Analysis of a hemispherical dielectric resonator antenna with very high permittivity (/spl epsiv//sub r/ = 169)

The analysis of very high permittivity (/spl epsiv//sub r/-169) structure using WIPL-D, a software package for electromagnetic modeling of composite metallic and dielectric structures, is presented. As an example, a microstrip patch hat antenna is treated. Network parameters, radiation pattern and current distributions on the surface are analyzed.
