Abstract:
A transducer connected between a wave-guide tube and a microstrip line, comprising:an insulating structure having a first major surface and a second major surface having a first area exposed to an opening of said wave-guide tube;a plurality of vertical conductive members extending in a direction of the thickness of said insulating structure in such a manner as to surround a zone over said first area; p1 an antenna probe supported by said insulating structure, having one end connected to said microstrip line, and located within said zone for relaying an electromagnetic wave between said wave-guide and said microstrip line;a conductive pattern supported by said insulating structure, having a conductive path to a source of ground voltage, and connected to the other end of said antenna probe; anda conductive cap attached to said first major surface, and defining a space over at least a second area in said zone.
