RIDGE WAVEGUIDE RADIATORS FOR MISSILE ANTENNA APPLICATIONS
Abstract
Ridge waveguide antennas are radiating structures consisting of a waveguide with a movable center ridge. Movement of the ridge changes the phase velocity of the electromagnetic energy in the waveguide, the emergent radiated beam being thereby scanned in the elevation plane. The angle of the beam, which radiates through transverse shunt slots, is controlled by mechanically varying the height of the ridge. SuchANTENNAS ARE STRUCTURALLY SUITABLE FOR FLUSHMOUNTING ON THE CYLINDRICAL SECTION OF A MISSILE. Judging from th range of the scan angle, simplicity of construction, and ease of operation, the T-ridge waveguide is apparently more satisfactory than the rectangular- and semicircular-ridge waveguides.
