Abstract :
We present a general method to get distributions with minimal edge brightening (minimizing the mutual coupling problem ) in sum pattern synthesis. The method obtains patterns, in which the infinitely deep nulls are replaced by less deep nulls. This provides a multiplicity of solutions, one of which may be easier to achieve physically than the original solution. The solutions corresponding to linear and planar array synthesis show an important improvement in the distributions, without much loss im directivity for the resulting pattern.
