Brain Tumor Detection with Compact Monopole Antennas using Microwave Medical Imaging

In this work, a star shaped patch with an outer ring structure is designed in the simulator for microwave head imaging applications. The designed antenna operatres from 1.47 GHz to 4.7 GHz with an impedance matching of greater than 10 dB. The antenna attains a peak gain of 3.8 dBi at 4.3 GHz. The Specific Absorption rate (SAR) of the designed antenna is checked to evaluate the effect of the antenna on the human head. This is done by separately designing a 7 layered head phantom. The antenna is also utilized to image brain tumor by introducing a cancerous tumor inside the brain phatom for imaging. Finally, brain tumor is obtained successfully after imaging using widely popular Delay and Sum (DAS) algorithm.
