dc.description.abstract The design of a wideband microwave reflectometer 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 frequency domain and the collected data is transformed into time/space domain using IFFT. In order to accomplish reflection coefficient measurements over a large frequency band, wideband couplers, dividers and square-low power detectors are required to form the six-port reflectometer. In this measurement equipment, voltages appearing at the detectors outputs can be processed with a PC equipped with precision Analogue to Digital converters. The chosen configuration of the six-port enables the display of the measured data in real-time. Its operation is studied with the use of Agilent ADS en_AU
