Abstract
A composite antenna has a conductor ground plate having a preset shape, a plurality of antenna elements faced to each other and separated from the conductor ground plate by predetermined element interval, and feeding terminals for feeding power to the antenna elements via transmission lines in the same phase. The antenna elements and the feeding terminals are disposed symmetrically with respect to the center of the conductor ground plate. Even when the number of operating frequencies is increased to three or more, the composite antenna is thin and small and can provide a predetermined directional characteristic.
