The terms “on,” “under,” “left,” and “right” are only used to indicate the relative positional relationship.

At present, the most common method for manufacturing the transparent antenna is a process that an antenna radiation element is achieved by adhering a transparent conducting thin film formed by a metal mesh process on a surface of a smooth transparent structural member by an optically clear adhesive (OCA) with an excellent transparency. As the common transparent antenna requires the adhering process of the transparent conducting thin film, implementations of the antenna are generally limited to a single layer or laminated patch form, and the form of the antenna greatly limits an operating bandwidth achievable by the antenna.
