Abstract
An example method may involve forming, in a first metal layer, a first half of waveguide channels including an input waveguide channel, a plurality of wave-dividing channels, and a plurality of wave-radiating channels. The input waveguide channel may include an input port for receiving electromagnetic waves into the waveguide channels, and the first half of the plurality of wave-radiating channels may include wave-directing members configured to propagate sub-portions of waves from the first metal layer to another metal layer. The method may also involve forming, in a second metal layer, a second half of the waveguide channels. The second half of the wave-radiating channels may include pairs of output ports configured to radiate the sub-portions of waves out of the second metal layer. The method may further involve fastening the first metal layer to the second metal layer so as to substantially align the halves of the waveguide channels.
