Abstract

A portable wireless device having a plurality of wireless sections capable of diversity operation which can reduce the size, thickness, weight and manufacturing cost by reducing the number of antennas. The portable wireless device (100) comprises first through third main antenna devices (101-103), first through third wireless sections (111-113) connected, respectively, with the first through third main antenna devices (101-103) and capable of diversity operation, a sub-antenna device (121) for diversity operation connected with any one of the first through third wireless sections (111-113) at the time of diversity operation, and a section (120) for switching connection of the sub-antenna device (121) with any one of the first through third wireless sections (111-113) at the time of diversity operation.

Dependent claims

A portable radio device comprising:

a first radio section capable of diversity operation;
a first antenna connected to the first radio section;
a second radio section capable of diversity operation;
a second antenna connected to the second radio section;
a third antenna that can be connected to the first radio section or the second radio section at a time of diversity operation;
a switching section configured to couple the third antenna to the first radio section or the second radio section based at least on an input from a control section;
and
the control section configured to detect an amount of received data of the first radio section, the control section further configured to compare the detected amount to a determined threshold and to generate the input to the switching section based at least on a comparison between the detected amount of the received data and the determined threshold.
