Abstract
An array-fed transmitarray is proposed to radiate various beams with designated directions and coverages. It is proposed based on the superposition principle. An array is used as the feed. When the feed sources are excited individually, multiple elemental beams pointing at different angles are generated. Then the expected beam can be obtained by adding up these elemental beams. The detailed and effective control of beam directions and coverages are put forward. Flattop beams and multi-beams with different coverages and directions are finally designed for validation.
