dc.description.abstractIn this paper, a cylindrical dielectric resonator antenna (CDRA) offering low cross-polarization (XP) for point-to-point communication systems is presented. Three linear arrays of air vias (LAAV) are incorporated along the H-plane of a conventionalCDRAin order toweaken the undesired XP generating fields due to the orthogonally resonating HEM21X mode. A set of parametric studies are conducted on the design parameters of the 3-LAAV in CDRA to understand the sensitivity of boresight XPD on the 3-LAAV design parameters. Field distributions in CDRA before and after the incorporation of LAAV are extensively studied to draw a conclusive inference. The 3-LAAV loaded CDRA offers 39 dB higher boresight XP suppression in comparison to the conventional CDRA. The proposed technique is experimentally validated. The measured result shows an XP isolation of 56 dB at the boresight, 55 dB and 38 dB over ±15 % of half-power beamwidth (HPBW) in the E-plane and H-plane of radiation, respectively. This result is well above the minimum cross-polarization discrimination (XPD) requirements for the satellite earth station antennas.en
