Claims

[Scope of utility model registration request]

Consists of a plurality of rectangular waveguides that share a power feeding opening or probe on the wide tube wall and are stacked in the direction of the short tube wall, with each waveguide having one input aperture or probe and multiple output apertures or probes. A distributor with a probe is configured, and each radiation waveguide of the waveguide slot array antenna is in phase and in phase by multistage distribution.
A power feeding circuit for a waveguide slot array antenna characterized by reverse phase or phase feeding.
