Cancer detection using microwaves is one of the most promising and attractive screening techniques which is currently under research. This technique offers several advantages such as low cost, better patient comfort, non-ionizing and non-invasive compared to diagnostic imaging modalities which have been available more than a decade to detect the breast cancer like X-ray mammography, ultrasound and MRI. In this work, an optimized circular patch antenna is designed in CST Microwave Studio to achieve the better trade-off between the depth of penetration and spatial resolution. The proposed patch antenna resonates from 1.5 to 7.1 GHz with the voltage wave standing ratio (VSWR) value less than 2. Other parameters like gain, directivity and specific absorption rate (SAR) are evaluated to check the performance of the antenna. The designed antenna and breast phantom with tumor of 5 mm are simulated in the CST environment. The reflected signal from the phantom is then processed to identify the presence and location of the tumor using scattering parameter (S11).
