Abstract:

This report describes the fabrication and testing of a lens antenna that is designed to have wideband scanning capabilities for wide angle scanning in any plane. The lens has a 30 by 40 wavelength aperture. Far field patterns were measured in both azimuth and elevation planes over and eleven percent bandwidth. The azimuth scan angles were 0 deg, 15 deg, 30 deg and 45 deg and the elevation angles 0 deg and 15 deg. The quality of the patterns is fairly good with the average power level from 50 deg to - 50 deg close to 44 dB in the sidelobe region excluding the 7 or 8 close in sidelobes. These lobes have peak values about 30 dB. Author
