ANTENNA DEVICE, MANHOLE COVER EQUIPPED WITH ANTENNA DEVICE, AND POWER DISTRIBUTION PANEL EQUIPPED WITH SAME
An object of the present invention is to improve an antenna for IoT services intended for things that constitute an internal space. There is provided an antenna device including an antenna and a dielectric body. In an internal space which is constituted by plural faces including a first face which is an electrically conductive body, the antenna device is adapted to have a shape to be fit inside a hole in the first face. The antenna device is installed, not protruding from the hole to an outer space. The antenna and the dielectric body are placed in series between the internal space and the outer space.
