An experimental study concerning Ultra Wideband (UWB) Microwave Radar for breast cancer detection is described. A simple phantom, consisting of a cylindrical plastic container with low dielectric constant material imitating fatty tissues and a high dielectric constant object emulating tumour, is scanned with a tapered slot UWB probe antenna between 3.1 to(More)
A theoretical and experimental study of a novel image reconstruction algorithm for an Ultra Wide band (UWB) Microwave Imaging System aiming at detecting and locating small targets in a homogenous circular cylindrical dielectric body is presented. The system uses a double circular scan in which the second scan is achieved after rotating by a small angle the(More)
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(More)
—The design of compact wideband microwave reflectometers for the purpose of inclusion in a breast cancer detection system is presented. In this system, a wideband frequency source is used to synthesize a narrow pulse via the step-frequency synthesis method. The reflectometer undertakes measurements in the frequency domain and the collected data is(More)
