Abstract

Disclosed is an electronic device including a display; a rear plate including a conductive material; a side member including a conductive material and disposed to surround a space between the display and the rear plate; a printed circuit board disposed between the display and the rear plate; an antenna pattern at least partially disposed between the printed circuit board and the rear plate and at a position corresponding to a slit between the rear plate and the side member; and a communication module which generates a communication signal transmitted to a power feeding unit. A portion of the antenna pattern may be electrically connected to the power feeding unit. Another portion of the antenna pattern may be electrically connected to a ground region of the printed circuit board. The power feeding unit may be connected to a portion of the side member. Various other embodiments are possible.

First claim

What is claimed is:

1 . An electronic device comprising:
a display; a rear plate including a conductive material; a side member including a conductive portion and disposed to surround a space between the display and the rear plate, the conductive portion of the side member includes a first portion, a second portion, and a third portion; a printed circuit board disposed between the display and the rear plate and including a ground region; an antenna pattern at least partially disposed between the printed circuit board and the rear plate and disposed at a location corresponding to a first slit formed as the rear plate and the conductive portion of the side member are at least partially spaced apart from each other, wherein the antenna pattern is electrically connected with the ground region; a feeding part electrically connected with the antenna pattern and the conductive portion of the side member; and a communication module configured to feed the antenna pattern and the side member through the feeding part and to transmit and/or receive wireless signals, wherein the first portion is located between the second portion and the third portion, wherein the first portion and the second portion are at least partially spaced apart from each other, with a second slit interposed therebetween, wherein the first portion and the third portion are at least partially spaced apart from each other, with a third slit interposed therebetween, wherein the feeding part is electrically connected with the first portion, wherein the first portion is electrically connected with the feeding part through a first connection member at a first point and is electrically connected with a ground part connected with the ground region through a second connection member at a second point different from the first point, and wherein the antenna pattern is electrically connected with the feeding part through a third connection member at a third point and is electrically connected with the ground part through a fourth connection member at a fourth point different from the third point.

2 . The electronic device of claim 1 , wherein, when viewed from above the rear plate, the antenna pattern at least partially overlaps the first slit.

3 . The electronic device of claim 1 , wherein the first portion is extended in a first direction, and
wherein at least a portion of the first slit is extended in the first direction.

4 . The electronic device of claim 1 , wherein the first connection member, the second connection member, the third connection member, or the fourth connection member includes a C-clip.

5 . The electronic device of claim 1 , further comprising:
a flexible printed circuit board, wherein the antenna pattern is formed in the flexible printed circuit board.

6 . The electronic device of claim 1 , wherein the communication module is configured to feed the antenna pattern and the side member and to transmit and/or receive the wireless signals corresponding to a first frequency band and a second frequency band different from the first frequency band.

7 . The electronic device of claim 6 , wherein the first frequency band is lower than the second frequency band,
wherein the conductive portion of the side member is configured to implement a first resonant frequency corresponding to the first frequency band, and wherein the antenna pattern is configured to implement a second resonant frequency corresponding to the second frequency band.

8 . The electronic device of claim 1 , wherein the display includes a black matrix (BM) region in which content is not displayed, and
wherein, when viewed from above the rear plate, the antenna pattern at least partially overlaps the BM region.

9 . The electronic device of claim 1 , wherein the printed circuit board includes a first region including the ground region and a second region in which the ground region is absent, and
wherein, when viewed from above the rear plate, the antenna pattern at least partially overlaps the second region.

10 . The electronic device of claim 9 , wherein the first region of the printed circuit board at least partially overlaps the rear plate, and
wherein the second region of the printed circuit board at least partially overlaps the first slit.

11 . The electronic device of claim 1 , wherein the ground region is electrically connected with the rear plate.

12 . The electronic device of claim 1 , wherein a length of the antenna pattern in one direction is configured to be smaller than or equal to a thickness of the first slit.

13 . The electronic device of claim 1 , wherein the side member is divided into a plurality of portions, and
wherein a length of the antenna pattern in a direction parallel to the first slit is configured to be smaller than a length of at least one of the plurality of portions.
