Abstract
Provided herein are various enhancements for waveguide structures and magic tee arrangements in radio frequency aperture antenna feed structures. A waveguide structure includes a waveguide cavity coupling colinear ports, a difference port, and a sum port, with the sum port disposed perpendicularly to both the difference port and the colinear ports. The waveguide structure also includes an impendence matching element comprising a triangular body disposed in the waveguide cavity and protruding perpendicularly from a wall of the waveguide cavity between the colinear ports.
Claims20
A waveguide structure, comprising:
- a waveguide cavity coupling colinear ports, a difference port, and a sum port, with the sum port disposed perpendicularly to both the difference port and the colinear ports;
- and
- an impendence matching element comprising a right triangular body having a hypotenuse face positioned toward the difference port and the sum port, disposed in the waveguide cavity, and protruding perpendicularly from a wall of the waveguide cavity between the colinear ports.
A method, comprising:
- forming a waveguide structure by at least:
- forming a waveguide cavity coupling colinear ports, a difference port, and a sum port, with the sum port positioned perpendicularly to both the difference port and the colinear ports;
- and
- forming an impendence matching element comprising a right triangular body having a hypotenuse face positioned toward the difference port and the sum port, disposed in the waveguide cavity, and protruding perpendicularly from a wall of the waveguide cavity between the colinear ports.
