Abstract

Embodiments of the invention provide a hybrid tee waveguide structure including a first collinear arm having a first waveguide, a second collinear arm having a second waveguide, an H-arm having a third waveguide and including at least one window; and an E-arm having a fourth waveguide and including at least one window, the E-arm oriented perpendicular to the H-arm. The first, second, third and fourth waveguides join at a common junction. The at least one window of the H-arm and the at least one window of the E-arm are proximate the common junction. The at least one window of the H-arm and the at least one window of the E-arm change an impedance of the common junction to reduce reflections in the H-arm and E-arm. The hybrid tee waveguide structure further includes an impedance matching element positioned in the common junction.
