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.

Abstract: An electronic device is disclosed. The electronic device comprises: a first plate including a first planar region facing a first direction; a second plate comprising a second planar region facing a second direction opposite to the first direction; a housing including a side member surrounding an inner space between the first plate and the second plate; a display disposed between the first plate and the second plate and viewed through the first plate; and an antenna module disposed between the display and the second plate and configured to emit electromagnetic waves to the outside of the housing. The antenna module comprises: an antenna substrate including a first surface facing the first plate, a second surface facing the second plate, and a third surface facing the inner surface of the side member; and a wireless communication circuit disposed on the first surface of the antenna substrate. The antenna substrate comprises: a first antenna adjacent to the first surface or formed on the first surface; a second antenna adjacent to the second surface or formed on the second surface; and a third antenna formed between the first antenna and the second antenna. The first antenna is formed at a first distance from the third surface, the second antenna is formed at a second distance from the third surface, and the third antenna may be formed at a third distance that is greater than the first distance and the second distance from the third surface. Various other embodiments inferred from the present specification are also possible.
