An active reception antenna arranged on a non-conductive flat supporting piece (1, 2) set in a conductive body (2) of a motor vehicle, has an active four terminal network (5) having two input terminals (6a, 6b) and two output terminals (7a, 7b), an elongated antenna conductor (3a) secured on the supporting piece, an output transmission line (8) having a first section (14) of well defined layout which is connected to the output terminals (7a, 7b) and forms another antenna conductor (14) with a length (20) introducing a non-negligible however defined impedance for high frequencies between one of the output terminals (7b) and a ground contact (10), the input terminals (6a, 6b) being connected to the first mentioned elongated antenna conductor (3a) and to the other antenna conductor (14), providing an appropriate source impedance at the input of the active four terminal network, the output transmission line (8) having a second section (15) which is connected to the ground contact (10) and also to an inner connector (11a) of the first section (14) of the output transmission line (8), the inner connector (11a) being connected with another of the output terminals (7a), the one output terminal (7b) being connected to the ground contact (10).
