Abstract
A diversity antenna for receiving radio frequency (RF) signals includes a horizontally-polarized antenna element coupled to a vertically-polarized antenna element in a fixed orthogonal relationship. The vertically-polarized antenna element is a blade antenna which includes a vertically-oriented printed circuit board (PCB) on which is disposed a pair of conductive strips. The horizontally-polarized antenna element includes two loop antennas which are arranged and conductively coupled in parallel. Each loop antenna includes a horizontally-oriented, disc-shaped PCB on which is disposed a pair of conductive loops. To facilitate the orthogonal coupling between the pair of antenna elements, each disc-shaped PCB includes a central slot dimensioned to receive the vertically-oriented PCB. In operation, the independent signal feeds produced by the first and second antenna elements can be processed to reduce any cross-polarization effects present in either signal feed, thereby providing the diversity antenna with full, omnidirectional signal coverage.
