Abstract
The potentially broad application area in engineering design using Genetic Al-
gorithm (GA) has been widely adopted by many researchers due to its high consistency and
accuracy. Presented here is the initial design of a wideband non-dispersive wire bow-tie antenna using GA for breast cancer detection applications. The ultimate goal of this design is to achieve minimal late-time ringing but at higher frequencies such as that located from 4 to 8 GHz, in which is desire to penetrate human tissue for near field imaging. Resistively loading method to reduce minimal ringing caused by the antenna internal reflections is implemented and discussed when the antenna is located in free space and surrounded by lossy medium. Results with optimised antenna geometry and diĀ®erent number of resistive loads are presented and compared with and without existence of scatterers.
