A new technique has been shown to enhance the bandwidth of a simple cylindrical dielectric resonator antenna (CDRA) using drilling holes. Firstly, studies have been carried out on simple CDRA which shows an impedance bandwidth of 53.8%. The bandwidth enhancement is due to the combination of HEMna and HEMm. Further, analysis has been done by drilling holes at different locations in same CDRA. Finally, the same CDRA with three holes simultaneously shows an impedance bandwidth of 70.70%. © 2016 IEEE.
