A new design of a compact dielectric resonator (DR) wideband antenna, catering the ultra-wideband (UWB) spectrum and beyond, along with dual-band circular polarization characteristics is presented in this literature. The antenna is realized by placing a pair of orthogonally placed DRs over a planar “I”-shaped monopole. Fundamental modes of TE10δ ( and and TE11δ ( and are excited at 3.8 and 6 GHz by incorporating a pair of orthogonally placed DRs that generate the lower and upper band of circular polarization, from 3.7 to 4.4 GHz (17.28%) covering downlink and from 5.8 to 6.2 GHz (11.56%) for uplink C-band communication satellites. The antenna provides an overall impedance bandwidth of 2.1 to 13 GHz (146.33%), thus covering UWB and lower end of the Ku-band. Novelty of this work lies in achieving UWB and dual-band circular polarization characteristics in a single antenna system.
