Abstract
Dielectric resonator antennas find widespread applications in high speed wireless systems because of low loss, compact size and light weight. In this study, performance of a multiband Dielectric Resonator Antenna (DRA) with higher gain and improved radiation efficiency for 3.8 GHz band Wi-Max, fixed point satellite links and 4.8GHz band 5G services and 5GHz wireless networks is presented. The proposed design consists of stacked rectangular dielectric resonator fed by a microstrip line placed above grounded Arlon substrate. Simulation results of the proposed DRA shows dualband operation from 3.65 to 4.45GHz and 4.7 to 5.6GHz with impedance bandwidth of 20.25 and 17.47% respectively. The gain and directivity of the DRA is 8.22 and 8.17dB respectively.
