other components adjacent to the rear face of the rear frame 226 (e.g., printed circuit board 224, battery 225 and And/or the rear housing 228 may support other components to reduce movement relative to the rear frame 226 . For example, the protrusions 226-5 may be formed not to interfere with other parts, but to function as reinforcing ribs for reinforcing the rigidity of the rear frame 226 itself. As such, the rear frame 226 does not have a simple planar shape, but may have protrusions 226-5, depressions 226-4, and/or penetrating portions 226-3 that perform various functions. make it clear that

On the other hand, unlike this, as one area of the rear frame 226, the seating portion 226-2 on which the antenna 227 is seated may have, for example, a substantially flat shape. For example, a region of the mounting portion 226-2 overlapped with the radiation portion 227-1 of the antenna 227 in the front-rear direction may be flat. According to this shape, as will be described later, since the thickness of the mounting portion 226-2 functioning as a dielectric is constant, it is possible to improve the ease of designing the pattern of the antenna 227.

The seating portion 226-2 is a portion located between the radiation portion 227-1 and the ground portion 227-5 of the antenna 227, and is made of a dielectric, a material that causes an electrical induction action. , can serve as a substrate for the antenna 227. For example, the seating portion 226-2 is formed of (i) polycarbonate or (ii) a synthetic material including polycarbonate and glass fiber (eg, PC+GF30%) It can be. Meanwhile, not only the seating portion 226-2, but also the rear frame 226 may be made of the same dielectric material. According to this configuration, since the rear frame 226 including the mounting portion 226-2 can be integrally injection-molded, the ease of manufacture can be improved.

For example, as shown in FIG. 2B , the seating portion 226 - 2 may have a more recessed shape than the adjacent peripheral area of the rear frame 226 , but is not necessarily limited thereto. For example, as shown in FIG. 2C, it should be noted that the seating portion 226-2' may not have a step with respect to an adjacent peripheral area of the rear frame 226'.

The connecting hole 226-1 is positioned adjacent to the seating portion 226-2 and may pass through the rear frame 226 in the front-rear direction. According to this configuration, the antenna 227 is physically and electrically connected to the printed circuit board 224 through the connecting hole 226-1, so that power can be supplied from the printed circuit board 224 to the antenna 227. can For example, the connecting hole 226-1 may be disposed within 1 cm from the seating portion 226-2. For example, a step (eg, a staircase) or an inclined surface may be disposed between the connecting hole 226-1 and the seating portion 226-2.

Meanwhile, although the connecting hole 226-1 is shown as being formed inside the rear frame 226, otherwise, the connecting hole 226-1 may have a shape recessed from the side of the rear frame 226. make it clear that For example, it should be noted that the rear frame 226 may further include a cutout communicating with the outside in the lateral direction of the connecting hole 226-1. According to this structure, the antenna 227 can be installed on the rear frame 226 using a manufacturing method as described later in FIG. 5B.

In some embodiments, at least some of the outer surfaces of the dielectric 227-3 of the antenna 227 may be disposed to face the inner wall of the connecting hole 226-1. For example, some of the exposed surfaces of the dielectric 227-3 that are not covered by the radiation portion 227-1 and the ground portion 227-5 are the inner walls of the connecting hole 226-1. It can be arranged to face. For example, the above-described exposed surface may face the inner wall of the connecting hole 226-1. For example, the dielectric 227-3 is formed on the inner surface of the connecting hole 226-1 so that there is no gap between the outer surface of the dielectric 227-3 and the inner surface of the connecting hole 226-1 facing each other. can be adhered to. Meanwhile, it should be noted that a fine gap may be generated between the outer surface of the dielectric 227-3 and the inner surface of the connecting hole 226-1 during the manufacturing process. For another example, the connecting hole 226 - 1 may be formed in a shape different from that shown in FIGS. 2A and 2B (eg, a triangle, a pentagon, a hexagon, a circle, and/or an ellipse). For example, at least some of the outer surfaces of the dielectric 227-3 of the antenna 227 may be disposed to face the inner wall of the connecting hole 226-1.

