An antenna apparatus can reduce gaps between laminated plates with a simple structure, and can be produced at low cost and in a small size, while ensuring reliability over a long period of time. The apparatus includes a base having a base transmission line portion, a laminated body that is composed of laminated plates placed on the base and has laminated body transmission line portions in communication with the base transmission line portion, and an antenna main body placed on the laminated body for emitting or receiving electromagnetic waves, wherein the base, the laminated plates and the antenna element plate are coupled with one another through surface to surface contact. The antenna main body has a curved plate formed of an arc-shaped elastic member protruding toward the base in a state before assembly, and the curved plate has an elastic force contributing to the coupling through surface to surface contact. |
