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.

Combination antenna module and portable electronic device including same

Disclosed is an antenna module for a vehicle, which can perform wireless power transmission for a portable terminal equipped with a magnetic resonance wireless power transmission function and a portable terminal equipped with a magnetic induction wireless power transmission function in one module. The disclosed antenna module for the vehicle stacks a first antenna unit having a first antenna that is an antenna for the magnetic resonance wireless power transmission and near field communication on one surface of a base sheet, and a second antenna unit having a second antenna that is an antenna for the magnetic induction wireless power transmission on one surface of the first antenna unit; and the second antenna is partially overlapped with the first antenna.

Vehicle antenna module
