12 Dielectric resonator antenna on finite ground
Keywords: dielectric resonator antenna, radiation pattern, far field, input
impedance, infinite ground, FEM current source
The input impedance and radiation pattern of a dielectric resonator antenna on a finite
ground plane are considered in this example. The dielectric region of the antenna element
and feed is solved using FEM while the MOM is used for the ground plane and to model
the infinite radiation space. A layer of air is included in the FEM region to minimise the
number of triangles on the MoM/FEM interface.
