EBG based Microstrip Patch Antenna for Brain Tumour Detection

Abstract
A Microstrip patch antenna is designed using CST software to detect and visualize tumour inside the human brain. The design was carried out successfully by choosing the desired materials and dimensions for patch, feed line, ground and substrate. The materials used for patch, ground and feed are Perfect Electric Conductor (PEC) and FR-4 (Flame Retardant level 4) material for the substrate. The simulation results obtained from CST software for the above design for return loss at frequency 7.27GHz is -14.525dB and the maximum realized gain is 4.14dB. To intensify the performance of the Microstrip patch antenna and to effectively produce an acceptable SAR which reliably indicates the presence of tumour inside the human brain, a compact and efficient Microstrip patch antenna is designed by embedding circular Electromagnetic Band Gap (EBG) structure on the antenna ground plane. By doing so, the simulation results obtained from the CST software for return loss at frequency 7.3GHz is -16.07dB and the maximum realized gain is 6.48dB. It is inferred that for 2.75mm which is the length of feed proper impedance matching is obtained at resonance frequency 7.39GHz and the return loss is -26.317dB. The maximum SAR achieved is 541W/m3.
