In this communication, a compact cylindrical dielectric resonator antenna (CDRA) has been meticulously designed and thoroughly examined, showcasing diverse polarization characteristics across two distinct frequency ranges. This CDRA exhibits two noteworthy features: Firstly, it utilizes a pentagon-shaped aperture for excitation, effectively generating triple radiating modes within it, namely, HEM 11δ , HEM 12δ , and HEM 13δ . Secondly, the proposed CDRA offers support for two distinct polarization features, namely linear and circular polarization. The first band spans from 3.5 to 4.1 GHz, the second band extends from 6.57 to 7.1 GHz, and the third band covers the range of 7.79 to 8.7 GHz and the axial ratio in the proposed design falls below 3 dB in the second band, specifically from 6.9 to 7.1 GHz, as well as in the third band, which ranges from 8.35 to 8.7 GHz.
