Abstract
A laminated bilayer antenna windshield having an outer glass sheet laminated to an inner sheet of polyvinyl butyral carring an elongated conductive element, such as a wire, in close relation to the interfacial surface with the outer glass sheet. The bilayer antenna windshield has a higher Q-value than similar bilayer laminated antenna windshields provided with a layer of polyvinyl butyral carrying the elongated electroconductive element in spaced relation to said interfacial surface or than the Q-value of conventional trilayer windshields having two glass sheets laminated to opposite sides of a layer of polyvinyl butyral carrying the elongated electroconductive element.
