A dual band antenna module and an electronic device including the same are provided to transmit/receive an electromagnetic wave corresponding to different two frequency bands by using one antenna. A dual band antenna module(100) includes an antenna(101), an antenna extending block(102), and an impedance matching block(103). The antenna is matched with a first frequency. The antenna extending block is connected to the antenna in order to be matched with a second frequency lower than the first frequency in case an external signal is inputted to a terminal(SIG). The impedance matching block transmits a receiving signal of the antenna to an external device in case the external signal is not inputted to the terminal. The extending block and the impedance matching block are parallel connected in order to form a control block(104). The control block includes a first node(N1) and a second node(N2). The first node is connected to the antenna. |
