Provided according to the present invention is an electronic device having an antenna. The electronic device may comprise: a transparent antenna built into a display and configured to emit a signal to the front of the display; and a transmission line for feeding the transparent antenna. The transparent antenna is configured as a rectangular patch rotated at a predetermined angle, and a portion of the left and right-side areas of the rectangular patch may be formed as vertical lines.

An antenna assembly comprises: a dielectric substrate; a first ground region disposed on one side of a feed line disposed on the dielectric substrate; a radiator region in which a first side and a second side corresponding to the opposite side of the first side form end portions of conductive patterns such that the conductive patterns having different widths are formed in a plurality of step structures; and a second ground region disposed on the other side of the feed line, wherein the first ground region may be formed to have a length greater than or equal to that of the second ground region in one axial direction. The number of steps on the second side may be greater than or equal to the number of steps on the first side.

A wireless power transmitter includes a signal generator for generating power signals, a modulator for modulating a phase of a power signal to be time reversed based on beacon signals received from the wireless power transmitter and modulating an amplitude of a power signal to be amplified, a controller for providing a phase and amplitude control algorithm to be performed by the modulator, and an antenna unit for transmitting the power signals and receiving the beacon signals. The wireless power transmitter controls the amplification of amplitudes by using the phase and amplitude control algorithm, thereby improving wireless power transmission efficiency. In addition, the wireless power transmitter includes a multiple polarization antenna to enable high-efficiency wireless power transmission, regardless of a direction of the power signals and a direction of polarization.
