Abstract

In this paper a novel multiport measuring system is presented. It allows for the measurement of both reflection and transmission coefficients. The system features an advantageous power distribution, which can be appropriately tuned in order to enhance the measurement accuracy. The system performance has been experimentally verified by S-parameters measurements of a bandpass filter. The obtained results are in a very good agreement with the values measured using a commercial VNA. Moreover, the measurement results clearly show that the tunable power distribution increases the measurement accuracy.
