Abstract :
In this paper, a square ring dielectric resonator (SRDR) antenna is presented which is excited by an U-shaped microstrip feed. The Q-factor can be lowered and bandwidth can be improved by removing the central portion of the dielectric resonator. The proposed feed for ring dielectric resonator antenna has been achieved -10 dB impedance bandwidth of 46.7% for 3.9 to 6.20 GHz. The proposed antenna gives the appreciable gain and better radiation pattern at the resonant frequencies.
