Abstract: Many women are affected by breast cancer, if not treated properly it can be fatal. This paper proposes a new dual band microstrip patch antenna with combination of hexogen and pentagon slots operating at 2.45 GHz and 4 GHz suitable for ISM and 5G application. The reflection magnitude S11 obtained at 2.45 GHz is -23.72 dB and at 4 GHz it is -15.04 dB. The proposed conformal antenna is printed on flexible 1mm thick PDMS substrate and can be applied for breast cancer detection. Simulations have been carried out with multiple antennas for tumour detection. The designed antenna has low SAR of 0.261 W/Kg with two antennas and 0.318 W/Kg with 6 antennas placed 5 mm off the body tested for 1 gm of tissue, well below the FCC specification of 1.6 W/Kg. The lower band antenna frequency can be used for detection of tumour and 5G bands suitable for faster transmission for further processing.