According to an embodiment, the dielectric 227-3 of the antenna 227 may include polyimide. For example, the dielectric 227-3 of the antenna 227 may include modified polyimide (MPI).

Antenna 227 may be disposed between, for example, rear housing 228 and battery 225 . The antenna 227 may include, for example, an ultra-wide band (UWB) antenna, a magnetic secure transmission (MST) antenna 297-1, a near field communication (NFC) antenna 297-3, and/or Alternatively, a wireless charging antenna 297-5 may be included. The antenna 227 may, for example, perform long-distance communication with an external device, short-distance communication, or wirelessly transmit/receive power required for charging. Hereinafter, the antenna 227 will be illustratively described as an ultra-wideband (UWB) antenna, but unless otherwise stated, the following description can be applied to other types of antennas. An ultra-wideband (UWB) antenna, for example, uses a high frequency (2.1 GHz to 10.6 Ghz) to achieve high positioning accuracy with an error range of less than 10 cm and a time of flight (TOF) method that can utilize a wide bandwidth of 500 Mhz. It may be a technology with enhanced security. Ultra-wideband (UWB) antennas may be used, for example, for access (ACCESS) technologies (e.g. security, car keys and/or digital keys), location based services (LBS) (e.g. indoor navigation), human/ It can be used for people/asset tracking technology, mobile payment, and internet of things (IoT) devices. As a positioning method using an ultra-wideband (UWB) antenna, for example, a time of flight (ToF) measurement method, a time of arrival (ToA) measurement method, and/or an angle of arrival (angle of arrival, AoA) measurement method, and the case where the antenna 227 uses the angle-of-arrival measurement method will be exemplarily described below, but it will be clarified that other measurement methods may be used unless otherwise stated.

The antenna 227 includes a radiating part 227-1 and a grounding part 227-5 disposed on both sides of the rear frame 226, respectively, and the above-described radiating part 227-1 and the grounding part 227-5. ) may include a dielectric 227-3 disposed between.

The radiation part 227-1 may be disposed on a rear surface of the seating part 226-2, and the ground part 227-5 may be disposed on a front surface of the seating part 226-2. For example, the antenna 227 is disposed on the rear frame 226, not on the

other support structures

221 and 224, and the radiating part 227-1 is disposed on the rear surface of the rear frame 226. can According to this configuration, the signal emitted from the radiation unit 227-1 is transmitted to internal parts (eg, the display 223, the board connector 224-1, and/or the electronic part 224-1) including various conductive materials. 2)), the radiation efficiency can be improved. In other words, as shown in FIG. 2A, a component having a conductive material, such as an electronic component 224-2, overlaps the antenna 227 in the front-back direction and is located on the opposite side of the radiating portion 227-1. It is possible to place Therefore, according to this configuration, the degree of freedom in the design of internal components of the electronic device 220 can be improved.

As shown in FIG. 2B, the first part 227-11 of the radiation part 227-1 covers the dielectric 227-3, and the second part 227-12 of the radiation part 227-1 ) may cover a part of the rear frame 226 (eg, the seating portion 226-2). Similarly, a first portion of the ground portion 227-5 covers the dielectric 227-3, and a second portion of the ground portion 227-5 covers the rear frame 226 (eg, the seating portion 226-3). 2)) can cover part of. According to this structure, since the dielectric disposed on the rear surface of the rear frame 226 is not required, it can be confirmed that the thickness of the entire antenna 227 can be drastically reduced by the thickness of the dielectric. For example, not only the bar-type electronic device 220 exemplarily shown in this document, but also the foldable-type electronic device 220, the rollable-type electronic device 220, and/or the slider-type electronic device 220. In this type of electronic device 220, the thickness can be dramatically reduced.

