Abstract :
This paper presents a novel single feed Dielectric Resonator Antenna (DRA) exhibiting dual band operation in the Ku-band. The dual band operation is characterized by one circular polarized band centered at 13 GHz with 17.24% 3 dB axial ratio bandwidth and one band at 10.55 GHz with 5.58% 20 dB axial ratio bandwidth, which is basically approximating linear polarization. In both bands, the Dielectric Resonator is excited in its HEM11δ resonant mode. The design features a single feed design utilizing back-side microstrip excitation through novel bowtie cross slots.
