“…In [6][7][8][9][10], single-band DRA with circular polarization is achieved by including the patch at the corner of the DRA structure. In the circular polarized [CP] DRA is presented for tri-band operation, the hybrid DRA with loop modification is used to achieve the CP.…”

“…But the major disadvantage of microstrip is the low bandwidth and radiation efficiency. Metamaterials, [3,4,6,7] subwave length structures with unconventional electromagnetic traits like negative permitivity, permeability, and refractive index, have captivated researchers in recent decades. These properties, stemming from structure rather than constituents, enable novel electromagnetic device design.…”

The hybrid Dielectric Resonator Antenna (DRA) with circular polarization is another key research area since it can provide better antenna characteristics required by modern-day communication standards than the DRA with linear polarization. In this article, a Hybrid rectangular DRA is proposed. The Proposed DRA is excited with a novel feeding structure which is the combination of apex etched rectangular monopole and microstrip feed. The feeding structure is printed on a material with a dielectric constant of 4.4. The DR of 9.8 dielectric constants is placed on top of the patch. The proposed structure resonates at four different bands 1.42-1.52 GHz, GHz. The Critical parameters are analyzed and optimal dimensions are identified using the CST software. The proposed antenna exhibits circular polarization, which is validated with the axial ratio and electrical field distribution. The simulated results of the surface current are presented to validate the performance The measurement result is compared with the simulated results and found to be in agreement. The gain is well maintained above 1.5 dBi in all the resonating bands. A stable radiation pattern across all the resonating bands is achieved.
