Abstract: The present invention provides a transparent antenna including a transparent dielectric substrate, an electroconductive antenna element positioned along a major surface of the substrate, an electroconductive patch capacitively or directly connected to the antenna element, and a connector secured to the patch to permit transfer of signals generated by the antenna element to an electromagnetic energy transmitting and/or receiving device. The patch, is configured to have a visibility coefficient (i.e. a ratio of the non-opaque area to the total area) between 0 and 1. In one particular embodiment of the invention, the antenna element includes one or more transparent, electroconductive coatings positioned between first and second glass plies of a windshield for a motor vehicle and the electroconductive patch is applied to an exposed major surface of the windshield such that it overlays at least a portion of the antenna element and is capacitively coupled to the antenna element.

Abstract: In bending glass sheets by the gravity sag method, the glass is supported on a rigid metal outline mold composed of one or more metal rails having a heat capacity appreciably greater than that of the glass sheet to be bent. The glass sheet portion that is in direct contact with the rail for the entire heating cycle incidental to glass sheet bending tends to break. The present invention provides a simple but effective means to reduce the incidence of glass breakage during thermal treatment incidental to bending by providing the end portions of the rail with thin sheet metal members folded thereover.
