Sažetak
The reflection coefficient measurement technique using a three-probe reflectometer was analyzed. Based on the results of the theoretical analysis, a very simple and low cost automated stepped frequency six-port reflectometer in the 7 GHz band was designed and manufactured. A six-port network was fabricated using a simple three-probe hybrid waveguide-coaxial structure and "off the shelf" waveguide components. An automatic measuring system was implemented by adding sweep generator and commercial power meters controlled by a PC computer. Calibration was implemented using the modified Neumeyer method. Measurements were made using few unknown loads and the achieved accuracy was 3% in magnitude and 1degree in the phase in the whole waveguide band. It was in good agreement with the theoretical prediction.
