Low Profile Circularly Polarized Elliptical Dielectric Resonator Antenna

摘要

Two circularly polarized conformal excited elliptical dielectric resonator antenna are presented. The first one has a dielectric constant of εn_rn= 20 and the second one has dielectric constant of εn_rn= 25 .The two antennas provide Sn₁₁nbandwidths of 7.8% and 5.6% respectively. The axial ratio bandwidths of the antennas have been calculated as 1.9% and 1.5% respectively. Both antennas have provided useful boresight gain at the desired frequency range.
