Abstract:
A waveguide array antenna, composed from a number of open waveguides lying in one plane on a radiation side, at least one two-layer structure comprising a dielectric layer and a perforated, electrically conductive layer being provided on the radiation side, wherein:a portion of the total number of the open waveguides is fed on a reverse side thereof, while the other ones are closed off, the at least one two-layer structure being integrated with the open waveguides, so that a periodically repeating electromagnetic resonance pattern is generated together in the two-layer structure and a face of the radiation side of the waveguides on which the two-layer structure has been provided, in parallel directions relative with the face, of which the energy of the resonance pattern, outputted via the perforations, forms a transmission beam.
