Circularly Polarized Huygens Source Antenna Based on Two Stacked Dielectric Resonators

In this paper, a cross-shaped dielectric resonator antenna arranged in a stacked configuration is proposed to realize a Huygens source in circular polarization at 2.45 GHz ISM band. The antenna principle relies on the combination of two pairs of orthogonal electric and magnetic dipoles. The antenna is designed and optimized with numerical analysis using far-field simulations in Ansys HFSS. It finally has a radiation pattern oriented in one half-space without the use of a ground plane.
