The main board 100 may be formed to include the ground region 105 and the non-ground regions 110 and 120. Specifically, a ground region 105 is formed on a part of the main board 100, and non-ground regions 110 and 120 may be formed on the rest of the main board 100 except for the ground region 105.

The ground area 105 may be formed in a rectangle having a long side and a short side on at least a portion of the main board 100, and the ground area 105 provides a ground voltage inside the antenna module.

The power feeding parts 150 and 160 may be formed to be spaced apart from each other in the corner portion of the ground region 105.

The antennas 210 and 230 may be vertically connected to the power feeding units 150 and 160 to protrude on the ground area 105. Specifically, the antennas 210 and 230 may be formed to protrude to have a certain height and a certain area, and may be formed in various shapes such as triangles and squares.

At this time, the antennas 210 and 230 may be formed to be asymmetrical based on the power feeding units 150 and 160. 2 is a reference diagram for explaining the shape of the antennas 210 and 230 according to an embodiment of the present invention. Referring to FIG. 2, the antennas 210 and 230 having a certain area may be powered parts 150 and 160. ) May be formed asymmetrically so that the left and right areas are different. At this time, the size of the left and right areas of the antennas 210 and 230 may be formed differently according to the overall size (area and height) of the antenna module and the lowest frequency to be implemented.

For example, when the height of the antenna module is lower than 1/10 of the lowest frequency wavelength, and the frequency band to be implemented is a 0.7 GHz band, the ratio of the left and right areas of the antennas 210 and 230 may be 2.5: 1.

In order to support multiple frequency bands according to the 5G communication standard as well as the LTE communication standard, it is necessary to cover the frequency band while maintaining the isolation level of a certain level or higher. In the present embodiment, the formation location of the power supply units 150 and 160 is a ground area This effect can be achieved by forming each of the long sides of 105 to be symmetric to each other, and accordingly placing the antennas 210 and 230 along each of the long sides of the ground region 105. That is, the antennas 210 and 230 are arranged to be symmetrical to each other along each of the long sides of the ground region 105, so that the polarization between the two antennas 210 and 230 is vertically formed, thereby maintaining the isolation and maintaining the frequency band.
