Synthesis methods for antenna arrays with non-uniformly-spaced elements

University of British Columbia

A study is made of some of the existing techniques for determining the positions and excitations of the elements in an array, in order to produce a desired radiation pattern. A new method based on numerical quadrature is proposed. Equal-sidelobe patterns are synthesized and a comparison of the methods is made on this basis. Results indicate that the proposed quadrature method is an improvement over the other tested methods in two ways, (i) it produces a more accurately synthesized pattern and (ii) it is simple to compute. It is therefore useful for synthesizing arrays containing large numbers of elements. However, for the particular radiation pattern selected, none of the methods gave an improvement over the corresponding uniformly-spaced array.
