Waveguide to stripline transition means

Claim 1

Apparatus for coupling electromagnetic energy from a rectangular waveguide to a stripline transmission line comprising a folded tee junction having an input port connected to a waveguide, a pair of parallel superimposed output ports disposed at right angles to said input port and separated by a wall between the two, the wave energy in the respective output ports being 180* out of phase with respect to each other, a stripline transmission line comprising an inner conductor sandwiched between the dielectric slabs and having an outer layer of electrical conducting material on either side of said inner conductor, means connecting said outer layers of said stripline transmission line to the wall of said tee junction, said inner conductor of the stripline transmission line lying in essentially the same plane as the wall between said parallel output ports, and a load impedance disposed on the side of said input port of the folded tee junction opposite said parallel output ports.
