Claim Text:
1. An enhanced hybrid-tee coupler (“EHT-coupler”), the EHT-coupler comprising: a first waveguide defining a first port; a second waveguide defining a second port; a third waveguide defining a third port; a fourth waveguide defining a fourth port; wherein the first, second, third, and fourth waveguides meet in a common junction, the first waveguide and second waveguide are collinear, the third waveguide forms an E-plane junction with both the first waveguide and the second waveguide, and the fourth waveguide forms an H-plane junction with both the first waveguide and the second waveguide; and a first means for impedance matching positioned in the common junction; a second means for impedance matching positioned at a first top wall of the first waveguide external to the common junction; a third means for impedance matching positioned at a second top wall of the second waveguide external to the common junction; a fourth means for impedance matching positioned at a third top wall of the fourth waveguide external to the common junction, wherein the first top wall and the second top wall are opposing waveguide walls that are opposite to the coplanar common waveguide wall, and the third top wall is an opposing waveguide wall that is opposite to the coplanar common waveguide wall; a fifth means for impedance matching positioned at a front broad wall of the third waveguide external to the common junction; and a sixth means for impedance matching positioned at a back broad wall of the third waveguide external to the common junction, wherein the front broad wall is opposite the back broad wall.
