  • Apparatus for microwave directional coupling between a waveguide and a stripline
    Patent number: 4433313
    Abstract: A method and apparatus for directionally coupling two technically different microwave transmission lines, one being a waveguide and the other a stripline, in which a central conductor of the stripline is plunged into waveguide through a slot in a wall of the waveguide and loaded by capacitors or inductors.
