Abstract

This work presents the design and development of a miniaturized compact UWB antenna for wireless body area networks (WBANs). The working of ultra-wideband (UWB) antennas and their notch characteristics are explained by considering several cases. First we consider a simple rectangular micro strip patch antenna and then improve its bandwidth by applying available UWB techniques; additionally, we discuss UWB antennas in WBANs and the importance of having band rejection characteristics. We consider another fractal-based miniaturized UWB antenna with notch characterizes using metamaterial-based unit cells etched from either ground or radiating elements to act as a filter section. Comparative illustrations are given with the help of reflection curves, voltage standing wave ratio, and specific absorption rate analysis.
