MICROWAVE DIRECTIONAL COUPLER BETWEEN RECTANGULAR WAVEGUIDE AND TRIPLATE STRIP LINE

摘要

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. The width of the central conductor and values of the capacitors and inductors determines the desired coupling coefficient.
