High temperature heat treatable aluminum alloys that can be used at temperatures from about \u2212420\xb0 F. Methods of reducing adhesion of these materials to such surfaces, and polymers for incorporation into such coatings are also provided. A method of bending glass sheets utilizes the device. For each row, the mating ends of the signal contacts and ground contacts are aligned in a common plane. If authentication of the user is successful, the user is enabled to perform the operation. Dielectric layers separate the radiating layers, feed line layer, and ground plane layer.
