Abstract

An electronic device includes a housing including at least one conductive portion disposed along at least a portion of a side surface of the housing, the at least one conductive portion configured to receive or to transmit a signal, a first module inside the housing and adjacent to the at least one conductive portion, and a first printed circuit board inside the housing and comprising a communication line electrically connected to the first module, wherein the communication line extends along an edge of the first printed circuit board to have a resonance frequency different from a frequency of the signal received or transmitted by the at least one conductive portion.

First claim

What is claimed is:

1 . An electronic device comprising:
a housing comprising at least one conductive portion disposed along at least a portion of a side surface of the housing, the at least one conductive portion configured to receive or to transmit a signal; a first module inside the housing and adjacent to the at least one conductive portion; and a first printed circuit board inside the housing and comprising a communication line electrically connected to the first module, wherein the communication line extends along an edge of the first printed circuit board to have a resonance frequency different from a frequency of the signal received or transmitted by the at least one conductive portion.

2 . The electronic device of claim 1 ,
wherein the communication line comprises: a first communication line disposed along an edge of the first printed circuit board and connected to the first module; and a second communication line electrically connected to the first communication line.

3 . The electronic device of claim 1 , wherein the communication line comprises a first communication line and a second communication line connected to a stub in parallel.

4 . The electronic device of claim 3 , wherein the first communication line and the second communication line extend in a loop shape from the stub.

5 . The electronic device of claim 1 , further comprising:
a second printed circuit board electrically connected to the first printed circuit board; and at least one processor disposed on the second printed circuit board and electrically connected to the communication line.

6 . The electronic device of claim 4 , wherein a first end of the second communication line is connected to the first communication line through the stub, and
wherein a second end of the second communication line, different from the first end, is connected to a switch.

7 . The electronic device of claim 6 , wherein the second communication line is configured to be switchable, via the switch, to a first state in which the second end is open or to a second state in which the second end is electrically connected to a ground.

8 . The electronic device of claim 3 , wherein the first communication line is a low-speed communication line.

9 . The electronic device of claim 1 , wherein the resonance frequency of the communication line is 700 MHz or less, or 1.0 GHz or more and 1.8 GHz or less.

10 . The electronic device of claim 1 , wherein the first module is a camera adjacent to the at least one conductive portion.

11 . The electronic device of claim 1 , wherein the first module is a sensor adjacent to the at least one conductive portion.

12 . The electronic device of claim 1 , wherein the at least one conductive portion is configured to operate as an antenna radiator.

13 . The electronic device of claim 3 , wherein as the first communication line having a first length and the second communication line having a second length are connected in parallel, a total length of the communication line is a sum of the first length and the second length.

14 . The electronic device of claim 1 , wherein the communication line extends in a loop shape along the edge of the first printed circuit board.

15 . The electronic device of claim 8 , wherein the first communication line is a I2C (inter integrated circuit) communication line.

16 . The electronic device of claim 3 , wherein the stub is an open stub or a short stub.

17 . The electronic device of claim 4 , wherein the first communication line and the second communication line extend from the stub along the edge of the first printed circuit board.

18 . The electronic device of claim 3 , wherein the first communication line is connected to the first module through the stub.

19 . The electronic device of claim 4 , wherein a first end of the second communication line is connected to the first communication line through the stub, and
wherein a second end of the second communication line, different from the first end, is connected to a ground.

20 . The electronic device of claim 4 , wherein a first end of the second communication line is connected to the first communication line through the stub, and
wherein a second end of the second communication line, different from the first end, is open.
