Electronic device with antenna device

Abstract

An electronic device with an antenna device is provided. The electronic device includes a case member that includes a first face, a second face disposed opposite to the first face, and side walls that enclose a space between the first face and the second face, a first metallic member that forms at least a portion of the side walls of the case member or is formed adjacent to the side walls, a metal pattern disposed within the case member and extends from a portion of the first metallic member to another portion of the first metallic member, the first metallic member and the metal pattern electrically forming at least a portion of a closed loop, a wireless communication circuit electrically connected to a portion of the metal pattern, a grounding member positioned within the case member, and a portion of the metal pattern disposed adjacent to the grounding member.

Description

technical field [0001] The present disclosure relates generally to electronic devices, and more particularly, to electronic devices capable of transmitting / receiving radio frequency (RF) signals. Background technique [0002] In general, an electronic device refers to an electronic device according to a stored program (for example, an electronic scheduler, a portable multimedia reproducer, a mobile communication terminal, a tablet PC, an image / sound device, a desktop / laptop PC, a car navigation system, or a home appliance. ) A device that performs a specific function. For example, such electronic devices may output information stored therein as sound or images. As the degree of integration of such electronic devices has increased, and high-speed and large-capacity wireless communications have become popular, multiple functions have recently been equipped into a single electronic device such as a mobile communication terminal. For example, in addition to communication funct...

Problems solved by technology

[0004] However, in a miniaturized electronic device such as a mobile communication terminal, it may be difficult to secure a space for arranging the antenna device

Furthermore, although it is necessary to arrange a plurality of antenna devices (or radiation conductors) so that the electronic device operates in a plurality of different frequency bands, it may be difficult to secure a space for mounting such an antenna device in a miniaturized electronic device.

[0005] In addition, in an electronic device that uses a metal material as a case member in order to make the appearance pleasing and to secure impact resistance, etc., it may be difficult to secure the performance of the antenna device
