Following embodiment will further specify the present invention in conjunction with above-mentioned accompanying drawing.

Embodiment

See also Fig. 1 and Fig. 2, the radio communication device 100 of a preferred embodiment of the present invention comprises housing 10, first antenna 20, second antenna 30, radio-frequency (RF) switch 40 and radio circuit 50 and transducer 60.This radio communication device 100 can be portable electronic equipments such as mobile phone, PDA and IPAD.

This housing 10 comprises two ends 11 that arrange relatively and two sidewalls 12 that arrange relatively.This two sidewall 12 and these 11 vertical linking to each other of two ends.These housing 10 surfaces roughly centre position are provided with a display screen 13.This housing 10 has first grip part 14 and second grip part 15.See also Fig. 3 and Fig. 4, in this preferred embodiment, two sidewalls 12 of housing 10 form (part that is held shown in Figure 3), and this second grip part 15 is any end 11(part that is held shown in Figure 4 of housing 10).

In this preferred embodiment, when first grip part 14 of user's handling housing 10, radio communication device 100 is in first modes of emplacement, display screen 13 is in vertical state (state shown in Figure 3), when second grip part 15 of user's handling housing 10, radio communication device 100 is rotated in a clockwise direction 90 degree, is in second modes of emplacement, and display screen is in level (state shown in Figure 4).

This first antenna 20 is arranged at housing 10 1 ends 11, near the edge of housing 10 interior circuit boards (figure mark), and to should second grip part 15.This second antenna 30 is arranged at housing 10 1 sidewalls 12, near circuit board, and to should first grip part 14.When user's handling first grip part 14, but first antenna, 20 operate as normal, transmission or received RF signal, second antenna 30 then may be because user's hand blocks, and the signal radiance is not good.When user's handling second grip part 15,20 on this first antenna is blocked by user's hand, and the signal radiance is not good, but second antenna 30 operate as normal then sends or received RF signal.

See also Fig. 2, this first antenna 20 and second antenna 30 link to each other with radio circuit 50 through radio-frequency (RF) switch 40, and this transducer 60 links to each other with radio-frequency (RF) switch 40.

This radio circuit 50 is selected to receive/launch signal frequently by first antenna 20 or second antenna 30 by radio-frequency (RF) switch 40.The modes of emplacement of these transducer 60 sensing radio communication devices 100, and switch radio-frequency (RF) switch 40 according to the modes of emplacement of radio communication device 100.

In first preferred embodiment of the present invention, this transducer 60 is acceleration transducer, this acceleration transducer is arranged in this housing 10, it can respond to housing 10 motion states, and judge the modes of emplacement that radio communication device 100 is current according to its motion state, for example radio communication device 100 is turn 90 degrees by the horizontal level dextrorotation, can judge that then it is converted to second modes of emplacement by first modes of emplacement, namely is converted to position shown in Figure 3 by position shown in Figure 2.

In second preferred embodiment of the present invention, this transducer 60 is Proximity Sensor, and this Proximity Sensor is arranged in the housing 10, and the position of close first antenna 20.Whether this Proximity Sensor judges the position of radio communication devices 100 near first antenna 20 by sensing user, for example, sense user's handling second grip part 15 as this Proximity Sensor, namely near first antenna 20, can judge that this radio communication device 100 is in first modes of emplacement, on the contrary, judge that then this radio communication device 100 is in second modes of emplacement.

This acceleration transducer or Proximity Sensor are according to radio communication device 100 modes of emplacements, and control radio-frequency (RF) switch 40 selects first antenna 20 or second antenna 30 to link to each other with radio circuit 50.Particularly, when radio communication device 100 is in first modes of emplacement, then control radio-frequency (RF) switch 40 and switch to first antenna 20, it is linked to each other with radio circuit 50; When radio communication device 100 is in second modes of emplacement, then control radio-frequency (RF) switch 40 and switch to second antenna 30, it is linked to each other with radio circuit 50, thereby, make radio communication device 100 all can obtain preferable communication efficiency in first modes of emplacement and second modes of emplacement.
