Optimized symmetric discrete line arrays

A generalization of Dolph's method for the synthesis of discrete antenna arrays is applied to six different symmetric line arrays. Based on these examples, it is concluded that 1) the field patterns of optimized symmetric line arrays with the same number of elements and with the same aperture are virtually indistinguishable and 2) optimized arrays with an odd number of elements are substantially better, in general, than arrays with an even number of elements.
