On a pattern synthesis method for a linear array

A pattern synthesis method for a linear array which produces a desired radiation pattern is obtained by using the integral mean of its Fourier approximation. According to the method, the properties of a realized pattern can be easily controlled by two newly introduced parameters; one is determined by the number of elements, the beam width constant and the element spacing, and the other determines the weight function to the Fourier coefficient function. In this paper, a few charts with these two parameters for designing an antenna having some typical radiation patterns are presented with interesting examples. If a desired minor lobe level and a beam width are given, the optimum number of elements can be estimated from these charts. Finally this method is proved to be useful by experimental results.
