Abstract: Provided, according to the present invention, is an electronic device equipped with a transparent antenna for 5G communication. The electronic device comprises: an antenna embedded and operating in a display, and composed of first metal mesh lines formed in a first direction; a substrate on which the antenna is disposed and which is configured to operate dielectrically with respect to the antenna; and a ground layer disposed on the bottom portion of the substrate and configured to operate on the ground with respect to the antenna. Here, an inner area of the ground layer corresponding to an area in which the antenna is disposed is composed of second metal mesh lines formed in a second direction different from the first direction, wherein a moiré effect is mitigated in the transparent antenna structure by means of the metal mesh lines overlapping in the antenna area and the ground area, thereby improving visibility.
