<p><P>PROBLEM TO BE SOLVED: To provide a built-in antenna apparatus for a portable terminal, which is configured to achieve more excellent radiation efficiency than that of the conventional PEA (PCB Embedded Antenna). <P>SOLUTION: The built-in antenna apparatus for a portable terminal includes: a substrate including a ground region and a non-ground region; an antenna main radiation pattern formed in a pattern with a preset shape within the non-ground region of the substrate; at least one sub-radiation pattern formed in a pattern shape while having a preset spacing distance from the antenna main radiation pattern; and a conductive plate with a preset height, electrically connecting the sub-radiation pattern with the antenna main radiation pattern or with at least any one of the sub-radiation patterns. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
