An Optimization Procedure for Including the Higher Order Mode Coupling Between Coupling Slots in the Design of a Planar Slot Array

A simple iterative procedure to account for higher order mode coupling between adjacent coupling slots of a planar slot array is presented. The method converges rapidly and is easy to implement in conjunction with Elliott's design technique for planar arrays. The procedure is illustrated with an example and validated by a full-wave moment method analysis.
