Abstract:
The invention relates to microwave technology and can be used in measuring technology and wireless communication. The technical result is a waveguide-to-microstrip transition which provides reduced signal transmission losses and increased working bandwidth together with a low wave reflection coefficient. A contacting metal layer is arranged on an upper surface of a dielectric circuit board around a micro-strip probe, without electrical contact with the micro-strip probe and a micro-strip transmission line and forming an internal area on the dielectric circuit boar being a waveguide channel area. A closed waveguide section having a slot in the area of the microstrip transmission line is arranged on the contacting metal layer. At least one metallized transition through-hole is formed along a perimeter around the area of the waveguide channel in the metal layers and in the dielectric circuit board, and at least one non-metallized through-hole is formed inside the waveguide channel area.

Claim (Index 1):
A waveguide-to-microstrip transition comprising: an input waveguide piece having a through-hole defining an open waveguide channel, a short-circuited waveguide piece having a blind cavity defining a closed waveguide channel, and a dielectric board placed between the waveguides pieces; wherein a microstrip transmission line, a microstrip probe formed as an extension of the microstrip transmission line, and a contact metal layer are located on a top surface of the dielectric board, wherein the contact metal layer surrounds the microstrip probe with no electrical connection to the microstrip probe and the microstrip transmission line and forms an internal area on the dielectric board, the internal area being a waveguide channel area; wherein the short-circuited waveguide piece is located on the contact metal layer and has a recess in the area of the microstrip transmission line, wherein a ground metal plane surrounding the waveguide channel area is located on a bottom surface of the dielectric board, the input waveguide piece being mounted on the ground metal plane, wherein at least one metallized transition through-hole is provided along the circumference around the waveguide channel area in the metal layers and in the dielectric board, and wherein at least one non-metallized through-hole is provided within the waveguide channel area on the dielectric board.
