PURPOSE: A dual antenna switching device, a dual antenna switching method, and a dual antenna radio frequency contact structure are provided to minimize influences of magnetic interferences by permitting a mobile terminal to have a dual helical antenna structure. CONSTITUTION: A dual antenna switching device comprises a first helical antenna(10) and a second helical antenna(20) arranged in the folder unit of a mobile terminal such that the first and second helical antennas transmit/receive radio frequency signals; a switch unit(30) for applying a radio frequency signal to the first helical antenna, and applying a radio frequency signal to the second helical antenna in accordance with a control signal; a radio frequency unit(50) connected to the switch unit such that the radio frequency unit transmits/receives radio frequency signals; and a control unit(60) for sensing the opening/shutting operation of the folder unit of the mobile terminal, applying control signals to the switch unit, and controlling and monitoring each unit.
