Detection of Human Brain Tumors Using an UWB Patch Antenna at 28GHz

It is proposed to design and utilize a strip line inset fed Ultra-Wide Band (UWB) patch antenna having a bandwidth of 7GHz resonating from 23GHz to 30GHz in order to identify the existence of tumor inside a human brain. A six layered healthy brain model has been designed and a 5mm radius tumor is positioned inside the brain model. A comparative analysis of radiation properties of patch antenna for a normal healthy and a tumor induced brain model has been done. The comparative analysis of performance metrics of the proposed patch antenna viz. bandwidth, directivity, gain, return loss, voltage standing wave ratio and electric field intensity for both the brain models has been done. According to the results, a brain model with a tumor has a greater SAR than a brain model with a healthy brain. Based on the obtained results, the proposed patch antenna could potentially be utilized for detection of tumor in human brain.
