ELECTRONIC DEVICE COMPRISING ANTENNA

According to an exemplary embodiment of the present document, an electronic device may comprise a housing, an antenna structure, and a conductive support member. The housing may provide the exterior of the electronic device. The antenna structure may include a printed circuit board including a first side and a second side facing the opposite direction to the first side. The antenna structure may include at least one antenna element located on the first side or located inside the printed circuit board, closer to the first side than to the second side. The antenna structure may be located on the conductive support member. The conductive support member may include a first portion and a second portion. The first portion may be coupled with the antenna structure. The first portion may be coupled with the housing or a support structure located in the inner space of the housing. The second portion may extend from the first portion. When viewed from above the first side, the second portion may overlap the first side and may be spaced apart from the first side.
