Abstract

Switched pattern diversity reception is implemented by using antenna elements with different directional radiation patterns and switching the receiver to the element providing the best output. The use of pattern diversity can improve system performance. The performance of various ideal pattern diversity antennas is simulated. The results are compared with an ideal omnidirectional antenna and with energy density antennas. Significant improvements are shown for diversity antennas in multipath environments characterized by Rayleigh and Rician amplitude distributions
