Abstract

A portable wireless terminal having a built-in antenna module is provided. In the portable wireless terminal: a body including an upper case frame, a lower case frame, and a main board installed between the upper case frame and the lower case frame; a built-in antenna module arranged on the main board; a conductor near the built-in antenna module , formed on or installed on at least one of the upper shell frame and the lower shell frame, so as to prevent the radiation performance of the built-in antenna module from being reduced due to external interference and improve the antenna performance.

Description

[0001] This application claims priority to Application No. 2004-96694, entitled "Portable Wireless Terminal with Conductor for Improving Antenna Properties," filed with the Korean Intellectual Property Office on November 24, 2004, and filed on March 2005 Priority of Application No. 2005-21747 entitled "Portable Wireless Terminal Having Conductor for Improving Antenna Properties" filed with the Korean Intellectual Property Office on the 16th, the contents of which are hereby incorporated by reference. technical field [0002] The present invention generally relates to a portable wireless terminal having a built-in antenna, and more particularly, to a portable wireless terminal having a conductor in a housing frame in the vicinity of the built-in antenna so that an appropriate combination between the conductor and the antenna device The degradation of the antenna radiation performance due to the user's finger touch is prevented, and the bandwidth is incre...
