Abstract
In this paper we propose and investigate the application of Electromagnetic Band Gap (EBG) substrate for improving the performance of Hemispherical Dielectric Resonator Antenna (HDRA). Our designed EBG shows a band gap in the frequency range of 1.75–2.25 GHz and the HDRA is resonant at 2 GHz which falls within the bandgap of the EBG. When combined with the EBG substrate the −10 dB bandwidth shows an improvement from 11.25% to 30%. On engineering the height of the HDRA on EBG substrate the gain is improved from 6.13 dBi to 9 dBi. To validate the results, simulations are carried out on CST Microwave Studio and HFSS.
