This paper presents a broadband antenna array pattern synthesis technique with the capability to steer a main beam of specified frequency response in a desired direction without presteering the array. Sidelobes are controlled using a weighting function in the integrated power response of the array in such a way that the array response drops as the distance from the look direction increases. Using this technique one is able to achieve a beam of very low sidelobes. Examples are presented to show the effectiveness of the method in designing a broadband antenna array.
