Optimizing radiation pattern and sidelobes in a genetic wire array

This paper presents numerical design models and predicted performance for a parasitic dipole antenna array tile that contains multiple feeds. This tile is designed for end-to-end concatenation with identical tiles to construct a phased array with a large number of feeds. The tile is optimized so that the radiation pattern of each feed is similar to the desired radiation pattern. The tile is simultaneously optimized so that the array exhibits low sidelobe levels for a range of scan angles.
