Synthesis of low side lobe planar arrays

A new technique for synthesis of planar rectangular arrays is presented. Using the specified design requirements for side lobe level and half-power beamwidths in the principal planes, the number of elements and element excitation currents are determined. These arrays are constructed using the patterns of uniformly excited rectangular arrays as building blocks. An important feature of these arrays is that their element currents decrease monotonically away from the array center.
