Extensions of the Tseng-Cheng Pattern Synthesis Technique

The Tseng-Cheng distribution, applicable to a planar array with a rectangular grid and a rectangular boundary, and which gives a Dolph-Chebyshev pattern in every Ø -cut, is reviewed. It is shown that the limitation of equal numbers of elements in each direction can be lifted, and that not all ring side lobes need be at the same height. Null-filling is feasible, and the case of a flat top beam in every ø -cut, with controllable side lobes, is emphasized because of its potential importance in communication satellite applications.
