Summary :

The authors propose a waveguide π-junction with an inductive post for the element of a multiple-way power divider in a single-layered slotted waveguide array. This π-junction splits part of the power into two branch waveguides through one coupling window, and can excite densely arrayed waveguides at equal phase and amplitude. The power dividing characteristics are analyzed by Galerkin's method of moments and are confirmed experimentally. Reflection from the π-junction is suppressed to the level below 30 dB over 5.4% bandwidth by attaching an inductive post.
