Abstract
An array of flared horn antennas is adapted to be fed from circular waveguide. The apertures of the horns are closely spaced. Prior art horns with circular apertures leave gaps in the aperture. The gaps are eliminated, and the gain of the array is increased by about 1/2 dB by tapering the horns from a circular cross-section at the feed end to a hexagonal cross-section at the radiating aperture end.
Claims8
An antenna array comprising:
- a plurality of flared horns, each of said flared horns including a smaller feed end and a larger aperture end, each of said flared horns being adapted to be coupled to one of a plurality of circular waveguide ports for receiving signal to be transmitted, each of said flared horns having a circular cross-section at said feed end and a regular hexagonal cross-section at said aperture end and a taper therebetween;
- and
- mounting means coupled to said plurality of flared horns for arraying said plurality of flared horns with said aperture ends contiguous.
An antenna array, comprising:
- a plurality of flared conductive horns, each of said flared horns including a smaller feed end having a circular cross-section and also including a larger radiating aperture end, said radiating aperture ends being closely spaced with the radiating apertures of a maximum number of adjacent flared conductive horns, whereby if the cross-sections of said flared conductive horns at said radiating aperture end were to be circular, the array would have interstitial gaps which would reduce the gain of the array;
- and
- a transition associated with each of said flared conductive horns, said transition being between said circular cross-section at said feed end and a regular hexagonal cross-section at said radiating aperture end, whereby when said radiating aperture ends of said flared conductive horns are closely spaced, said interstitial gaps are substantially eliminated and the gain of said array is increased.
An antenna array comprising:
- a plurality of horns having hexagonal cross-sections at their radiating apertures;
- mounting means for mounting said plurality of horns with their apertures closely spaced;
- and
- feed means coupled to said plurality of horns for transducing energy.
