an antenna assembly for reducing the receiving space in a portable phone which employs the antenna assembly and for enhancing the bandwidth and radiation efficiency when the antenna assembly is in a retracted position . the antenna assembly includes a helical antenna and a whip antenna . the helical antenna is powered by capacitive coupling between a conductive layer therein and a feed conductor electrically connected to a signal processing circuit in the portable phone . also , the whip antenna consists of two stages in a vertical direction in a manner that one of the stages can be retracted into the other one . the helical antenna includes a conducting layer disposed beneath the helical element ; the feed conductor electrically connected to the signal processing circuit at least when said antenna assembly is retracted into the portable phone ; and an insulating layer disposed between the conducting layer and the feed conductor . the whip antenna includes a spring attached to the antenna rod ; a tube having a cylindrical shape capable of receiving at least lower half of the antenna rod ; and a stopper attached to the bottom end of the tube and contacting the antenna rod selectively . the tube has a sill at the top end thereof for holding and preventing the spring attached to the antenna rod from slipping out of the tube
