HOT-WIRE PATTERN STRUCTURE OF DEFOGGER FORMED ON VEHICLE GLASS AND VEHICLE GLASS ANTENNA

PROBLEM TO BE SOLVED: To provide a hot-wire pattern structure of a defogger capable of improving directional characteristics of an FM antenna in a glass antenna comprising AM and FM antennas on rear glass with the defogger formed thereon. SOLUTION: The hot-wire pattern of a defogger 10 is formed from a plurality of hot-wires 38 extending in parallel between bus bars 10a and 10b and two linear conductors 40 and 42 provided longitudinally to be disposed on one straight line in the center inside the defogger 10. The longitudinal linear conductor 40 extends over 11 hot-wire zones. The longitudinal linear conductor 42 extends over 4 hot-wire zones. The longitudinal linear conductor 40 and the longitudinal linear conductor 42 are longitudinally isolated over 2 hot-wire zones. COPYRIGHT: (C)2006,JPO&NCIPI
