1. An antenna device comprising:
a dielectric layer; and
an antenna unit disposed on at least two of an upper surface, a side surface and a lower surface of the dielectric layer to have a bent structure,
wherein the antenna unit comprises a radiator, a transmission line branched from and integrally connected to the radiator, and a signal pad directly connected to an end portion of the transmission line,
wherein the dielectric layer is formed by folding a preliminary dielectric layer in a planar state which comprises a first region, a second region and a third region, and the second region is folded so that the first region and the third region face each other, and
a surface of the second region of the preliminary dielectric layer corresponds to the side surface of the dielectric layer.
