An enhanced hybrid-tee coupler ("EHT-coupler"), the EHT-coupler is described. The EHT-coupler includes a first waveguide, second waveguide, third waveguide, and fourth waveguide. The first waveguide defines a first port and the second waveguide defines a second port. Similarly, the third waveguide defines a fourth port and the fourth waveguide defines a fourth port. The first, second, third, and fourth waveguides meet in a single common junction and 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. The EHT-coupler also includes a first impedance matching element positioned in the common junction where the first impedance matching element includes a base and a tip.
