A monopole antenna loaded by a hemispherical dielectric resonator

摘要

The input conductance, radiation pattern, and radar cross section (RCS) of a monopole loaded by a hemispherical dielectric resonator (DR) are studied. The effects of the DR on the monopole characteristics are investigated. Measurements were carried out to verify the theory. It is found that the input conductance, radiation patterns, and RCS are strongly affected by the DR.
