چکیده انگلیسی
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.
