Abstract :
Two very simple and low-cost single six-port reflectometers designed using the waveguide technique (IEC R220 and R320) are described. They consist of only a waveguide coupling structure and a directional coupler. They allow the complex reflection coefficient to be measured with small uncertainties. The calibration of the reflectometers is discussed, arid results obtained with the R320 reflectometer, showing the precision of the instrument, are presented.<>
