ELECTRONIC DEVICE COMPRISING ANTENNA

An electronic device, according to an illustrative embodiment of the present document, may comprise a housing, an antenna structure, and a conductive pattern. The housing may provide a front surface of the electronic device and a rear surface of the electronic device. The antenna structure may include a printed circuit board positioned within the housing and including a first side facing either the front surface or the rear surface and a second side facing the opposite direction to the first side. The printed circuit board may include a first conductive layer, a second conductive layer, and a dielectric. The first conductive layer may include a first antenna element and a second antenna element that do not overlap each other when viewed from above the first side. The second conductive layer may be positioned closer to the second side than the first conductive layer and may act as a ground plane. The dielectric may be positioned between the first conductive layer and the second conductive layer. The conductive pattern may overlap at least a portion of the second conductive layer when viewed from above the first side. The first side may be positioned between the front surface and the second side when the first side faces the rear surface. The first side may be positioned between the rear surface and the second side when the first side faces the front surface.
