Abstract

A broad-beam U-shaped dielectric resonator antenna (DRA) is investigated for designs of wide-angle scanning phased array antennas. The U-shaped DRA, fed by an underneath slot, is placed in the middle of a ground plane. The fundamental mode of the DRA is merged with the slot mode, broadening the impedance bandwidth. The design was simulated, fabricated, and measured, and the measured results agree reasonably well with the simulated ones. A measured overlapping bandwidth of 10.2% (3.45-3.82 GHz) is obtained, with both the E- and H-plane 3-dB beamwidths being greater than 120° and| S₁₁| being less than -10 dB. © 2024 IEEE.
