Abstract
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.
