Title:
WAVEGUIDE MICROSTRIP RADIAL PROBE CONVERSION DEVICE SUITABLE FOR W WAVE BAND
Document Type and Number:
WIPO Patent Application WO/2023/065841
Kind Code:
A1
Abstract:
The present utility model provides a waveguide microstrip radial probe conversion device suitable for a W wave band, comprising: a waveguide, which comprises a first waveguide and a second waveguide that is formed from one end of the first waveguide bending and extending, the length of the first waveguide being greater than the length of the second waveguide; and a transition structure, one end of which is provided within the second waveguide, the transition structure comprising a base substrate and a metal conduction strip that is integrated on the base substrate, the metal conduction strip comprising a microstrip line, a high inductance line that is connected to the tail end of the microstrip line, and a radial probe that is connected to the tail end of the high inductance line, and the radial probe being provided within the second waveguide, wherein the radius of the radial probe is 0.52 mm, the central angle of the radial probe is 45 degrees, and the distance between the center line of the radial probe and a short-circuit surface of the second waveguide is 0.8 mm. According to the present utility model, insertion loss may be reduced, and the effect of expanding working frequency band is achieved.
