A supplementary antenna device and a method of an MS(Mobile Station) and a sensor structure are provided to receive an RF(Radio Frequency) signal at optimum level by a switched supplementary antenna when a game is played with a game convergence MS, thereby receiving a call signal of the other party even when the receive sensitivity of a main antenna is low. A main antenna(100) transmits and receives an RF signal by being integratedly comprised in a body unit of an MS. A supplementary antenna(110) transmits and receives an RF signal by being integratedly comprised in a folder unit of the MS. An RF switch unit(120) is connected to the respective antennas(100,110), and sets an RF signal transmission path. A controller(150) selects/sets paths of the supplementary antenna(110) and the main antenna(100) by a detection signal of a sensor unit(180). The sensor unit(180) detects a user's game contact state. A gaming unit(160) operates a selected game by a corresponding control signal.
