Abstract
A triple-band hybrid (a combination of slot and CDRA) cylindrical Dielectric Resonator Antenna is presented in this article. By using the modified circular aperture, the CDRA gets excited with different segments notched out of the copper surface. The use of circular aperture radiator gives rise to triple hybrid modes generation in CDRA, i.e., (one due to the slot at the ground plane, HE11δ and HE21δ due to CDRA) and has the broadside radiation characteristic. The proposed antenna design works well in the mentioned frequency bands, i.e., 2.01–2.29 GHz; 3.39–3.87 GHz; 4.62–4.87 GHz with the fractional bandwidth (FBW) of 13.08%; 13.04%; 5.25%, respectively. The proposed archetype has an appreciable gain of 1.57 and 3.14 dBi at 2.14 and 3.68 GHz and the efficiency of the radiator is close to 90% at the above-mentioned resonating frequencies. The suggested prototype works well for the wireless application. Ansoft HFSS 16 simulation software has been used for modeling and investigating the prototype.
