Influence of dielectric loading on the fidelity factor of an ultra wideband monopole antenna

Anja Skrivervik, Nuno Miguel Faria Pires, Mohsen Koohestani

This paper reports a study of the influence on the fidelity factor due to loading an Ultra wideband monopole with a pair of dielectric substrate pads. The fidelity factor was calculated, with and without loading, using the simulated transmitted and receive ...
