摘要: An electronic device including a shielding structure is provided. The electronic device includes a housing, a first board disposed in an inner space of the housing and including a first electrical element and a first ground layer, a second board disposed in the inner space to be spaced apart from the first board and including a second electrical element, and an interposer disposed between the first board and the second board so as to electrically connect the first board and the second board to each other. The second board includes a first surface facing the first board, a second surface facing away from the first surface, insulating layers disposed between the first surface and the second surface, first slits formed at a predetermined interval in a first conductive area disposed in a first insulating layer among the insulating layers, and second slits formed at a predetermined interval in a second conductive area disposed in a second insulating layer between the first insulating layer and the second surface. The first slits are disposed at a position where the plurality of first slits do not overlap the plurality of second slits in case the second board is viewed from above.

摘要: An electronic device including an antenna is provided. The electronic device includes a housing including a first housing structure having a first side member, a second housing structure having a second side member, and a hinge structure connecting the first housing structure and the second housing structure to each other, and a transceiver electrically connected with the first side member and the second side member. The first side member includes a first conductive member, a second conducive member spaced apart from the first conductive member, and a first nonconductive member disposed between the first conductive member and the second conductive member, as a first antenna group, and a third conductive member disposed at an edge adjacent to the hinge structure of edges of the first side member to correspond to the first conductive member, a fourth conductive member facing the second conductive member and spaced apart from the third conductive member, and a second nonconductive member disposed between the third conductive member and the fourth conductive member as a second antenna group.
