A low cost efficient reflectometer

This paper presents an efficient low cost reflectometer for microwave vector measurements using a four-port reflectometer with a single power detector. Two different systems are proposed to find the reflection and transmission coefficients. The system has been validated in two different frequency bands at 2 GHz and 94 GHz. The comparisons of measurement results with those obtained by the six-port technique prove the validity and the efficiency of this reflectometer.
