Higher-Order-Mode Triple Band Circularly Polarized Rectangular Dielectric Resonator Antenna

The paper presents a triband circular polarized rectangular dielectric resonator antenna. A single coaxial cable feeds the DRA to double stub strip on side. patch coupled feed assists in widening bandwidth of proposed DRA. degenerate mode pair TE∂11x and higher-TE∂23x has been excited achieve CP enhance antenna gain. higher-order using low-cost simple excitation mechanism without compromising size shape An impedance 48% with gain ~6–9 dBic was achieved all resonance frequencies. Additionally, AR 5.5%, 4.2%, 2.76% obtained at three different Note that exhibits wide beamwidth 112o, which is good for better signal reception. comparison between measured simulated results shows are matched by result trends.
