Abstract (en)

[origin: EP0326651A2] The invention is based on the object of implementing a radio transceiver antenna for vehicles, which antenna can be produced at the lowest possible cost. The object is achieved in that the radio transceiver antenna (25) consists of a dipole (15) arranged in or on a windscreen (14) of a vehicle, the ends (17, 18) of which dipole (15) are connected to the ends (20, 21) of a bypass line (23). One end (18) of the dipole (15) forms a feed point (24) for the antenna. The dipole (15) and the bypass line (23) each have a length of lambda /2, lambda being the mean operating wavelength. The radio transceiver antenna according to the invention is advantageously suitable for radio telephones. The drawing shows the rearside of a vehicle with a rear screen carrying a dipole. <IMAGE>
