Abstract :
The performance of a hexagonal array of radiating elements fed by a rectangular lattice of identical row and column boards of Rotman lenses is described. The resultant beams with high directivity and good isolation are arranged in a hexagonal lattice that is rotated 90/spl deg/ from the element lattice.
