Internal diversity antenna

摘要

A diversity antenna provided inside a mobile communication terminal. In an internal antenna, a common ground element formed as a conductor having predetermined length grounds an antenna. A first radiating element radiates radiating a vertically polarized wave of a predetermined band. One end of the first radiating element is vertically connected to one end of the common ground element and the other end of the first radiating element is open. A second radiating element radiates radiating a horizontally polarized wave of the predetermined band. One end of the second radiating element is vertically connected to the other end of the common ground element and the other end of the second radiating element is open. A first and a second feeding element feeds electric current to the radiating elements.
