PURPOSE: To improve the input gain over a wide frequency range from the FM radio broadcast wave to the UHF TV broadcast wave by combining a main element and an auxiliary element having specific shapes.
CONSTITUTION: Not only a defogging heater filaments 2 and bus bars 3 are formed on the vehicle inside of a glass plate 1 but also a main element 4 consisting of one horizontal filament and an auxiliary element part 5 which is extended downward from approximately a center part of the element 4 and is horizontally extended toward to one side part through a turning-back part 51 are formed in the upper blank part above the heater filaments together with a feed point 6 by screen printing and sintering a conductive paste. Thus, the FM radio broadcast wave, the TV broadcast wave in VHF band, and the UHF band are satisfactorily received.
