An antenna device includes an antenna element including a dielectric substrate including a first surface and a second surface surfaces, a built-in feed line formed on the first surface, and a radiating element formed on the second surface and along the built-in feed line, a triplate line including a first outer conductor and a second outer conductor parallel to each other, and a central conductor arranged therebetween, a connecting portion at one end of the dielectric substrate to electrically connect the built-in feed line to the central conductor, a first hole and a second hole formed in the first outer conductor and in communication with each other. The first hole includes an opposite surface to the built-in feed line on the connecting portion with a specified space therebetween. The connecting portion is inserted in the second hole. The second hole includes an opposite regulating surface to the first surface of the connecting portion of the dielectric substrate. |
