Abstract

An antenna system using a motion sensor includes an antenna having a plurality of axes within a smart device, whereby motion sensor sensing axis information is generated by movement or rotation of the plurality of axes of the antenna, and a controller for controlling the information sensed by the motion sensor and a strength of a signal of the antenna having the plurality of axes received in real time.

an antenna having a plurality of axes within a smart device, whereby motion sensor sensing axis information is generated by a movement or rotation of the plurality of axes of the antenna; and

a controller for controlling the information sensed by the motion sensor and a strength of a signal of the antenna having the plurality of axes received in real time.

2. The antenna system using a motion sensor according to claim 1, wherein the motion sensor includes an acceleration sensor, a gyro sensor or a geomagnetic sensor.

3. The antenna system using a motion sensor according to claim 1, wherein the strength of the signal of the antenna having different axes is measured using the information sensed by the motion sensor and strengths of signals of the antenna generated at first and second positions.

measuring a strength of a signal of a first-axis antenna at a first position and a strength of a signal of a second-axis antenna at the first position;

measuring a strength of a signal of the first-axis antenna at a second position and a strength of a signal of the second-axis antenna at the second position;

measuring information sensed by the motion sensor depending on a movement from the first position to the second position; and

comparing the information sensed by the motion sensor with strengths of signals of the first-axis antenna and the second-axis antenna received in real time and measured at the first and second positions.

7. The method for operating an antenna system using a motion sensor according to claim 6, wherein a strength of a signal of an antenna having different axes is measured using the information sensed by the motion sensor and the strengths of the signals of the antenna generated at the first and second positions.
