According to an embodiment of the present disclosure, an antenna device implemented in a display device may comprise a dielectric layer provided in the display device, an antenna area disposed in a surface of the dielectric layer provided in a transparent area of the display device and having at least one or more antenna patterns transmitting or receiving an electromagnetic wave through a plurality of conductive grids, a power feeding area provided in at least one of the transparent area and an opaque area of the display device and having a power feeding pattern providing a signal current to the antenna pattern through the plurality of conductive grids, and a transmission line portion connecting a substrate portion provided in the display device with the power feeding pattern. Further, the antenna device according to the present disclosure may also be implemented in other various embodiments..
