Abstract :
We present a perturbation technique for improving the design parameters of a waveguide-fed planar slot array consisting of longitudinal radiating slots and centered-inclined coupling slots. Initial design is performed using the well-known Elliott technique. Subsequently a method-of-moments solution to the pertinent coupled integral equations of the aperture electric field of all slots in the array is employed to perturb the slot parameters. This process improves the slot aperture distribution and the return loss.
