Design of unequal H-plane waveguide-power dividers for array applications

We present design data for H-plane waveguide power dividers. Such a power divider is generally used in the feed networks of waveguide antenna arrays. The power divider is a H-plane waveguide T-junction with two irises, the first to split the incoming power from port 1 to ports 2 and 3, and the second to match the input port. An integral equation moment method analysis procedure for such a structure was developed, and then used to generate some design data. Although H-plane T-junctions have been analyzed previously, no design data, to the authors´ knowledge, has yet been published for the double-iris H-plane T-junction configuration.
