N2 - A novel broadbeam aperture-coupled coplanar parasitic rectangular dielectric resonator antenna is proposed which yields broadbeam in both working planes simultaneously. The antenna consists of a main radiating rectangular dielectric element centered over a wide feed slot and two parasitic rectangular dielectric elements one on each side of the main radiating element with an optimum gap in between. The dielectric height and wide slot both play an important role in enhancing the beamwidth in two principal planes simultaneously. It is validated that inclusion of parasitic elements enhances the broadbeam bandwidth in addition to frequency bandwidth. First three azimuthal modes are excited out of which first two modes TEx 111 and TEx 112 are desired. The proposed antenna is compared with single element rectangular dielectric resonator antenna. To validate the proposed design, a prototype is fabricated and measured. The simulated and measured operating frequency bands of the proposed antenna respectively are 4.8 to 6.9GHz and 5 to 6.8GHz. The measured E- and H-plane beamwidths range from 115° to 144° and from 115° to 124°, respectively, yielding a wider coverage area.
