Circularly Polarized Dielectric Resonator Antenna With Two Annular Vias
IEEE Access, 2021 In this paper, a new technique for circular polarization in a slot coupled dielectric resonator antenna is proposed. The circular polarization is generated by inserting the two annular vias into dielectric resonator slightly off the diagonal position. In
