Novel hexagonal pizza shaped CPW microstrip patch antenna for applications in X band

A hexagonal pizza shaped microstrip patch antenna for breast cancer tumour detection is proposed in the paper. The antenna is designed to radiate frequencies in a narrowband centred at 9.3 GHz with a return loss of −23.94 dB with a bandwidth of 0.17 GHz (9.21 GHz–9.38 GHz). The antenna has the ground and the patch on the same plane making it a coplanar wave guide antenna. The basic theory and design has been analyzed, and simulation using HFSS commercial software has been employed to optimize the antenna. The antenna has been analysed for various dimensions of slots and the optimum design has been chosen based on slot dimension calculations.
