Phased Array Scan Performance Review for SATCOM: Dielectric Resonator vs. Patch Antennas

A comparison of arrays employing dielectric resonator antennas (DRA) and patch antennas as elements is presented. The bandwidth of the arrays under study is over 40% at broadside, covering the K/Ka-band SATCOM and mmWave 5G bands. The element analysis is performed for the principal planes in an infinite array environment. Numerical results suggest the scan performance of DRA phased arrays is limited by the dielectric loading of the array aperture.
