Simple Way of Controlling Cross-Polarized Radiations from Dielectric Resonator Antennas Without Affecting Other Salient Features

This work explores a simple technique of ground plane engineering to optimize the radiation characteristics of a Dielectric Resonator Antenna (DRA). It identifies the unruly fields in the corners of a ground plane, and subsequently discards the corners from a ground plane. This eventually leads to a uniform co-to-cross polar isolation over the entire azimuth. In addition, it helps in reducing the ground plane size by 20-25%, keeping all other antenna characteristics unchanged. This simple technique to XP reduction, especially over the Diagonal Plane should find potential applications in commercial usage.
