The design of a wave-guide-fed array of slots to give a specified radiation pattern

It is well known that the distribution of amplitude and phase which is necessary across an aerial aperture to obtain a specified radiation pattern can be calculated by using the Fourier transformation. This paper describes a method by which any specified aperture distribution can be obtained from a wave-guide-fed array of slots. Thus the problem of obtaining a specified radiation pattern is solved. Experimental results are given to confirm the theory.
