摘要：A wideband transition of the present invention between a planar transmission line and a waveguide comprises a substrate, a segment of the planar transmission line, a conductive patch, an adjusting conductor plate and a section of the waveguide. The segment is arranged in a top conductor layer of the substrate. The conductive patch is arranged in the top conductor layer and connected to one end of the segment. The adjusting conductor plate is arranged in the top conductor layer or another conductor layer of the substrate next to the top conductor layer and isolated from any other conductor. The section is disposed above the conductive patch and connected to a conductor plane at the top conductor layer. Another end of the segment is a first terminal of the wideband transition. Another end of the section is a second terminal of the wideband transition.

主权项：1. A wideband transition between a planar transmission line and a waveguide, comprising: a substrate including a plurality of conductor planes which are respectively arranged in a plurality of conductor layers, stacked from top to bottom and isolated from each other by an substrate filling material; a segment of said planar transmission line arranged in a top conductor layer of said substrate; a conductive patch arranged in said top conductor layer and connected to one end of said segment of said planar transmission line; an isolating slit disposed between said conductive patch and a conductor plane at said top conductor layer; an adjusting conductor plate arranged in said top conductor layer or another conductor layer of said substrate next to said top conductor layer and isolated from any other conductor; a plurality of ground vias arranged through said substrate from said top conductor layer to a bottom conductor layer, connected to each of said plurality of conductor planes and disposed around said conductor patch and said isolating slit; a section of said waveguide disposed above said conductive patch and connected to said conductor plane at said top conductor layer; and an opening arranged in one end of said section of said waveguide to isolate said segment of said planar transition line from said waveguide, wherein another end of said segment of said planar transition line is a first terminal of said wideband transition, and wherein another end of said section of said waveguide is a second terminal of said wideband transition.
