Microwave Medical Imaging using a Compact Monopole Antenna for Brain Tumor Detection

For microwave head imaging, a patch in the shape of a flower is created in this work using the CST Studio software. A matching performance of more than 10 dB is achieved between 1.59 to 5.2 GHz for the specified structure. When operating at 4.4 GHz, the antenna achieves an apex gain of 3.92 dBi. To determine the impact of the antenna on the human head, the SAR value of the designed antenna is examined. 7-layered human head model designed on software is used for this. The simulator is used to study each performance criterion for the proposed structure. Additionally, 11 copies of the intended antenna are positioned all around the designed head model to obtain sufficient data for imaging the embedded tumour.
