Metal Body Antenna Having Loop Type Radiation Elements

A metal body antenna having loop type radiation elements in which a housing unit is used as an antenna includes a radiation element supplied with a signal from a feeding power port, a ground coupled to the radiation element by loop coupling and in which an induction current is generated, and a frame bezel unit having an open end part separated from the ground by a dielectric and a gap. The frame bezel unit having the open end part supplied with an electric current induced into the ground is connected, and the metal body antenna operates in a wideband in multiple bands having an electrical length of a half wavelength. Accordingly, the bezel unit of a frame unit is effectively used and all of the Penta bands (i.e., GSM850, EGSM, DCS, PCS, and W2100) used in mobile phones is satisfied through a wideband multi-antenna structure having a small radiation loss. 本发明涉及将壳体部作为天线的具备环型辐射单元的金属体天线，具备半波长的电长度并在多频带以宽带运行，包括：辐射单元，从供电端口获得信号输入；接地部，与上述辐射单元环耦合并产生感应电流；框架边框部，具备通过电介体及缝隙与上述接地部分离形成的开放的终端部；框架边框部，具备获得在上述接地部感应的电流的开放的终端部。因此，
