Title:
DEVICE AND METHOD FOR CONTROLLING BEAM BY USING LENS IN WIRELESS COMMUNICATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2019/199080
Kind Code:
A1
Abstract:
The disclosure relates to a pre-5th-Generation (5G) or 5G communication system for supporting higher data rates beyond 4th-Generation (4G) communication system such as long term evolution (LTE). The beamforming device in a wireless communication system may include an antenna array, a communicator configured to perform beamforming of the antenna array by applying a phase pattern for forming a plurality of beams, and a lens configured to adjust phases of respective incident signals by using the plurality of beams and emit output signals, wherein the lens includes unit cells corresponding to the phase pattern. Accordingly, the transmission device and method can reduce a distance between an antenna and a lens in a wireless communication system.
