Design of Components for a Compact Ultra Wideband Microwave Imaging System

The paper describes the design of hybrid circuits and antennas for a compact ultra wideband (UWB) microwave imaging system aimed at operation from 3.1 to 10.6GHz. The design of these components is accomplished with the use of full-wave electromagnetic field analysis and design software. The components are developed and experimentally tested. They show good electrical performances over the specified band and thus they are ready to be incorporated in the proposed configurations of an UWB microwave imaging system.
