Abstract

The present invention provides a transparent antenna and touch sensing device that includes an optical-grade protective cover, an antenna loop, a touch sensing layer and a transparent optical adhesive. The material of the antenna loop is a micron-level metal wire, and the visibility of the antenna loop is lower than a predetermined visibility. The transparent optical adhesive is used to adhere the optical-grade protective cover plate and the touch sensing layer, and the antenna loop is located between the optical-grade protective cover plate and the transparent optical adhesive.
