Analysis and design of circular antenna arrays by matrix methods

The antenna arrays considered in this paper consist of identical parallel dipoles equally spaced around and perpendicular to a circle. Application of the "method of moments" to the analysis problem yields a matrix description of the array. Economies of computation are achieved by exploiting the array symmetries. The matrix description of the array leads to a network description for feed design and a relationship between principal

-plane pattern synthesis and pattern synthesis for an array of point sources. Some classes of pattern synthesis problems are considered and calculated examples presented.
