Additive Manufacturing of a Uniaxial Anisotropic Dielectric Material for Antenna Applications

International audienceIn this paper, we propose a procedure to design a uniaxial anisotropic dielectric material by additive manufacturing of ceramics. Such materials may find interesting applications in the design of dielectric resonators. As an example, a single-fed circularly polarized dielectric resonator antenna exploiting dielectric anisotropy is detailed. We propose a unit cell that constitutes the required uniaxial anisotropic material. Simulation results based on the antenna performances using an ideal anisotropic material and a periodic structure of several unit cells are also compared, showing a good agreement
