Combination antenna module and portable electronic device including same

A combo antenna module, comprising;

• an antenna unit including a circuit board and a plurality of antennas having different operating frequencies and inductances from each other;
• and
• a switching unit for connecting or disconnecting at least two of the plurality of antennas based on an operation mode of the antenna unit,
• wherein the antenna unit includes a first antenna disposed at an outermost portion of the circuit board, a second antenna disposed on a center area of the circuit board and at least one a third antenna disposed between the first antenna and the second antenna,
• wherein an operating frequency of the second antenna is lower than that of the first antenna and higher than that of the third antenna,
• wherein the first antenna includes any one of a wireless power transmission antenna of a magnetic resonance manner and a near field communication (NFC) antenna, and wherein the second antenna is a wireless power transmission antenna of a magnetic induction manner, and the third antenna is a magnetic secure transmission (MST) antenna,
• wherein a wireless performance through the first antenna is equal to or less than a reference value, the switching unit connects in parallel the first antenna with at least one of the second antenna and the third antenna.

A portable electronic device comprising;

• a combo antenna module including an antenna unit including a circuit board, a first antenna for wireless power transmission, and a second antenna for wireless power transmission of which having an inductance greater than that of the first antenna and manner is different from that of the first antenna, and a shielding unit disposed on a surface of the antenna unit to shield a magnetic field;
• a switching unit for connecting or disconnecting at least two of the plurality of antennas in parallel based on a wireless power transmission operation mode of the antenna unit;
• a plurality of wireless module coupled with the plurality of antennas, respectively;
• and a mode determination unit for determining which module of the plurality of wireless modules is operating and for controlling switching of the combo antenna module,
• wherein the first antenna is disposed at an outer portion of the circuit board, and the second antenna is disposed inside the first antenna of the circuit board,
• wherein the first antenna is a wireless power transmission antenna of a magnetic resonance manner, and wherein the second antenna is a wireless power transmission antenna of a magnetic induction manner,
• wherein when a performance of wireless power transmission through the first antenna is equal to or less than a reference value, the switching unit connects the first antenna with the second antenna in parallel.
