Circular antenna array design for breast cancer detection

Microwave imaging for breast cancer detection is based on the contrast in electrical properties of healthy fatty breast tissues. This paper presents, an industrial scientific and medical bands (ISM) comparative study of five microstrip patch antennas for microwave imaging at 2.45GHz frequency, a choice of one antenna is made for an antenna array composed by 8 antenna for a microwave breast imaging system, each element are arranged in a circular configuration, so as that every antenna element can be directly faced to the breast phantom for better tumor detection. This choice was made by putting each antenna alone on the Brest skin to study electric field, magnetic fields and current density in the healthy tissue of the breast phonton designed and simulated in Ansoft High Frequency Simulation Software (HFSS).
