Abstract: An antenna device according to an embodiment includes a dielectric layer, an antenna unit disposed on a top surface of the dielectric layer and including a radiator, and a dummy mesh pattern disposed around the antenna unit and spaced apart from the antenna unit. The dummy mesh pattern includes conductive lines and segmented regions at which the conductive lines are cut. The segmented regions formed in three parallel conductive lines neighboring each other among the conductive lines are not disposed together on an imaginary straight line extending perpendicularly to an extending direction of the conductive lines. A visual recognition of the antenna unit is prevented.
