This letter presents the design and study of a novel aperture coupled cylindrical dielectric resonator antenna (cDRA). Unique aspects of the proposed antenna design are that proposed aperture can excite six different hybrid radiating modes (HEM11δ, HEM11δ+1, HEM12δ-like, HEM12δ, HEM13δ, HEM14δ) in the cDRA; first time, quad-band quad-sense circular polarization is obtained in the dielectric resonator antenna structure; and radiation characteristics (broadsided) are almost same in all the frequency bands. These features make the proposed antenna structure relevant for L1/L2 GPS bands (1.2/1.5 GHz), CNSS, wireless LAN (2.4 GHz) as well as WiMAX (2.5 GHz) applications.
