ABSTRACT:
A portable wireless terminal with a main body having a main board, and a battery pack detachably mounted in the main body and used as power supply means for the terminal, wherein the battery pack includes an upper case frame; a lower case frame coupled with the upper case frame to provide a predetermined installation space therebetween; a battery cell having a conductive outer surface fixed on the installation space; and a radiator fixed to an inner surface of the upper case frame, and having a feed pin and a ground pin that are exposed on the lower case frame along a detour route around the battery cell. Since the radiator is not installed inside the main body but inside the battery pack, an antenna mounting space can be removed from the main body, which contributes to a slim profile and a lightweight feature of the wireless terminal.
