Abstract :
The performance of a 3-foot-diameter circularly polarized metallic lens antenna at 
-band frequencies is described. The measured antenna gain, efficiency, half-power beamwidth, sidelobe level, and optimum focal length were determined for both on-axis and scan conditions. The effect of different lens illuminations for the on-axis case was ascertained.
