A design of multiband hybrid-shape dielectric resonator antenna (DRA) is presented. In this design the dielectric resonator material (DR) is fed by 50Ω rectangular microstrip line arranged on top of a substrate. The antenna uses the defected ground structure (DGS) technique. Results are obtained using electromagnetic simulator to study the impedance bandwidth, radiation pattern, return loss and antenna gain. This proposed antenna is simulated obtaining four bands (4.04-8.016), (9.7-10.6), (11.48-12.48) and (14.16-15.16) GHz for S11 ≤ -10 dB, with resonated frequencies (4.6, 7.4, 10.2, 12.2, and 14.48) GHz and provides impedance bandwidth of (55.6%, 8.6%, 8.1%, and 6.9%) which can be employed in multiband applications, like WLAN, sub-6 GHz, X-band, and Ku-band.
