Method For Forming A High Frequency Antenna
Method For Forming A High Frequency Antenna
US Patent:
4047287, Sep 13, 1977
Filed:
Feb 18, 1975
Appl. No.:
5/550629
Inventors:
Howard H. Hubbard - Scituate MA
Thomas P. Walsh - Marshfield MA
Thomas P. Walsh - Marshfield MA
Assignee:
Antennas for Communications, Inc. - Ocala FL
International Classification:
H01Q 1700, B28B 710
US Classification:
29600
Abstract:
A method for forming a high frequency antenna such as a horn-reflector antenna. In fabricating the horn antenna a mold may be used which comprises a paraboloid-cylindrical section and a pair of half cone shells for forming respectively the paraboloid-cylindrical portion and the cone portion of the antenna. In assembling the mold, the shells are secured together and then the cylindrical section is fastened to the assembled shells. After the antenna has been formed, the mold is disassembled by first removing the paraboloid-cylindrical section, thereafter removing one of the shells and then the remaining shell; and all such mold parts being removed via the radiating aperture of the paraboloid-cylindrical portion of the antenna.
