Abstract

The present disclosure relates generally to a multi-band antenna device and an electronic device having the same. An antenna device according to embodiments may include a first antenna and a second antenna. The first antenna may include a first ground terminal, a first feed terminal, and a first radiator. The second antenna may include a second ground terminal, a second feed terminal, a second radiator, and a conductor pattern electrically connected to the second ground terminal. The conductor pattern may be formed at a position capable of causing coupling with the first radiator. Other embodiments are possible.
