Heatable window with high-pass frequency selective surface

An electrically conductive coating of an automotive heatable windshield having a frequency selective surface area that facilitates the transmission of radio frequency signals. The FSS area may be a high-pass filter such that RF signals at any polarization can pass through the glazing over a wide fre...

Beschreibung
Zusammenfassung:	An electrically conductive coating of an automotive heatable windshield having a frequency selective surface area that facilitates the transmission of radio frequency signals. The FSS area may be a high-pass filter such that RF signals at any polarization can pass through the glazing over a wide frequency band. The FSS area is defined by a pattern in the conductive coating such that, when the conductive coating is used to heat the windshield, electrical current flows through the FSS area to mitigate hot and cold spots.
