Abstract
An improved feed horn for use with long f/D reflector antennae comprising an aperture having a plurality of protuberances orthogonally disposed around the periphery thereof, a conical section, a waveguide transition section and an impedance matching section.
Claims6
An electromagnetic feed horn for use with antenna reflectors in a waveguide transmission system, said feed horn comprising:
- an aperture for receiving electromagnetic waves, including a plurality of protuberances symmetrically disposed radially outward along the periphery thereof and orthogonal to the direction of propagation of said waves;
- a conical section coupled to the aperture for receiving electromagnetic signals therefrom;
- a waveguide mount for mounting the feed horn to the waveguide transmission system;
- an impedence matching section coupled to the waveguide mount, for matching the electromagnetic signal impedance of the feed horn to the waveguide system;
- and
- a waveguide transition section for coupling the conical section to the impedance matching section and for converting energy received from the conical section to signals propagating in a waveguide mode.
