Abstract

An antenna (100) comprising a substrate (140) and a folded radiating element (120). The folded radiating element (120) and the substrate (140) define a resonant cavity (220) which produces a wide beamwidth, and substantially hemispherical radiation pattern. An antenna constructed in accordance with the present invention can be incorporated into a transceiver system. The radiation pattern produced by the antenna is suitable for use in wireless communication systems operating in the PCS and DCS frequency ranges.
