Abstract

A polarization pattern diversity antenna is described that is easy to manufacture, has a compact planar shape and radiates a nearly omnidirectional radiation pattern in the horizontal plane. Two feed points, each one attached toa copper patch, are operated in phase and 180° out of phase to separately receive or transmit two different components of a signal. The copper patches are arranged symmetrically on one side of a dielectric layer in such a way as to reduce the r.f coupling between the two modes of operation and thus increase the radiation efficiency and isolate the overall input/output ports for the different signal components. The ground plane, situated on the underside of thedielectric layer, allows the antenna to operate like a resonant slot when the feed points are excited in phase. Using diversity, the antenna can reduce the multipath fading effects inherent in mobile communications
