PURPOSE: A multiband antenna is provided to reduce size by transmitting and receiving a frequency band signal of multiband to one antenna. CONSTITUTION: Radiators(11,12) are connected to a feeding unit and transmits and receives a signal. A resonant pattern is projected from the radiators. One or more resonant cavities(30,40) are formed in the radiators. One or more resonant cavities transmit and receive a signal of frequency band which is different to the frequency band of the signal transmitted and received from the radiators. One or more clearance units(31,41) are formed by eliminating a predetermined area of the radiators. A capacitive element is formed in the clearance units.
