Low Profile Circularly Polarized Elliptical Dielectric Resonator Antenna

Two circularly polarized conformal excited elliptical dielectric resonator antenna are presented. The first one has a dielectric constant of $\varepsilon_{r}= 20$ and the second one has dielectric constant of $\varepsilon_{r}= 25$. The two antennas provide S 11 bandwidths 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 bore-sight gain at the desired frequency range.
