This article presents a technical review of circularly polarized (CP) dielectric resonator antennas (DRA) for wideband applications. The primary objective of this review is, to highlight the techniques used by different researchers for generating circular polarization in DRA. First, a general idea of circular polarization and it advantages over linear polarization is presented, and then all the major developments made in the CP DRA are highlighted. The emphasis of the paper is on the wideband circularly polarized dielectric resonator antenna. The current state of the art and all the realizable features of the CP DRA are addressed comprehensively. Finally, some recommendations for future CP DRAs are given and the paper ends with concluding remarks.
