Design of a large-aperture lens antenna usable over a +/- 15 deg scanning sector
A lens antenna design is described which requires the formation of both on-axis and far off-axis beams. The aperture is about 100 wavelengths in diameter, and the off-axis beams are displaced +/- 20 beamwidths from the axis. The results are indicative of the much greater scan capabilities of lensati...

| Zusammenfassung: | A lens antenna design is described which requires the formation of both on-axis and far off-axis beams. The aperture is about 100 wavelengths in diameter, and the off-axis beams are displaced +/- 20 beamwidths from the axis. The results are indicative of the much greater scan capabilities of lensatic antennas compared to paraboloidal designs when both have single-aperture nonarray feeds. |
