PURPOSE: An antenna switch is provided to improve a reliability of the antenna switch by preventing the degradation of a frequency propagation characteristic and a frequency attenuation characteristic during transceiving a signal. CONSTITUTION: An antenna switch includes an antenna, a plurality of transceivers(100,200,300,400), and a plurality of mode selectors(500,600). The transceivers transceives a signal having a plurality of frequency bands via the antenna. The mode selectors include a resistor coupled with an external source, a diode facing an anode, and an inductor and a capacitor which are coupled between the resistor and the diode.
