Document Type and Number:

Japanese Patent JP7076347

Kind Code:

B2

Abstract:

Provided is a waveguide that has a power supply structure capable of mitigating sudden changes in impedance, and can prevent trouble during manufacturing such as dielectric substrate warping, cracking, and filling defects. This waveguide comprises: a dielectric substrate (10); a first conductor layer (11) and a second conductor layer (12) that are formed on a lower surface and an upper surface thereof; a pair of side wall parts (13) that form side walls of both sides of the waveguide; and a feed part (15) that feeds an input signal to the waveguide. The feed part is structured including a feed terminal (20) that is formed on the lower surface of the dielectric substrate and does not contact the first conductor layer, one or a plurality of first via conductors (30) that are each connected at a lower end thereof to the feed terminal, a first connection pad (21) that is connected to an upper end of each first via conductor, and a plurality of second via conductors (31) that are each connected at a lower end thereof to the first connection pad. The sum of the cross-sectional areas of the plurality of second via conductors is greater than the sum of the cross-sectional area(s) of the one or plurality of first via conductors.
