In this article, design and analysis of a dual-band ring dielectric resonator based radiator with circular polarization features is explored. The presented ring DRA is excited with the help of a tilted modified square-shaped aperture. Two important attractive features of the present article are: (i) two radiating modes originated inside the ring DRA, i.e., HEM11δ and HEM12δ mode; (ii) tilted modified square aperture generates circular polarized (CP) wave in both the operating frequency bands. For verifying the simulated results, practical model of the proposed antenna has been fabricated and verified. Experimental outcomes display that the proposed radiator functions over dual frequency bands, i.e., 2.8–3.58 GHz and 5.5–5.92 GHz respectively. 3-dB axial ratio (AR) frequency ranges of the proposed radiator are 2.8–3.2 GHz and 5.85–6.0 GHz, respectively. These appearances make it appropriate for some important wireless applications such as wireless LAN (2.4/5.2 GHz) and WiMAX (2.5 GHz) applications.
