Abstract :
Planar reflectarray antennas with parabolic-torus phase distribution are investigated for high-gain beam-scanning applications. Analytical expressions for the reflectarray aperture phase distribution are derived for the generalized offset configuration. A Ka-band planar reflectarray with 30 dB gain and 40 degree scan coverage is demonstrated. The study reveals that planar reflectarrays with parabolic-torus phase distribution show a momentous promise for high-gain beam-scanning.
