A planar transparent antenna structure is provided. The planar transparent antenna structure includes a dielectric substrate, a radiation patch conductive layer, a parasitic patch conductive layer and a ground conductive layer. The radiation patch conductive layer is disposed on the dielectric substrate. The radiation patch conductive layer is a ring structure. The parasitic patch conductive layer is disposed on the dielectric substrate. The ground conductive layer is disposed on the dielectric substrate. The radiation patch conductive layer, the parasitic patch conductive layer and the ground conductive layer are composed of a plurality of wires interconnected and connected with each other and are light-transmissive.
