چکیده
In this letter, we study the design of three-dimensional (3D)-printed ceramics exhibiting anisotropic dielectric permittivities at microwave frequencies for resonator antenna (DRA) applications. The anisotropy is engineered by using periodic structures made up subwavelength asymmetric unit cells filled with zirconia and air. Ceramic samples uniaxial are designed, 3D-printed, measured. Birefringence to 8 achieved controlling volume fill rate cell. Besides, a single-fed circularly polarised (CP) DRA that relies on 3-D-printed ceramic proposed in 2.45 GHz ISM band. Its simulated measured reflection coefficient, axial ratio, realised gain patterns good agreement, thus demonstrating possibility exploiting
