This paper describes the design and measured performance characteristics of a circularly-polarized fan-shaped beam antenna. It consists of a parabolic cylinder reflector, tilt-fed by a subsystem comprising a small conical horn and a circular waveguide transmission line containing a quarter-wave plate. Virtually exact-scale-model composite antennas were tested in detail over the 15.5- to 28-GHz and 24.9- to 41.7-GHz frequency bands. It is shown that in the lower 1.65:1 portions of these 1.8:1 bands all performance characteristics are quite favorable and that, thereafter, certain important performance characteristics rapidly deteriorate.
