Abstract

An electronic device includes a display having a plurality of layers; a conductive mesh pattern disposed on a first layer among the plurality of layers and formed adjacent to a first edge of the display; a feeding line connecting from the first edge to the conductive mesh pattern; and a wireless communication circuit electrically connected to the feeding line and feeding electricity to the conductive mesh pattern through the feeding line, wherein the first layer includes the conductive mesh pattern and a dummy pattern in a first area in an area surrounding the conductive mesh pattern, the first area corresponding to an area between the conductive mesh pattern and the first edge, the dummy pattern being spaced apart from the feeding line, and the first layer does not include a conductive pattern in a second area remaining after excluding the first area from the area surrounding the conductive mesh pattern.
