A rectangular dielectric resonator antenna (DRA) with a broadband circular polarization
(CP) radiation is presented using a single feed excitation. A simple feed method is proposed
using an open half-loop antenna that consists of three metallic strips. Utilizing such an
excitation has provided a circular polarization over a bandwidth of 7% that has been
increased further to 13% by adding a concentric parasitic open half-loop in the structure.
This has been achieved in conjunction with a 20% impedance matching bandwidth over the …

A rectangular dielectric resonator antenna (DRA) with a broadband circular polarization (CP) radiation is presented using a single feed excitation. A simple feed method is proposed using an open half-loop antenna that consists of three metallic strips. Utilizing such an excitation has provided a circular polarization over a bandwidth of 7% that has been increased further to 13% by adding a concentric parasitic open half-loop in the structure. This has been achieved in conjunction with a 20% impedance matching bandwidth over the same frequency range. The configuration has been rigorously modeled using a method of moments (MoM) model. The computed and measured results are in good agreement.
