Claim:
1. A method of manufacturing a waveguide antenna comprising: providing a first metal layer including one or more waveguide channels formed into the first metal layer, wherein the first metal layer is a sheet of metal having a predefined thickness; selecting, on the first metal layer, at least one coupling surface proximate to at least edges of the one or more waveguide channels; removing an oxidation layer from a second metal layer and from a third metal layer; providing a reactive metal foil between a first surface of the first metal layer and a surface of the second metal layer, and between a second surface of the first metal layer and a surface of the third metal layer, the second surface of the first metal layer being opposite the first surface, wherein the reactive metal foil is provided to the selected at least one coupling surface; providing a fusible metal material between the first surface of the first metal layer and the surface of the second metal layer, and between the second surface of the first metal layer and the surface of the third metal layer, wherein the fusible metal material is provided to the selected at least one coupling surface; and coupling the first surface of the first metal layer to the surface of the second metal layer and coupling the second surface of the first metal layer to the surface of the third metal layer, wherein the couplings comprise:
