Abstract :
The iterative technique presented depends upon the solution of a set of simultaneous equations for perturbations of the element currents. Current distributions have been calculated which yield low sidelobe patterns from an array of 
elements with only 0.25 dB less azimuth directivity than an order 
Tchebycheff pattern that has the same sidelobe level.
