Reconfigurable aperture coupled rectangular dielectric resonator antenna

This paper presents the design of reconfigurable aperture coupled Rectangular Dielectric Resonator antenna (RDRA).The effect of varying the angular orientation of slot on the radiation characteristics and gain of the RDRA is investigated. It has been investigated that change in angular orientation of slot in aperture coupling feeding scheme can significantly affect the radiation properties and gain of RDRA. The measurement of radiation pattern on varying angular orientation of slot to 30 degree and 45 degree , left and right from original position of slot have been done. The optimun gain of 13.5 db is obtained in the designed antenna with the slot angular orientation of 45 degree left. The antenna is operated at the resonant frequency of 12 GHz.
