摘要：
In this paper, three methods to retrieve the effective permittivity of 3D -printed unit cells for dielectric resonator antenna (DRA) applications are compared: Maxwell Garnett approximation (MGA), S -parameters method, and plane wave expansion method (PWEM). More specifically, three common topologies are studied: simple cubic (SC), body -centered cubic (BCC) and face -centered cubic (FCC). From numerical analyses, we explain which method is the most appropriate for designing a DRA using 3D -printed periodic unit cells.
