Abstract: A communication device includes a dielectric substrate, an antenna layer, a metamaterial layer, a first absorber element, a second absorber element, and a third absorber element. The dielectric substrate has a first surface and a second surface which are opposite to each other. The antenna layer is disposed on the first surface of the dielectric substrate. The metamaterial layer is adjacent to the antenna layer. The antenna layer and the metamaterial layer are both positioned between the first absorber element and the second absorber element. The third absorber element is disposed on the second surface of the dielectric substrate.
