Abstract

An exterior rearview mirror assembly for a vehicle includes a reflective element subassembly which includes a reflective element mounted to a backing plate and/or bezel which extends at least partially around the back surface of the reflective element. An antenna is wound or otherwise positioned around at least a portion of a perimeter or outer portion of the reflective element subassembly. The antenna may be functional to transmit or receive signals for a corresponding signal device of the vehicle, such as a radio, a passive entry system, a cellular telephone system, and/or the like. The antenna and/or a connector for connecting the antenna to a corresponding connector at the mirror assembly or vehicle or door of vehicle may be integrally molded with the backing plate or bezel to further protect the antenna and improve the assembly processes of the mirror assembly.
