This study presents a design of dielectric resonator antenna with filtering capability at C-band. The antenna design consists of dielectric substrate on which a dielectric material with permittivity of 10 is designed to work as radiated element. A pair of separated aperture coupling slots are etched on the ground plane to couple the microstip feed line to the top dielectric material. Open stub with microstip feedline is designed for filtering function. The proposed antenna can achieve a wide bandwidth of 456.5 MHz in the range from 4.8911-5.3476 GHz. High order harmonic suppression and low order harmonic suppression are achieved which improve the antenna filtering response. The antenna can achieve a gain of 6.34 dBi, return loss <-25 dB and VSWR of 1.1 dB. The proposed dielectric resonator antenna has high performance with good filtering response which is useful feature in modern wireless communication systems.
