Investigation of rectangular dielectric resonator antennas for switching polarisation diversity communication systems

In this paper a new application of a rectangular dielectric resonator antenna (RDRA) is presented. The experimental and simulation results of the RDRA show that the difference between the co- and cross-polar radiation is at least 15 dB. Using a single RDRA excited by two probes at two modes TE^x₁₁₁ and TE^y ₁₁₁, an antenna to receive two orthogonal polarisation waves is made. A communication system including a transmitter with two orthogonal dipoles and correspondence switching polarisation diversity receiver at 2.36 GHz was designed and implemented to demonstrate polarisation diversity using RDRA as the receiver antenna
