Abstract

A cylindrical dielectric resonator antenna (CDRA) fed by nonresonant microstrip patch excites HEM_12δ mode for efficient radiation. A 2 × 2 antenna array with such an antenna element is designed at the center frequency of 9.04 GHz for obtaining higher directive gain. A prototype has been fabricated with FR-4 substrate, and experimental measurements have been carried out. The array offers an impedance bandwidth of 2.9% and a maximum gain of 14.8 dBi at the operating frequency. A good agreement has been obtained between the measured and simulated results.
