In this paper a new application of a Rectangular Dielectric Resonator Antenna (RDRA)is presented. The experimental and simulation results of an RDRA show that the difference between the co- and cross-polarization radiation levels is at least 15dB. Using a single RDRA exciting by two probes at two modes TEx 111 and TEy 111, an antenna to receive two orthogonal polarization waves is made. A communication system including a transmitter with two orthogonal dipoles and correspondence switching polarization diversity receiver at 2.36GHz was designed and implemented to demonstrate the application of polarization diversity of an RDRA as the receiver antenna.
