Abstract
Proposed is a multi-band antenna module in which antennas having different polarization characteristics are coupled so as to prevent deterioration in isolation caused by interference between the antennas. The proposed multi-band antenna module comprises a circuit board. On the top surface of the circuit board, a first upper clearance area, a second upper clearance area, an upper radiator, and an upper ground are defined so as to operate as a PIFA antenna resonating in a first frequency band. On the first upper clearance area and the second upper clearance area, a first conductor area and a second conductor area operating as a monopole antenna resonating in a second frequency band are defined.
