Energy Saving Glazing and Its Compatibility with Heating, Antenna and Wireless Communication 2019-01-1057

Conductive heat reflecting automotive windows significantly attenuate RF communication signals. A number of methods are available to maintain electromagnetic compatibility and the function of these and other devices in the passenger compartment, while accruing the heat load reduction benefits of the coating. One of the methods is to integrate antennas on to the coated glazing and have glass antenna act as a communication interface between inside and outside of the vehicle. Another approach is to design a wideband or bandpass Frequency Selective Surface (FSS) window to facilitate wireless communication while preserving the thermal performance of the window. This paper provides detailed overview on coated antennas for vehicle communications, FSS window design for wideband and bandpass applications and coated antenna combined with de-ice and de-fogger functions with some designs and testing data.
