Abstract
Conference Title: 2017 7th International Conference on Modeling, Simulation, and Applied Optimization (ICMSAO) Conference Start Date: 2017, April 4 Conference End Date: 2017, April 6 Conference Location: Sharjah, United Arab Emirates Vivaldi antenna provides ultra-wideband (UWB) performance that makes it attractive for several applications. In this paper, a Vivaldi antenna is designed for use in hyperthermia treatment as well microwave imaging. The focus is related to treatment and imaging of tumors in the human brain. The structure is optimized to obtain suitable gain and bandwidth while minimizing the size. Several parameters are investigated including the return-loss and radiation patterns. The results demonstrate that this configuration has potential in some biomedical applications.
