Tumor detection by microwave radar imaging system

Abstract

In this paper, we describe the design of an ultra wide band (UWB) system for microwave imaging system, using monopole antenna fed by a 50 Ω microstrip line, operating over 1.416 – 9.367 GHz band. To meet the requirements of the specifications of our application, some bandwidth enlargement techniques have been introduced such as: the insertion slots, and the use of partial ground plans. A simple breast and tumor models have been developed and simulated under CST software. Finally, we have implemented the delay and sum Integration algorithm for microwave imaging to detect a small tumor (radius = 5 mm).
