Flexible Wearable Antenna for Body Centric Wireless Communication in S-Band

Passive Microwave Imaging (PMI) has been widely studied for breast cancer detection in recent times. Sensing dielectric property differences of tissues over a wide frequency band has been made possible by ultra-wideband (UWB) techniques. In this paper, a flexible, compact monopole antenna on a Kapton polyimide is designed and fabricated, using a Computer Simulation Technology simulator (CST) and MEMS technology, to be in contact with biological breast tissues over the S-Band (2-4 GHz). The antenna parameters are optimized to obtain a good impedance match over the required frequency range. The operation of the antenna close to the human body necessitates adjusting its design for the intended applications whereas the maximum SAR value estimated in such conditions has to respect the standards. In this context, simulation tools that can take into account specific biological models offer a range of possibilities for investigating and optimizing the performance of Body-Centric Wireless Networks (BCWNs) devices.
