1. A mobile terminal cover fastened to a mobile terminal comprising:
a first antenna driven by wireless power supplied from the mobile terminal through wireless power transmission;
a second antenna driven by wireless power supplied from the first antenna to transmit a location and distance data with respect to an external measurement object within a UWB communication range to the mobile terminal;
a third antenna driven by wireless power supplied from the first antenna to get the location and distance data with respect to the external measurement object within the UWB communication range; and
a control unit for controlling the first, second and third antennas,
wherein the control unit set driving as the first antenna to receive power from the mobile terminal, set driving as the third antenna to get the data measured the location and distance with respect to an external measurement object within the UWB communication range, and set driving as the second antenna to transmit the data to the mobile terminal, and
wherein when the first antenna is set as a driving antenna, the control unit controls the first antenna to stop supplying power to the second antenna and the third antenna, and when the second antenna is set as a driving antenna, the control unit controls the first antenna to stop supplying power to the third antenna.
