Description A compact wideband rectangular dielectric resonator antenna (RDRA) is investigated and presented. Perforations improve bandwidth by lowering down the quality factor. The perforations are an array of symmetrical square-shaped slots drilled uniformly on the RDRA. On choosing the optimal size of slots and distance between two consecutive slots, the fundamental mode of the RDRA is preserved. This aids in making the geometry compact by employing edge grounding. The coaxial probe acts like a monopole that further improves bandwidth by matching, monopole, and higher-order TE131-like mode of theRDRAin the frequency band (2.72-4.3 GHz). The proposed geometry offers a wide impedance bandwidth of 56% for S-11 < -10 dB. The measured results show that the radiation efficiency of the proposed antenna is above 85% for the complete bandwidth with the stable radiation pattern.
