Title:
MICROSTRIP LINE-WAVEGUIDE CONVERTER
Document Type and Number:
WIPO Patent Application WO/2024/009339
Kind Code:
A1
Abstract:
This microstrip line-waveguide converter comprises: a waveguide; a dielectric that is disposed at the end of the waveguide and that has a notch portion formed at one end thereof in communication with the waveguide, the dielectric having a right side part and a left side part at the respective sides of the notch portion; a first ground conductor that is formed on the back surface of the dielectric and has one end electrically and mechanically connected to the inner surface of one end of the lower wall of the waveguide; a right ground conductor pad and a left ground conductor pad that are formed on the front surfaces of the right side part and left side part of the dielectric, respectively, and that are electrically connected to the first ground conductor by means of right through-conductors and left through-conductors that respectively penetrate the right side part and left side part of the dielectric from the front surface to the back surface thereof, the right and left through-conductors respectively being arranged in parallel along the right side part and the left side part; a signal conductor that is formed on the front surface of the dielectric and has one end that leads to the notch portion; and a second ground conductor that is electrically and mechanically connected to the surfaces of the right ground conductor pad, the left ground conductor pad, and the one end portion of the signal conductor, and that covers an exposed surface on the front surface side of the notch portion, the length of the second ground conductor in the axial direction of the waveguide being one-fourth the wavelength of a signal propagating through the waveguide.
