Abstract :
In practice the symmetrical five-port junction in a six-port reflectometer set-up is nonideal in that it suffers from a residual mismatch. This theoretical study shows that, so long as the mismatch is small enough, the centres of the q-circles are still well spaced around the origin and the system can function satisfactorily as a practical reflectometer.
