Adaptor for connecting a microstrip line to a waveguide using a conductive patch and a stub hole

摘要

An adaptor for connecting a microstrip line and a waveguide is disclosed that includes a microstrip line part and a waveguide part. The microstrip line part includes a microstrip port pattern and a patch pattern on an upper portion of a substrate, where the patch pattern is joined to an end portion of the microstrip port pattern. The waveguide part includes a waveguide hole, for transferring a signal provided from the patch pattern; a channel hole, which is formed in an area for joining with the microstrip line part, is formed along a first direction orthogonal to a direction of the waveguide hole in correspondence to the microstrip port pattern, and is connected with the waveguide hole; and a stub hole, which is connected with the waveguide hole and is formed in an area for joining with the microstrip line part along a second direction opposite to the first direction.
