Abstract :
A new improved six-port circuit for complex reflection coefficient measurements is presented. It consists of two six-port directional couplers. Assuming the components to be ideal, it is shown that the described six-port circuit has optimal properties for accurate determination of complex reflection coefficients. A six-port branchline coupler is briefly described.
