1. An antenna assembly comprising:
a first layer comprising a dielectric substrate that comprises a transparent dielectric material; and
a second layer having a metal mesh shape on a surface of the dielectric substrate,
wherein the second layer comprises:
a metal mesh radiator region having metal lines that form a mesh shape having a line-width less than or equal to a first line-width to transmit and receive a wireless signal, and an open area; and
a dummy metal mesh region having metal lines and slits that form a mesh shape having a line-width less than or equal to a second line-width,
wherein the metal mesh radiator region has a first transmissivity, and the dummy metal mesh region has a second transmissivity that is higher than the first transmissivity,
wherein the dummy metal mesh region is spaced away from an outer portion of the metal mesh radiator region,
wherein the mesh shape of the dummy metal mesh region overlaps virtual cut lines extending along a first axial direction and a second axial direction, and forms the open area,
wherein the virtual cut lines and a plurality of polygons formed by the metal lines in the mesh shape of the dummy metal mesh region are overlapped in a line-width region corresponding to an interior of the polygons,
wherein the virtual cut lines are arranged on the dummy metal mesh region to be equally spaced from each other,
wherein a boundary of a portion of the dummy metal mesh region and a boundary of the metal mesh radiator region are spaced apart by a first gap,
wherein a first region of the dummy metal mesh region that is spaced by a distance less than or equal to a second gap away from the boundary of the metal mesh radiator region forms an open dummy region in which slits by which the metal lines in the mesh shape are disconnected are present, and
wherein a second region of the dummy metal mesh region that is spaced by a distance greater than or equal to the second gap away from the boundary of the metal mesh radiator region forms a closed dummy region in which shapes of the mesh shape are connected to each other.
