Title:
WAVEGUIDE-MICROSTRIP LINE CONVERTER AND ANTENNA DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/116416
Kind Code:
A1
Abstract:
This waveguide-microstrip line converter (10) makes it possible to convert between power propagated through a waveguide (14) and power propagated through a microstrip line. The waveguide-microstrip line converter is provided with a dielectric substrate (11), a ground conductor, and a line conductor (13). The ground conductor is provided to a first surface of the dielectric substrate and joined to an open end that is an end section of the waveguide. A slot (15) is formed in the ground conductor within an area surrounded by the opening edge (18) of the open end. The line conductor is provided to a second surface (S2) of the dielectric substrate. The line conductor comprises a first part that is a microstrip line, a second part positioned directly above the slot, and a third part used to perform impedance matching between the first part and the second part.
