Abstract

Probe-fed dielectric resonator antenna (DRA) arrays with hard horn excitation are investigated in an oversized dielectric loaded waveguide for their use in waveguide-based spatial power combining systems. The finite-difference time-domain (FDTD) approach with region-by-region discretization scheme is proposed for the analysis of the entire system. Numerical results for the scattering parameters are demonstrated for the example of 3 × 3 DRA array excited by a hard horn. A parametric study is presented in order to optimize the system for scattering and coupling characteristics.
