1. An antenna system, comprising:
a single planar substrate having a front surface and a back surface;
an antenna unit attached to the front surface of the single planar substrate; and
a metal cavity adjacent to the antenna unit, the metal cavity attached to the back surface of the single planar substrate, the metal cavity comprising a first metal wall, a second metal wall and a third metal wall,
wherein the first metal wall and the second metal wall are vertically connected with the single planner substrate, and the third metal wall is parallel to the front surface,
wherein the first metal wall, the second metal wall and the third metal wall are connected in pairs to form a cover-like structure, and the cover-like structure and the single planner substrate surround a cavity space, a distance between the third metal wall and the single planner substrate is 3 to 6 mm,
wherein the metal cavity is grounded and provided with an opening connected with the outside, and
the third metal wall and the antenna unit overlap across the single planar substrate, and
the area of the single planar substrate covered by the third metal wall is larger than or equal to the area covered by the antenna unit.
