Abstract
An antenna structure of a mobile terminal includes a whip antenna, a helical antenna mounted to the mobile terminal and pierced with the whip antenna in a lengthwise direction thereof, a bushing for fixing the helical antenna to the mobile terminal and connecting the helical antenna or the whip antenna to a radio frequency (RF) block, a projection for stopping extension of the whip antenna, a driving motor for generating a driving force to retract/extend the whip antenna according to a specified control signal, and rollers for transmitting torque generated from the driving motor to the whip antenna to be retracted/extended. The whip antenna includes: a non-conducting upper portion disposed at a position of the helical antenna when the whip antenna is retracted; an intermediate portion including a conducting wire isolated with an insulating material of a predetermined thickness, and a conducting connection having a predetermined width to be coupled to the bushing when the whip antenna is extended; and a non-conducting lower portion having the projection at the lower end thereof, wherein the upper portion, the intermediate portion and the lower portion are equal in diameter.
