Dielectric Resonator Antenna on Finite Ground

Calculate the input impedance and radiation pattern of a dielectric resonator antenna (DRA) with a coaxial pin feed on a finite ground.

Model the dielectric layers using the following configurations:
  1. Feed with a FEM modal source and solve using the hybrid finite element (FEM) and MoM solution.
  2. Feed with a waveguide source and solve using the method of moments (MoM) solution with the surface equivalence principle (SEP).
