Unidirectional Dielectric Resonator Antenna Using 3‐D‐Printed Uniaxial Anisotropic Ceramic
IET Microwaves, Antennas &Propagation, Volume 19, Issue 1, January/December 2025.The design of a Huygens source dielectric resonator antenna (DRA) exploiting artificial uniaxial anisotropic ceramic is presented. In practice, the dielectric resonator (DR) is made up of periodic anisotropic unit cells on a subwavelength scale and fabricated using a three‐dimensional (3‐D) printer. A prototype is finally designed and validated through
