Vehicle-mounted double-frequency satellite navigation glass antenna

The invention discloses a vehicle-mounted double-frequency satellite navigation glass antenna which is a skylight glass antenna device applied to a vehicle. The antenna can be installed and combined with a vehicle skylight, and the defects that the design difficulty is increased when the antenna is installed in a shark fin and the antenna performance is restricted due to the fact that the antenna is greatly influenced by surrounding electric appliances when the antenna is installed in front of an instrument panel and the like are overcome. The antenna comprises a glass substrate, a signal layer, a grounding plate (1) and a dielectric substrate (7), and the signal layer and the dielectric substrate (7) are clamped in the glass substrate. The grounding plate (1) is positioned on the glass substrate surface layer; the signal layer comprises a micro-strip network (2) and an input micro-strip line (10) coupled with the micro-strip network (2). 本发明公开了车载双频卫星导航玻璃天线，为一种应用于车载的天窗玻璃天线装置；可与车辆天窗安装结合，避免发生安装在鲨鱼鳍内出现的增大设计难度以及安
