Abstract

A rectangular dielectric resonator antenna (DRA) that is excited using an outer-fed square spiral strip has been studied theoretically and experimentally. Utilizing such excitation has provided a circular polarization over a broad bandwidth of ${sim 14}%$ in conjunction with an impedance-matching bandwidth of ${sim 11}%$. The structure has been rigorously modeled using a method of moments (MoM) model. A good agreement has been attained between computed and measured results.
