Abstract :
The authors have proposed a waveguide pi -junction with an inductive post for the element of a multiple-way power divider in a single-layer slotted waveguide array, in which a feed waveguide is placed on the same layer in the radiating waveguide. The power dividing characteristics have been analyzed by Galerkin´s method and confirmed experimentally. A -6 dB model pi -junction for the 4 GHz band was designed and fabricated. The analysis accurately predicts the power difference between two output waveguides and the reflection which is below -30 dB over a 5.4% bandwidth.<>
