Compact Triple Band Circularly Polarized Dielectric Resonator Antenna for Positioning and Navigational Application

This article presents a compact dielectric resonator antenna for GPS and RNSS applications. Triple band circular polarization characteristic is obtained through a corner truncated modified rectangular DR along with three conformal strips. The parametric and simulated analysis is investigated by Ansys HFSS. The proposed antenna covers an L5 band of 1.164-1.188 GHz, an L1 band of 1.565-1.607 GHz, and an RNSS band of 2.484-2.50 GHz having RHCP in the lower two band whereas LHCP in the upper band. The gain of 4 dBic, 5.9 dBic, and 4 dBic across the first, second, and third operating frequency bands respectively.
