Abstract

Abstract This paper presents electrical equivalent circuit modelling of various fractal-based UWB antennas. Three different designs have been discussed here as case studies, whose characteristics are diversified in nature. Even the implemented fractal geometries are also unique in nature for these antenna problems. An easy circuit model for each antenna structure is proposed which deciphers the insight device physics of the structure. Without applying much more complicated mathematical jugglery, the models have been presented here. Finally, a comparison of FEM simulated data and the result obtained from circuit modelling is concluded, which establishes the validity of the proposed models.
