Abstract: A communication device for controlling a beam in a wireless communication system and a method therefor are provided. The communication device includes a lens including at least one layer in which unit cells are disposed, at least one processor configured to determine a beam pattern and control capacitance of each of the unit cells based on the beam pattern, and a transceiver for transmitting a signal in the determined beam pattern through the lens, which is capacitance-controlled. Each unit cell includes a first conductive member, a second conductive member overlapping at least a portion of the first conductive member, and spaced apart from the first conductive member, and a dielectric interposed between the overlapped portions of the first conductive member and the second conductive member. An overlap region of the first and second conductive members is arranged in a direction shielded from an external electromagnetic wave.
