Problems solved by technology

[0005] However, since the capacitor is disposed adjacent to the C-clip, the prior art electronic device has an unfavorable space usage problem (i.e., space waste), especially securing space for the capacitor on the PCB.
Also, even if the related art electronic device has a capacitor in the upper part or surface of the PCB, the capacitance difference may be large according to the peripheral ground (GND), so there occurs a problem that radio frequency (RF) performance becomes unstable

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.

Description

technical field [0001] The present disclosure relates to a coupling structure of a capacitor in an electronic device having a capacitor. Background technique [0002] In order to provide various wireless communication functions, an electronic device may have at least one antenna. For example, an electronic device may have a mobile communication antenna, a digital broadcast receiving antenna, a Bluetooth antenna, a Global Positioning System (GPS) antenna, or a Near Field Communication (NFC) antenna. [0003] Electronic devices having such antennas have been developed in various forms, including electronic devices having metal housings. For example, such an electronic device may include a surrounding rim or cover formed by a metal housing. In this case, the metal casing also operates as an antenna. That is, as in an antenna, the metal case can transmit and receive wireless signals. [0004] Demand for such electronic devices having metal housings has grown. However, since...
