Abstract
A reradiation antenna comprises, an insulation plate; a loop-shaped radiation unit formed on one surface of the insulation plate, disposed along an outer circumference of the insulation plate, and having one end and the other end disposed to be adjacent to each other; a ground connected to the end of the radiation unit; and a power supply unit connected to the other end of the radiation unit so as to supply power, and can receive a wireless signal and transmit the wireless signal to a terminal without degrading the performance of a wireless charging device.
Claims20
A reradiation antenna coupling with an antenna of a mobile terminal, the reradiation antenna comprising:
- an insulating board;
- a loop-shaped radiation unit formed along a circumference of the insulating board in one surface of the insulating board, with one end and the other end which are arranged adjacent to each other;
- a ground connected with the end of the radiation unit;
- and
- a power supply unit connected with the other end of the radiation unit and configured to supply an electric power,
- wherein upper and lower portions of the loop-shaped radiation unit are thicker than other portions of the loop-shaped radiation unit.
A wireless charging device comprising:
- a housing;
- a power transmission coil located in the housing and configured to transmit power to an external mobile terminal;
- a reradiation antenna located on the wireless transmission coil and configured to receive and re-radiate an antenna signal for the external mobile terminal;
- and
- a power supply unit configured to supply power to the power transmission coil and the reradiation antenna,
- wherein the reradiation antenna comprises:
- an insulating board;
- a loop-shaped radiation unit formed along a circumference of the insulating board in a predetermined portion of one surface of the insulating board, where the loop-shaped radiation unit is not overlapped with the power transmission coil;
- a ground connected with the end of the radiation unit;
- and
- a power supply unit connected with the other end of the radiation.
A reradiation antenna comprising:
- an insulating board;
- a loop-shaped radiation unit formed in one surface of the insulating board, with one end and the other end which are arranged adjacent to each other;
- a ground connected with the end of the radiation unit;
- and
- an electromagnetic field shut-off pattern located in a central portion of another surface of the insulating board.
