Abstract

An active windshield antenna has a first conductor extending parallel to a metal frame to the vertical line of symmetry of the latter, a second conductor extending in a bending point from said first conductor along the symmetry line, an amplifier has separate transmission paths for a low frequent low medium short wave region and ultra short wave region, the transmission path of the long medium short wave region at an inlet of the low medium short wave amplifier has a high input impedance, and the input impedance of the total amplifier in the low medium short frequency region is high.
