Abstract :
Two Dielectric Resonator Antenna (DRA) structures, Dielectric Image Line-slot and Microstrip-slot fed, are numerically investigated using two commercial software, HFSS and CST. Radiation characteristics of both antennas including return loss, radiation patterns and gain variation versus frequency are presented and compared for two DRAs. The effects of ground plane loss and dielectric loss on the radiation performance of the antennas are investigated. The results show that DIL-slot fed DRA has lower loss compare to microstrip-slot coupled DRA at 9.9 GHz.
