Electronic device including antenna

An electronic device comprising:

• a housing including a first side surface and a second side surface;
• a first conductive portion disposed between at least a first segmenting portion and a second segmenting portion formed in the first side surface, and including a first feeding point;
• a second conductive portion disposed between at least a third segmenting portion and a fourth segmenting portion formed in the second side surface, and including a second feeding point;
• a printed circuit board disposed at least partially inside the housing and including a ground;
• a first electronic component disposed adjacent to the first conductive portion;
• an antenna module, comprising at least one antenna, disposed adjacent to the second conductive portion;
• a first conductive connection member electrically connected to the first electronic component;
• a second conductive connection member electrically connected to the antenna module;
• a first wireless communication circuit electrically connected to the first feeding point;
• a second wireless communication circuit electrically connected to the second feeding point;
• a processor electrically connected to the first wireless communication circuit and the second wireless communication circuit;
• and
• a matching circuit electrically connected to the first conductive connection member and the ground and/or to the second conductive connection member and the ground, and configured to electrically connect and/or disconnect the first conductive connection member and the ground and/or the second conductive connection member and the ground under control of the processor.
