Title:
WAVEGUIDE MICROSTRIP LINE CONVERTER AND ANTENNA DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/138603
Kind Code:
A1
Abstract:
This waveguide microstrip line converter (10) is provided with a waveguide (14), a dielectric substrate (11), a ground conductor having a slot (15), and a line conductor (13). The line conductor (13) has: a first section which is a microstrip line (35) having a first line width; a converting part (31) which is a second section having a second line width and located directly above the slot (15), the second line width being greater than the first line width; and a third section that extends from the second section in a first direction and bears impedance matching between the first section and the second section. One end among both ends of the third section in the first direction is connected to the second section. The first section is connected to the other end (38) among both the ends of the third section and extends in a second direction perpendicular to the first direction.
