Abstract :
A circular polarised and a switchable cylindrical dielectric resonator antenna are reported. The switchable antenna provides two linear polarised, one circular polarised, and a non-radiating mode. The experimental results of the resonant frequency, boresight axial ratio, gain, unloaded Q-factor, impedance bandwidth and radiation efficiency for both the antennas are presented and compared with the theoretical values