The radiation part 227 - 1 may include a plurality of patch plates P1 , P2 , and P3 in a patch shape. Using such a plurality of patch plates (P1, P2, P3), it is possible to detect the direction in which the electromagnetic source is located. For example, first, the magnitudes of signals received using the plurality of patch plates P1, P2, and P3 are compared, or second, the phases of signals received using the plurality of patch plates P1, P2, and P3. By comparing , it is possible to detect the direction in which the electromagnetic source is located. For example, according to the method of detecting the angle of arrival (AoA) through the phase difference of signals received using a plurality of patch plates P1, P2, and P3, as in the second method, the magnitude Compared to the comparison method, the direction of the electromagnetic source can be detected with high resolution.

The plurality of patch plates (P1, P2, P3) include, for example, three patch plates (P1, P2, P3) that are not located on a straight line, and the above-described three patch plates (P1, P2, According to P3), both components of horizontal polarization, which is a radio wave vibrating in a horizontal direction with respect to the traveling direction, and vertical polarization, which is a radio wave vibrating in a vertical direction with respect to the traveling direction, can be confirmed. Therefore, by detecting the above-mentioned angle of arrival (AoA), it can function as an ultra-wideband (UWB) antenna 227 that detects the direction of the electromagnetic source with high resolution.

For example, the three patch plates P1 , P2 , and P3 include (i) a first patch plate P1 disposed on the rear surface of the rear frame 226 and (ii) the rear frame 226 ) On the rear surface of the first patch plate (P1) in a first direction (eg, +x-axis direction) spaced apart from the patch-shaped second patch plate (P2), (iii) of the rear frame 226 On the rear surface, a patch-shaped third patch plate P3 spaced apart from the first patch plate P1 in a second direction (eg, the +y-axis direction) may be included. Here, the center of the first patch plate (P1), the center of the second patch plate (P2) and the center of the third patch plate (P3) are installed so as not to be located on a straight line, so that there are two types of horizontal polarization and vertical polarization All ingredients can be checked. For example, the first direction (eg, +x-axis direction) and the second direction (eg, +y-axis direction) may be orthogonal to each other on the rear surface of the rear frame 226 . For example, a first imaginary line connecting the center of the first patch plate P1 and the center of the second patch plate P2, and the center of the first patch plate P1 and the third patch plate P3 An angle formed by the second imaginary lines connecting centers to each other may range from about 45 degrees to about 135 degrees. For example, the angle formed by the first virtual line and the second virtual line may be about 90 degrees. In other words, each of the three patch plates P1 , P2 , and P3 may be disposed at a position corresponding to a vertex of a right triangle on the rear surface of the rear frame 226 . According to this structure, it is possible to improve the detection function as an ultra-wideband (UWB) antenna 227 . Meanwhile, the second patch plate P2 and the third patch plate P3 may have various shapes without being limited to the illustrated embodiment. For example, as shown in FIG. 2D , the second patch plate P2 and the third patch plate P3 are directed in an oblique direction with respect to the first patch plate P1 (eg, +/−x axis and +/−x axis). direction between the -y axis) to form a substantially triangular structure together with the first patch plate (P1). Meanwhile, unless otherwise stated, the antenna 227 may include two or fewer patch plates, or four or more patch plates.

As shown in FIGS. 2A and 2B , the dielectric 227-3 may be positioned at a portion overlapping the board connector 224-1 when viewed in the front-back direction. According to one embodiment, when viewed in the front-back direction, the dielectric 227-3 is (i) spaced apart from the second patch plate (P2) in a second direction (eg, +y-axis direction), (ii) It may be disposed at a position spaced apart from the third patch plate P3 in a first direction (eg, +x-axis direction). According to this shape, when viewed from the front-back direction, the three patch plates P1, P2, and P3 and the dielectric 227-3 can form a substantially rectangular shape as a whole. However, it is not limited thereto, and the three patch plates P1 , P2 , and P3 may form various shapes (eg, triangular structures) as described above.
