Abstract:
1. A multilayer patch antenna of planar construction having a plurality of faces and/or layers arranged along an axial axis, the patch antenna comprising: an electrically conductive ground face, a conductive radiation face which is arranged at a distance above the ground face and extends substantially parallel thereto, a dielectric carrier arranged between the ground face and the radiation face, the radiation face being electrically connected to an electrically conductive supply line, a carrying means provided on the side of the radiation face that opposes the ground face, and an electrically conductive patch element provided on the side of the carrying means that opposes the radiation face and is displaced from the radiation face, the carrying means having a thickness occupying the entire spacing between the radiation face and the electrically conductive patch element when viewed in cross-section, the carrying means thickness being less than the thickness or height of the patch element, wherein the thickness or height of the patch element is more than double the thickness of the ground face and/or the thickness of the radiation face.
