The aerial of antennas FM 1 and FM 2 comprises, in addition to the original defrosting network ( 2 ), two pairs of vertical lines ( 9,10 ) which are disposed symmetrically in relation to the median vertical longitudinal plane of the vehicle. The FM1 signal is collected at a point ( 12 ) of the aerial which makes it possible to obtain a directive signal in the direction of the length of the vehicle on a plane with zero height. The FM2 signal is collected at a point ( 13 ) which is different from the aerial, making it possible to obtain a directive signal in the direction of the width of the vehicle on a plane with zero height. The serigraphed antenna for the rear window of a salon-type car provides excellent reception for FM, AM and servitude function modes.
