1. An electronic device comprising:
at least one hinge device;
a plurality of housings that are foldably connected to each other via the at least one hinge device and configured to at least partially define a rolling space in a rolled state;
a flexible display supported by the plurality of housings and disposed to be visible from outside in the rolled state;
a cavity defined to have a predetermined spatial volume in a first housing among the plurality of housings, the cavity being sealed by the first housing and including a slit that is at least partially connected to the outside; and
a wireless communication circuit disposed in an inner space of at least one housing among the plurality of housings and electrically connected to a first point within the cavity,
wherein the wireless communication circuit is configured to form a radiation pattern through a cavity structure,
wherein the first housing is made of a conductive material, the first housing including a first surface supporting a portion of the flexible display, a second surface facing away from the first surface, and a side surface surrounding a space between the first surface and the second surface,
wherein the cavity is formed through the first surface, the second surface, and the side surface,
wherein the slit is disposed on the second surface and the side surface at a position corresponding to at least a portion of the cavity,
wherein the slit is formed in an L-shape in which a first portion of the slit extends in a first direction on the second surface and a second portion of the slit extends in a second direction perpendicular to the first direction on the side surface,
wherein the first portion of slit extending in the first direction on the second surface extends into the side surface in the first direction to connect with the second portion of the slit extending in the second direction on the side surface, and
wherein the slit changes direction from extending in the first direction to extending in the second direction on the side surface.
