Abstract

A waveguide switch having a stator and an electrically conducting movable element, the stator having waveguide paths between waveguide terminal pairs, each path being switchable to conducting or nonconducting with the help of the movable element for high-frequency waves. To permit lower requirements regarding manufacturing tolerances, the movable element is designed as a septum in a gap in the stator and extends in the waveguide path, which is switched to nonconducting, in parallel to its E plane. This divides the waveguide path into two partial waveguides, which run in parallel with one another and, in comparison with the switched-to-conducting state of the waveguide path, have smaller cut-off wavelengths.
