ABSTRACT:
An antenna element includes a conductive ground plane, planar first and second antenna elements, and feeding points. The first antenna element confronts the ground plane at a given interval, and the second antenna element surrounds parts of the outer periphery of the first antenna element at a certain interval. Each one of the feeding points is provided to the first and the second antenna elements for feeding high-frequency signals to those elements. The foregoing construction allows achieving a compact antenna device that can perform a polarization diversity communication.
