Abstract

Provided are a combination antenna module and a portable electronic device including the same. There is provided a combo antenna module that includes an antenna unit including and a switching unit. The antenna unit includes a circuit board, a first wireless power transmission antenna, and a second wireless power transmission antenna of which manner is different from that of the first wireless power transmission antenna. The switching unit includes a first capacitor and a second capacitor connected in parallel to the second wireless power transmission antenna, and a switch, disposed between the first capacitor and the second capacitor, to be opened or closed based on an operation mode of the antenna unit. The second antenna and the second capacitor form a closed loop which is coupled with the first antenna when the switch is opened.
