Beamforming antenna module comprising lens

A base station comprising an antenna module, the antenna module comprising:

• a plurality of antenna arrays on an antenna plane, the plurality of antenna arrays including a first antenna array and a second antenna array;
• and
• a lens including a pattern,
• wherein the first antenna array radiates a first radio wave deflected at a first predetermined angle from a vertical plane for the antenna plane in respect to a side of the vertical plane,
• wherein the second antenna array radiates a second radio wave deflected at a second predetermined angle from the vertical plane for the antenna plane in respect to another side opposite to the side of the vertical plane,
• wherein a combined radio wave is formed based on a combination of the first deflected radio wave and the second deflected radio wave,
• wherein the first predetermined angle and the second predetermined angle are determined such that a central axis of a phase distribution of the phases of the combined radio wave is aligned to a central axis of the lens,
• wherein the first predetermined angle is determined based on a distance between the lens and the antenna plane, a distance between the first antenna array and the second antenna array, and a width of the first antenna array,
• wherein the second predetermined angle is determined based on the distance between the lens and the antenna plane, the distance between the first antenna array and the second antenna array, and a width of the second antenna array, and
• wherein the pattern formed on the lens changes phases of the combined radio wave.
