Very Thin Dielectric Resonator Antenna For Wireless Communications

In this paper, a very thin rectangular dielectric resonator antenna (Al2O3, er = 9.8) is presented. A strip connected to a probe is used as feed mechanism. Moreover, at the dielectric resonator antenna back and top faces we have placed parasite strips to excite new resonances. The proposed antenna exhibit compact dimensions (0.9 x 8 x 7 mm3), very wide band (50.89%), good performances and a maximum gain of about 10.86 dBi. The dielectric resonator antenna performances is simulated on Ansoft HFSS and CST microwave studio.
