Abstract
An antenna device has a feed line including a triplate line. Each triplate line has a central conductor and two ground plates sandwiching the central conductor via an air layer. At least a part of the triplate line is configured such that the two ground plates sandwich a center substrate including a wiring pattern as the central conductor provided on a dielectric substrate via the air layer.

An antenna device, comprising:
- a feed line comprising a triplate line, the triplate line comprising a central conductor and two ground plates sandwiching the central conductor via an air layer;
- wherein at least a part of the triplate line is configured such that the two ground plates sandwich a center substrate comprising a wiring pattern as the central conductor provided on a dielectric substrate via the air layer,
- wherein the triplate line comprises a first triplate line and a second triplate line connected to be intersected with the first triplate line,
- wherein a feed signal fed from outside is transmitted from the second triplate line to an antenna element via the first triplate line,
- wherein at least a part of the first triplate line is configured such that the two ground plates sandwich the center substrate on the dielectric substrate via the air layer, and
- wherein the second triplate line comprises two ground plates and a central conductor plate comprising a metal plate.
