摘要:A deterministic procedure to design a nonperiodic
planar array radiating a rotationally symmetric pencil beam pattern
with an adjustable sidelobe level is proposed. The elements
positions are derived by modifying the peculiar locations of the
sunflower seeds in such a way that the corresponding spatial
density fits a Taylor amplitude tapering law which guarantees
the pattern requirements in terms of beamwidth and sidelobe
level. Different configurations, based on a Voronoi cell spatial
tessellation of the radiative aperture, are presented, having as
a benchmark the requirements for a typical multibeam satellite
antenna.
