Abstract:

The report describes a way of designing a two-dimensional array to minimise the side-lobes while maintaining any given beamwidth of the radiation pattern in the array plane. The amplitudes and phases associated with the elements are adjusted by a modified gradient method which uses a linear programming procedure. An example is given in which the side-lobe level for a six-element array is lowered by 21 dB.
