摘要： A multi-band antenna system is provided. The antenna system can be placed under and embedded within a glass exterior surface of a vehicle. Such an antenna system can include a capacitively coupled metallic element on or adjacent to the glass exterior surface, which can serve as both a parasitic element to enhance gain and as a heating element to melt snow and/or ice accumulation over the glass area that covers the antenna. In certain applications, the antenna's structure itself can be used as a heater to improve performance in adverse weather conditions while the heating elements are positioned away from the thermally sensitive electronics. The antenna system with integrated heating can include a spiral antenna.
