Abstract: An electronic device with an antenna is provided. The electronic device includes: a wireless communication circuit disposed inside the electronic device, a support including a first support disposed on at least a portion of a side surface of the electronic device and a second support forming a space for mounting electronic parts of the electronic device, a metal flange located on a protrusion of the first support and electrically connected to the wireless communication circuit, a slit formed between a portion of the first support and a portion of the second support, and a metal plate connected to the second support to form a cavity around the metal flange.

Abstract: Provided is an electronic device including an antenna module. The electronic device may include: a housing constituting an external appearance of the electronic device, a support member including a first bridge, a printed circuit board coupled to one surface of the support member, a first antenna constituting a first part of the housing and connected to the support member through the first bridge, a second antenna constituting a second part of the housing, a cut-off portion separating the first antenna and the second antenna, and a first connection member and a second connection member coupled to the first bridge. The first connection member may be connected to a ground of the printed circuit board through a first capacitor and may be disposed closer to the cut-off portion than the second connection member connected to the ground of the printed circuit board through a second capacitor. Other embodiments are also possible.
