An antenna module comprises: a first radiation patch having a first opening; a second radiation patch spaced apart above the first radiation patch and smaller than the first radiation patch and having a second opening; a coupling patch spaced apart above the second radiation patch and smaller than the second radiation patch; and an electricity feeding path penetrating through the first opening and the second opening so as to be connected to the coupling patch, wherein the center of the first opening and the center of the second opening are displaced laterally. As one antenna module can operate in different frequency bands, the number of antennas can be reduced.
