A U-shaped dielectric resonator antenna (DRA) excited by an elliptical patch is presented for broadband communication applications. By using the combination of a Ushaped homogenous dielectric resonator and a conformal elliptical patch on the back-side surface of the resonator as a feeding mechanism, a 72% impedance bandwidth (S11= -10dB), covering the frequency range of 3.82 - 8.12 GHz is achieved, with a stable radiation pattern.
