Window antenna and defroster with means for reducing radio interference

摘要

A vehicle window heater includes an arrangement of heating conductors provided on the window. A radio receiving antenna is located in the vicinity of the heating conductors. An interference-suppressing arrangement decreases the effect upon the antenna of interference fields emanating from the heating conductors and includes an arrangement of auxiliary conductors located in the vicinity of the heating conductors. The auxiliary conductors along their lengths are insulated from the heating conductors. Each auxiliary conductor at at least one of its ends is conductively connected to the vehicle body for high-frequency condition.
