Abstract

An waveguide circulator including at least three waveguides and a centre section. The waveguides are cross-coupled in the centre section. In the centre section a ferrite element is arranged. The circulator has means for magnetising the element. One of the waveguides has at least one constriction element in its interior. The constriction element is arranged to reduce leakage signals arising from imperfections in the circulator.
