Patent 7880679 was granted and assigned to Bosch (company) on February, 2011 by the United States Patent and Trademark Office.
In a multiband antenna system for a vehicle windshield, an antenna conductor structure is provided in lateral recesses of the heating conductor field. The antenna conductor structure is non-electrically coupled to the heating conductor field with low resistance using high-frequency technology. This system ensures defrosting of the vehicle windshield in the entire wiped area without being affected by the antenna conductor structure.
