Title:
MICROWAVE TRANSITION STRUCTURE, WAVEGUIDE AND INTEGRATED CIRCUIT
Document Type and Number:
WIPO Patent Application WO/2023/024235
Kind Code:
A1
Abstract:
Disclosed in the present invention are a microwave transition structure, a waveguide and an integrated circuit. The microwave transition structure comprises a dielectric substrate, a first fin-line transition layer and a second fin-line transition layer, wherein the first fin-line transition layer is arranged on a back side of the dielectric substrate, and has a first transition section; the second fin-line transition layer is arranged on a front side of the dielectric substrate, and has a second transition section; orthographic projections, on the dielectric substrate, of a gradient line of the first transition section and of a second transmission line of the second transition section intersect; the second fin-line transition layer is provided with a first through hole, through which a finish line of the second transition section passes; and orthographic projections, on the dielectric substrate, of a hole wall of the first through hole and the first fin-line transition layer do not coincide. By means of the technical solution of the present invention, a resonance frequency can avoid the frequency of output electromagnetic waves, thereby reducing the influence on the transition performance; and since the requirement for the precision of the first through hole is not very high, the machining difficulty of the first through hole is reduced, thereby reducing the manufacturing cost of the microwave transition structure.
