Abstract: A beamforming device in a wireless communication system is provided that includes a phased array antenna, at least one wireless communication circuit, and a lens, wherein the lens comprises a first surface oriented in a first direction, which is the direction toward the phased array antenna, and a second surface oriented in a second direction, which is the opposite direction of the first direction, and a first beam radiated from the phased array antenna is refracted after passing through a first point on the first surface, and forms a first path inside the lens and forms a second path along which the first beam is refracted at a second point on the second surface after passing through the inside of the lens along the first path, wherein the refraction angle at the second point may be formed so as to be dependent on the radiation angle of the first beam.
