摘要
An antenna assembly (30) comprising a whip antenna (11) and an antenna top (12) including a helical antenna (18) and mounted on a top end of the whip antenna. The antenna assembly is slidably mounted on a Cellular telephone set (20) and movable between an extended position and a retracted position. The antenna assembly is further provided with a conductor sleeve (32) connected to the helical antenna. In the retracted position, the helical antenna is brought into electrical connected to an electrical circuitry in the telephone set through the conductor sleeve. The conductor sleeve is rotatably mounted but prevented from axial movement on a dielectric joint member (31) fixed on the top end of the whip antenna, but is fixed to the antenna top so that the antenna top is rotatably mounted on the joint member. The antenna top is mounted on the joint member but freely rotated on the joint member.
