A waveguide array antenna is composed from a number of open waveguides lying in one plane on the radiation side, of which a part is fed on the reverse side thereof, while the other ones are closed off. On the radiation side there is provided at least one two-layer structure, integrated with the open waveguides and consisting of a dielectric layer and a perforated, electrically conductive layer, in which two-layer structure, together with the layer or the face on which this two-layer structure has been provided, a periodically repeating electromagnetic resonance pattern can be generated in parallel directions relative to said face, of which the energy, outputted via the perforations, forms a transmission beam. |
