Multi-band antenna architecture

A multi-band antenna architecture, provided in a matrix of a wireless communication devices, comprising:

• a first antenna, located in a left outer side area and a right outer side area of the matrix;
• a second antenna, located in an upper outer side area and a lower outer side area of the matrix;
• and
• a third antenna, located in a left inner side area and a right inner side area of the matrix;
• wherein the left outer side area, the right outer side area, the upper outer side area, the lower outer side area, the left inner side area and the right inner side area are spaced from each other, the first antenna, the second antenna and the third antenna operate at different frequency bands, and the third antenna is capable of implementing broadband and large-angle beam scanning.
