Heat dissipation sheet-integrated antenna module

Abstract

Provided is a heat dissipation sheet-integrated antenna module which maintains a heat dissipation performance and an antenna performance to be equal to or better than those of a structure where a heat dissipation sheet and an antenna module are separated. The presented heat dissipation sheet-integrated antenna module is configured by coupling a heat dissipation sheet having a slit formed therein to an upper or lower part of an antenna pattern. Therefore, the antenna pattern of the antenna module is operated as an auxiliary heat dissipation member or the heat dissipation sheet is operated as an auxiliary radiator of the antenna module.

Description

technical field [0001] The present invention generally relates to an antenna module, and in particular, the present invention relates to a heat sink integrated antenna module integrally provided with a heat sink for dissipating heat generated in a portable device. [0002] This application claims priority from Korean Patent Application (Application No. 10-2015-0010067) filed on Jan. 21, 2015, the entire contents of which are hereby incorporated by reference in this application for all purposes. Background technique [0003] Due to the development of technology, high performance, size reduction, and weight reduction of electronic devices are becoming important issues. [0004] As electronic devices become more complex, compact, and lightweight, the internal space of the electronic devices decreases, and thus heat generated in the devices cannot be effectively dissipated. If the electronic device cannot effectively dissipate the heat generated therein, it may cause problems s...

AI Technical Summary

Problems solved by technology

[0009] However, since the heat sink is made of a metal material for effective heat dissipation, there is a problem that when the heat sink is attached to the antenna module installed in the portable terminal, the radiation performance of the antenna module deteriorates.

In this case, when the heat sink is applied to the rear cover (rear (battery) case) for heat dissipation of the portable terminal, the heat sink degrades the communication performance of the antenna module, so the heat sink is applied to the outside the area of

Therefore, the area of ​​the heat sink is reduced, thereby deteriorating the heat radiation effect

[0011] In addition, when the heat sink is installed in the portable terminal separately from the antenna module, space utilization is reduced, and thus it is difficult to downsize the portable terminal
