Theoretical design/synthesis of slotted waveguide arrays

A computer aided design/synthesis procedure for array antennas of the slotted waveguide type is described. It differs from earlier contributions to this topic in that it uses theoretically evaluated self-admittances, rather than measured self-admittances, for the individual broadwall slots in the array. By adopting the moment method to generate the slot self-admittances, it is shown that accuracies which are comparable with those obtained from a measurement based procedure can be achieved.
