Abstract

A method for controlling antennas of a mobile terminal device such as a laptop PC and a handheld PC without degrading communication speed or quality and a mobile terminal device having such control means are provided. The method comprises determining the usage of the mobile terminal device, determining an antenna to be disabled among the plurality of antennas according to the usage that is determined by the determining of usage, and disabling the antenna disabling of which is determined by determining of an antenna to be disabled, wherein the determining of usage determines usage based on the display orientation of the display unit of the mobile terminal device.

Claims

1. A method for controlling a plurality of antennas of a mobile terminal device, comprising:

determining a usage of said mobile terminal device;

determining an antenna to be disabled among said plurality of antennas according to the usage that is determined by said determining of usage; and

disabling the antenna, disabling of which is determined by said determination of an antenna to be disabled,

wherein said determining of usage determines usage based on a display orientation of a display unit of said mobile terminal device.

2. The method according to claim 1, wherein said determining of usage determines usage based on installation status that is detected by an installation status sensing unit of said mobile terminal device.

3. The method according to claim 2, wherein said mobile terminal device is a laptop PC or a handheld PC.

4. A method for controlling a plurality of antennas of a mobile terminal device, comprising:

determining a usage of said mobile terminal device;

determining an antenna to be disabled among said plurality of antennas according to the usage that is determined by said determining of usage; and

disabling the antenna, disabling of which is determined by said determining of an antenna to be disabled,

wherein said determining of usage determines usage based on an orientation of holding said mobile terminal device that is detected by a holding orientation sensing unit of said mobile terminal device.

5. A mobile terminal device having a plurality of antennas, comprising:

usage determination means for determining a usage of said mobile terminal device;

disabling determination means for determining an antenna to be disabled among said plurality of antennas according to usage that is determined by said usage determination means; and

disabling means for disabling the antenna, disabling of which is determined by said disabling determination means,

wherein said usage determination means determines usage based on a display orientation of a display unit of said mobile terminal device.

6. The mobile terminal device according to claim 5, wherein said usage determination means determines usage based on installation status that is detected by an installation status sensing unit of said mobile terminal device.

7. The mobile terminal device according to claim 6, wherein said mobile terminal device is a laptop PC or a handheld PC.

8. A mobile terminal device having a plurality of antennas, comprising:

usage determination means for determining a usage of said mobile terminal device;

disabling determination means for determining an antenna to be disabled among said plurality of antennas according to usage that is determined by said usage determination means; and

disabling means for disabling the antenna, disabling of which is determined by said disabling determination means,

wherein said usage determination means determines usage based on an orientation of holding said mobile terminal device that is detected by a holding orientation sensing unit of said mobile terminal device.
