8. A rearview mirror assembly for a vehicle, the assembly comprising:
-
a mounting structure adapted for mounting to a conductive mounting button that is attached to an inside surface of a vehicle windshield; and
a tri-band antenna module mounted adjacent the conductive mounting button, the antenna module including a patch antenna and a dual-band cellular antenna, wherein the patch antenna operates at about 1.57542 GHz and the dual-band cellular antenna operates in a first range from about 824 to 894 MHz and in a second range from about 1.85 to 1.99 GHz, and wherein the dual-band cellular antenna and the patch antenna share a common ground plane. - View Dependent Claims (9, 10, 11, 12)

13. A rearview assembly for providing an image of a scene at a rear of a vehicle to a driver of the vehicle, the assembly comprising:
-
a mounting structure adapted for mounting to a mounting button that is attached to an inside surface of a vehicle windshield;
a tri-band antenna module mounted adjacent the mounting button, the antenna module including a patch antenna and a dual-band cellular antenna;
an amplifier for amplifying a signal received through the patch antenna; and
a filter coupled between the amplifier and the patch antenna, wherein the filter blocks cellular signals associated with the dual-band cellular antenna and thereby prevents the cellular signals from overloading the amplifier associated with the patch antenna. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21)
