Title:
WAVEGUIDE-TO-MICROSTRIP LINE CONVERTER, ANTENNA DEVICE, AND RADAR DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/023870
Kind Code:
A1
Abstract:
A waveguide-to-microstrip line converter according to the present invention is provided with a converter configuration unit (10) and a waveguide configuration unit (20). The converter configuration unit comprises: a dielectric (11); a straight linear signal conductor (12) formed on one surface of the dielectric (11); a first conductor layer (13) formed on one surface of the dielectric (11) and having an opening (13a) whose lengthwise direction forms a 45° angle relative to the direction of extension of the signal conductor (12); a probe (14) that is formed on one surface of the dielectric (11), extends continuously from one end of the signal conductor (12), and is located inside the opening (13a) of the first conductor layer (13); and a second conductor layer (15) that is formed on another surface of the dielectric (11) so as to oppose the first conductor layer (13) and is electrically connected to the first conductor layer (11) by a through conductor (16) which passes from one surface to the other surface. The waveguide configuration unit (20) comprises a waveguide (24) which has another end surface (24b) that opposes the opening (13a) of the first conductor layer (13) and whose lengthwise direction forms a 45° angle relative to the direction of extension of the signal conductor (12).
