Forward V-band vector network analyzer based on a modified six-port technique

Abstract

A V-band forward network analyzer based on a modified six-port technique is proposed for the measurement of complex reflection (S11) and transmission (S21) coefficients. The millimeter-wave part of the system is implemented on a thin alumina ceramic substrate. The measurement performance is evaluated by comparing the results obtained from the system proposed to those given by a conventional network analyzer in the frequency band 55-65 GHz.
