Wide-band waveguide-to-microstrip transition and power divider

A waveguide-to-microstrip transition is proposed, modeled, and validated through a prototypical design. The transition is shown to possess characteristics required in many high-frequency systems, namely wide-band response, ease of construction and hermetic isolation of the two transmission media. Implementation in a waveguide-to microstrip power divider (three-port) form is detailed here, but other feasible variants are mentioned. Favorable agreement between the proposed model and measured results is observed.
