ULTRA-WIDE BAND ANTENNA DESIGN TO IMPROVE DETECTION IN MICROWAVE IMAGING

Abstract

In this research, a UWB antenna is designed for breast cancer detection. The technology on which it works is microwave imaging. The frequency range is between 1.5GHz-6.5GHz spectrum which meets the requirements of our application that is UWB antenna for tumour detection and other medical applications, especially for breast cancer detection. The material used for fabrication is Rogers TMM 3 and the tool in which the antenna design is simulated is FHSS. As to enhance the performance of the antenna several modification and techniques are used i.e. slot insertion and Bezier curve. This tends to improve the Gain, Return loss S11, Directivity and radiation pattern of the system. To increase the total gain of the system a symmetric array of size 2 x 5 of monopole pattern arrangement. This combination achieves better results in terms of the target parameters as compare to the previous work that runs on asymmetric array having hemispheric arrangement.
