  • Patent number: 10027015
    Abstract: According to various embodiments of the present disclosure, an antenna device may include: a base substrate; a mesh grid formed by transparent electrodes on at least one surface of the base substrate; and a power feeding port connected to the mesh grid to provide a power feeding signal. At least a part of the mesh grid may form a radiation element with at least one of the power feeding signal indicative of direct feeding, and the power feeding signal indicative of coupled feeding indirectly. Since the radiation element may be configured by forming the mesh grid using a transparent conductive material, the antenna device may be easily concealed. Even if the antenna device is attached to, for example, a window glass of a vehicle or a window of a building, the antenna device may contribute to the removal of a shadow region while sufficiently securing the visibility of the glass.

  • Patent number: 9705075
    Abstract: The present invention relates to a cobalt (Co) and platinum (Pt)-based multilayer thin film having a novel structure and perpendicular magnetic anisotropy, and to a fabrication method thereof. More specifically, the invention relates to a cobalt and platinum-based multilayer thin film having perpendicular magnetic anisotropy (PMA), which includes thin cobalt layers and thin platinum layers alternately deposited over a substrate, and has an inverted structure in which a thickness of the thin cobalt layers is greater than that of the thin platinum layers, and to a fabrication method thereof. The cobalt and platinum-based multilayer thin film has a new structure in which the thickness of a magnetic thin layer is greater than that of a non-magnetic thin layer. The multilayer thin film may be easily applied as a free layer and a pinned layer in a magnetic tunnel junction by controlling the perpendicular magnetic anisotropy energy depending on the thickness ratio of the layers.
