Abstract
A wireless communication apparatus for performing wireless communication using an antenna selected from a plurality of antennas. A received power detection unit detects received power received by an antenna selected from the plurality of antennas. A reflected power detection unit detects transmitted reflected power of the selected antenna. A switching unit switches an antenna used for communication to another antenna based on a variation of the received power detected by the received power detection unit and an amount of electric power of the reflected power detected by the reflected power detection unit.
Claims9
A wireless communication apparatus for performing wireless communication using an antenna selected from a plurality of antennas comprising:
- a received power detection unit which detects received power received by an antenna selected from the plurality of antennas;
- a reflected power detection unit which detects transmitted reflected power of the selected antenna;
- and
- a switching unit which switches an antenna used for communication to another antenna based on a variation of the received power detected by the received power detection unit and an amount of electric power of the reflected power detected by the reflected power detection unit.
A wireless communication apparatus for performing wireless communication using an antenna selected from a plurality of antennas comprising:
- a received power detection unit which detects received power received by an antenna selected from the plurality of antennas;
- a contact detection unit which detects contact of an object at a predetermined position from the selected antenna on a housing of the wireless communication apparatus;
- and
- a switching unit which switches an antenna used for communication to another antenna based on a variation of the received power detected by the received power detection unit and a contact detection result of the contact detection unit.
A control method for a wireless communication apparatus for performing wireless communication using an antenna selected from a plurality of antennas comprising:
- a step of switching a selected antenna to another antenna based on a variation of received power received by the selected antenna and an amount of electric power of transmitted reflected power of the selected antenna.
A control method for a wireless communication apparatus for performing wireless communication using an antenna selected from a plurality of antennas comprising:
- a step of switching an antenna used for communication to another antenna based on a variation of received power received by a selected antenna and a detection result of detecting contact of an object at a predetermined position from the selected antenna on a housing of the wireless communication apparatus.
