Waveguide circulator with improved transition to other transmission line media

摘要

A waveguide circulator for an electro-magnetic field having a wavelength is provided. The waveguide circulator includes: N waveguide arms, where N is a positive integer; a ferrite element having N segments protruding into the N respective waveguide arms; at most (N−1) quarter-wave dielectric transformers attached to respective ends of at most (N−1) other segments; a first quarter-wave dielectric transformer attached to an end of the first segment; and a coaxial-coupling component. The N waveguide arms include a first-waveguide arm and (N−1) other-waveguide arms. The N segments include a first segment protruding into the first-waveguide arm and (N−1) other segments protruding into respective (N−1) other-waveguide arms. The coaxial-coupling component is positioned within a quarter wavelength of the electro-magnetic field from the first quarter-wave dielectric transformer positioned in the first-waveguide arm.
