Abstract: An antenna device including: an antenna module for performing communication at a predetermined communication frequency; a base having conductivity, the base including a first surface and a first recess, the first recess accommodating the antenna module and being disposed on the first surface; a radome that is a dielectric, the redome including a second surface facing the first surface of the base and a second recess which faces the first recess and is disposed on the second surface; and a waterproof structure for waterproofing the antenna module, the waterproof structure being disposed between the first surface and the second surface. The antenna module includes one or a plurality of antenna elements, and an antenna surface on which the one or plurality of antenna elements are disposed. The antenna module is accommodated in the first recess to cause the antenna surface to project from the first surface into the second recess.
