A Novel Compact Differential-Fed Dual-Polarized Dielectric Resonator Antenna

In this communication, a novel compact two dualpolarized (DP) differential-fed high input-isolation dielectric resonator antenna (DRA) is explored. The DRA is consisted of a rectangular dielectric resonator (DR) excited by a rectangular slot on the ground plane. Whilst, on the front plane, two curved differential microstrip feds were etched to excite TE^X₁₁₁ and TE^y₁₁₁ radiating modes. For the purpose of validating the suggested design, an archetype of the proposed radiator is modeled and simulated. The proposed antenna achieves the DP performance of left hand circularly polarized (LHCP) and right hand circularly polarized (RHCP) waves simultaneously within the operating band range 5.7-6 GHz. The ports isolation is above -32.65 dB. The antenna real-state measures 20×20 mm².The characteristics of the proposed antenna make it appropriate for applications utilizes IEEE 802.11ac band.
