摘要： An antenna for mounting on a vehicle which restrains damping of a signal voltage by reducing a stray capacitance of a signal path and has an improved antenna characteristic and a short physical length, and an antenna element which is suitable for an antenna for mounting on a vehicle and is flexible by using a helical coil of a large winding diameter are provided. In the antenna for mounting on a vehicle, with respect to a band signal having a short wavelength of a plurality of band signals to be transmitted/received, an antenna element is caused to resonate with a physical length shorter than ¼ of the wavelength of the band signal. A linear line portion is provided at the proximal end, and the antenna element is provided at a predetermined distance from vehicle body and a conductive member of the same electric potential as the vehicle body. The stray capacitance between the proximal end portion of the antenna element and the vehicle body is small, and a signal voltage is outputted without being damped. The antenna element is formed by burying a helical coil coaxially into a flexible insulating resin pipe. The pitch of the helical coil is not shifted even when it is bent repeatedly. Also, no sink mark is generated in the insulating resin pipe.

摘要： A motor-driven antenna device in which an antenna element (10) has a short protruding length so that the outer dimension of the entire device is reduced, and in which damping of an AM-band signal by a signal path is restrained with a small stray capacitance. A rack cord (12) to be meshed with a pinion gear (24) is connected to a proximal portion of the antenna element (10) made of a helical coil over its entire length, and the antenna element (10) is caused to protrude and move to be housed by rotational driving of a motor drive section. The rack cord (12), the motor drive section and the pinion gear (24) are housed in a case (14), and a guide (26) to which the rack cord (12) is abutted and moves while bending is provided in the case (14). Thus, the rack cord (12) is abutted and moves to the guide (26) by the movement of the antenna element (10). In a protruding state, a linear conductor (30) is extended from the proximal end of the antenna element (10) to penetrate an earth conductive fitting (16) and electrically connected with a connection conductive fitting (32) at a position not in contact with the earth conductive fitting (16). A feeder conductive fitting (34) elastically contacts and is electrically connected with the linear conductor (30).
