Abstract

An electronic device is provided. The electronic device includes a housing, an antenna radiating body including a conductive metal, a first member disposed within the housing and electrically connected to the antenna radiating body, a printed circuit board (PCB) disposed within the housing, a flexible connecting member disposed between at least a portion of the first member and at least a portion of a second member and including a conductive material, and a capacitor including a first conductive plate that contacts the second member or formed by a portion of the second member, a second conductive plate, separated from the first conductive plate and electrically connected to the PCB, and a dielectric layer inserted between the first conductive plate and the second conductive plate.

First claim

What is claimed is:

1. An electronic device, comprising:
a housing comprising a metal material portion;
a first conductive member that contacts at least a portion of the metal material portion, or that is formed by the metal material portion;
a second conductive member separated from the first conductive member, wherein at least a portion of the second conductive member is electrically connected to a ground; and
a capacitor disposed between the first conductive member and the second conductive member,
wherein the capacitor is configured to conduct a current from the metal material portion of the housing to the ground.

2. The electronic device of claim 1 ,
wherein the first conductive member is a flexible printed circuit board (FPCB), and
wherein the second conductive member is a stiffener.

3. The electronic device of claim 1 ,
wherein the first conductive member is a key flexible printed circuit board (FPCB), and
wherein the second conductive member is a metallic member.

4. The electronic device of claim 3 , wherein the capacitor is formed to be implemented as a separate capacitor for each key.

5. The electronic device of claim 4 , wherein the key FPCB is formed for at least one of a volume key, a power key, or a home key.

6. The electronic device of claim 1 , wherein the capacitor comprises a bonding member to connect to the second conductive member.

7. The electronic device of claim 1 , wherein the second conductive member contacts the capacitor or is formed as a portion of the capacitor.
