Measurement Accuracy Enhancement in Six-Port Reflectometers

A new algorithm improving measurement accuracy in six-port reflectometers, applicable also for arbitrary multiport reflectometers, is proposed. The developed procedure does require neither additional measurements nor modifications of the measuring system. The introduced weighting coefficients allow for enhancement of the measurement accuracy using the same power measurements as in classic solutions. The proposed theory has been confirmed experimentally by the measurements of reflection coefficient within a wide frequency range 2-4 GHz.
