| Summary: | The increasing growth in using body area networks (BANs), wireless personal area
networks (WPANs), and medical sensors has given an interest in wearable antennas
that are made for operation on the living bodies. Engineers have not stopped at
creating a remarkable technology such as wearable systems, but also involved in
understanding the interaction of electromagnetic (EM) waves with the body.
Studying the interaction between EM waves and the body requires modeling of the
body with physical phantoms or with numerical phantoms embedded in numerical
electromagnetic codes. In this project, two ultra-wideband (UWB) planar monopole
antennas have been reported in this thesis. The substrates of the proposed antennas
have been made of jeans while radiators were made of copper tapes. Simulated and
measured performances of the antennas in terms of return loss and radiation patterns
have been discussed in this work. Recorded results have shown that the operating
frequency ranges from 3.04 GHz to 10.3 GHz and from 3.04 GHz to 11.3 GHz with
respect to -10 dB for the first and second antennas respectively. The antennas have
been tested under severe conditions such as operating in water and aggregates, and
results have been presented and discussed. Moreover, an extended study on the
safety concerns of the antennas by means of specific absorption rate (SAR) has been
included in this work. The approximated SAR has been found to be within the safety
guidelines set by Federal Communications Commission (FCC). |
