Abstract

A singleโ€fed circularly polarized dielectric resonator antenna is analyzed numerically. The element is a perturbed rectangular dielectric resonator excited by a coaxial probe and is used in a fourโ€element planar array. Different arrangements and excitations for the elements are used to study their effect on the circular polarization bandwidth. The circular polarization (cp) bandwidth for the sequential rotation feeding is found to be the best method and the broadside radiation cp is frequency independent. ยฉ 2003 Wiley Periodicals, Inc.

In this study, we report two four-element linear broadside arrays shaping the E and E field components. The radiating elements are probe-fed cylindrical dielectric resonator antennas. The arrays are analytically formulated, numerically simulated, and experimentally tested. The resonant frequency, ra
