Abstract :
A method of using different diameters of conducting plates to tune the resonant frequency of cylindrical or ring dielectric resonator (DR) antenna, is presented. This technique has the following two advantages for the DR antenna design. The first is that it provides a very easy way of tuning a DR antenna to operate at the design frequency without changing the antenna performance. Secondly, it can be used to reduce the DR antenna size, because the maximum frequency tuning range can reach about 300 to 500 MHz lower than the original design frequency.
