Abstract
An improved analysis procedure for planar waveguide slot arrays has been devised and assessed. It takes into account the main interferences between radiating and coupling slots, and between coupling slots and T-junctions, and waveguide bends used in the array feeding network. All these effects have been modeled using in-house MoM codes, and Elliott’s slot array model has been extended to include them. The results of this improved procedure have been compared with experimental data showing a very good agreement.
