Abstract :
Using the moment method, a wire antenna array pattern is expressed in a form similar to that of a point source. The synthesis is thus reduced to that using well-known methods. The method is applied to linear as well as to planar arrays. Examples presented for several arrays how excellent agreement between the desired and the resulting patterns. The uncorrected patterns (without taking into account the mutual coupling) give similar results to the desired ones for arrays with many dipoles and equidistance greater than 0.50 λ. A method to improve the uncorrected pattern is proposed that is based on the addition of two parasitic elements
