Abstract
An object of the invention is to provide a slot array antenna in which unstable factors for contact of an adjustment portion comprising a slot waveguide and a waveguide holder are removed, a number of parts is decreased to save weight, and assembly is simplified. Accordingly, this invention is to constitute a radiation portion () unitedly formed of a slot waveguide (), a flare holder (), and a supporting portion (), if necessary, further adding a screen holder () for a screen () for cross polarization suppression. Furthermore, this invention is to constitute a reinforcement feeder () unitedly formed of a feeder waveguide (), a reinforcement portion () and a reinforcement connector () in the case of an open type antenna.
