Use of Directional UWB Antenna for Lung Tumour Detection

Abstract

In this research, the use of directional UWB antennas for the purpose of lung tumour detection is investigated. A comparison of the performance of directional and non-directional UWB antennas in the detection of lung tumour is presented through simulations and it is shown that using a directional UWB antenna results in clear detection of tumor and also allows to increase the distance between the patient and the antenna to perform the test. The difference in the plots of S parameters of antenna for normal lung and cancerous lung provides the basis for the detection of tumour. These findings can further pave the way for manufacturing patient friendly microwave medical imaging equipment in future.
