COMBINATION ANTENNA MODULE AND PORTABLE ELECTRONIC DEVICE INCLUDING SAME

WIPO Patent Application WO/2017/014467

A1

Provided are a combination antenna module and a portable electronic device including same. A combination antenna module according to an embodiment of the present invention comprises: an antenna unit including a circuit board, a first antenna for wireless power transmission, and a second antenna for wireless power transmission through a technique different from the first antenna; and a switching unit provided with a first capacitor and a second capacitor connected in parallel to the second antenna, and a switch disposed between the first capacitor and the second capacitor and being opened and closed according to the operating mode of the antenna unit, wherein the second antenna and the second capacitor form a closed loop coupling with the first antenna when the switch is open. According to the present invention, because switching is implemented according to the operating mode of the antenna unit, and a closed loop is formed using an antenna in another mode, a separate resonant circuit is additionally formed to couple thereto, thus wireless power transmission can be improved, or the range of wireless communication and the efficiency or performance thereof can be increased.
