  • ANTENNA FEEDHORN WITH ONE-PIECE FEEDCAP
    Publication number: 20130342412
    Abstract: An antenna for use with electromagnetic waves includes a waveguide body having an open end and first threads and a cap having second threads which interface with the first threads to press the cap against the open end. The cap includes a cover which covers the open end when the cap is screwed onto the open end using the first and second threads while allowing the electromagnetic waves to pass through the cover. The antenna can be a horn antenna, and can also be a feedhorn antenna used with a reflector in a reflector antenna.
