Unidirectional Dielectric Resonator Antenna Using 3‐D‐Printed Uniaxial Anisotropic Ceramic
ABSTRACT A Huygens source dielectric resonator antenna (DRA) with unidirectional radiation pattern is presented. It consists of a coaxial probe exciting a rectangular, homogeneous and uniaxial anisotropic dielectric resonator (DR). To obtain a Huygens source radiation pattern, a pair of quasi‐TM and TE modes are combined by controlling the permittivity tensor of the DR. A prototype operating at 2.5 GHz has been designed. The DR is made up of periodic anisotropic unit cells on a subwavelength scale and fabricated using a three‐dimensional (3‐D) printer. The simulated and measured results are in reasonable agreement. A relative impedance bandwidth of and a front‐to‐back ratio larger than 15 dB at operating frequency are finally measured.
