ABSTRACT:
A method for economically producing low sidelobe levels in the far field pattern of an array antenna is disclosed. The current fed to the subarrays is identically tapered to the elements of each subarray. Both the subarray current taper and the element current tapers are optimized to yield the lowest possible sidelobe levels.
