Wideband microstrip patch antenna design for breast cancer tumour detection

Abstract

A patch antenna is presented which has been designed to radiate frequencies in the range 4–9.5 GHz into human breast tissue. The antenna is shown by means of previously unpublished simulation and practical measurements to possess a wide input bandwidth, radiation patterns that remain largely consistent over the band of interest and a good front-to-back ratio. Consideration is also given to the antenna's ability to radiate a pulse, and in this respect it is also found to be suitable for the proposed application.
