Embodiment
About this novel aforementioned and other technology contents, characteristics and effect, in the following detailed description that cooperates with reference to graphic embodiment, can clearly present.
Consulting Fig. 3 to Fig. 5, is the embodiment of this novel hand-held wireless communication apparatus 100.Hand-hold radio communication device 100 comprises a casing 1, a radio-frequency module 2 and a control module 3.Hand-hold radio communication device 100 is a panel computer in the present embodiment, but not as limit, hand-hold radio communication device 100 also can for example be an intelligent mobile phone or a GPS navigation machine etc.Certainly, the hand-hold radio communication device 100 of present embodiment also comprises the necessary element of general panel computer such as touch-control display module and battery module (not shown), yet because the emphasis that the non-this case of these elements will improve, so do not repeat them here.
Radio-frequency module 2 is arranged in the accommodation space 10, and comprises a radio circuit unit 21 and an antenna element 22 that is arranged at procapsid 11.Antenna element 22 is electrically connected on radio circuit unit 21 with received RF signal and gives off wireless signal.The outline of antenna element 22 generally is strip in the present embodiment.Radio circuit unit 21 and antenna element 22 are to illustrate with rectangular block in Fig. 3.
Condenser type closely connects inductor 33 and is arranged on the substrate 31 and an end of adjacent antennas unit 22.When back casing 12 engages with procapsid 11, condenser type closely connect inductor 33 be electrically connected on mode that sensor conductor 32(is electrically connected treat the back again row describe in detail), and can detect capacitance between sensor conductor 32 and the ground plane.Owing to can change capacitance between sensor conductor 32 and the ground plane when the sensor conductor 32 as the exterior object (not shown), condenser type closely connects inductor 33 and can detect whether exterior object is arranged near sensor conductor 32 thus, and then detects whether exterior object is arranged near antenna element 22.What deserves to be mentioned is, because sensor conductor 32 is extended to the place, the other end of adjacent antennas unit 22 by the place, a wherein end of adjacent antennas unit 22, therefore no matter exterior object is near mid portion or the both ends of antenna element 22, and condenser type closely connects inductor 33 and sensor conductor 32 all can effectively detect exterior object.Moreover, the sensor conductor 32 of present embodiment can be when the sputter anti-electromagnetic wave disturbs the copper film (not shown) of (EMI) together sputter produce, therefore need not to increase extra process cost.Moreover, use two condenser types closely to connect inductor compared to prior art, present embodiment only needs to use a condenser type closely to connect the effect that inductor 33 can reach detecting, therefore reduces production cost effectively.In addition, need a procedure that condenser type is closely connect inductor compared to prior art and be arranged at back casing 12, present embodiment then is condenser type closely to be connect inductor 33 be integrated on the substrate 31 that arranges for control circuit unit 35, can reduce by a procedure thus and further reduces production costs.What remark additionally is to be known by this novel those skilled in the art because condenser type closely connects the thin portion structure of inductor 33, so do not repeat them here.
Conducting element 34 is arranged at this condenser type and closely connects the side that inductor 33 is adjacent to back casing 12.When back casing 12 engaged with procapsid 11, condenser type closely connect inductor 33 is electrically connected on sensor conductor 32 by conducting element 34 a end.In the present embodiment, conducting element 34 is a conducting foam, but not as limit, conducting element 34 also can for example be an electroconductive elastic sheet.
What deserves to be mentioned is, when the width W of sensor conductor 32 between 12mm between the 8mm, then when exterior object near antenna element 22 to casing 1 during at a distance of 1.2 centimeters to 1.5 centimeters, condenser type closely connects inductor 33 and sensor conductor 32 can detect approaching of exterior object.In the present embodiment, the width W of sensor conductor 32 is 10mm.
In sum, this novel hand-held wireless communication apparatus 100 closely connects the area that inductor 33 collocation can increase the induction detecting by sensor conductor 32 and condenser type, and by sensor conductor 32 take the shape of the letter U and contiguous, around antenna element 22, can effectively improve the detecting effect of adjacent antennas unit 22 mid portions.Moreover because this novelly only uses a condenser type closely to connect inductor 33, and condenser type closely connects inductor 33 and is integrated in substrate 31, therefore can also effectively reduce production cost.In addition, by sensor conductor 32 can be used for film that anti-electromagnetic wave disturbs together sputter can also further reduce production costs in back casing 12, so can reach this novel purpose really.
The above person of thought, only be this novel embodiment, when the scope that can not limit this novel enforcement with this, namely the simple equivalent of doing according to this novel claim and novel description generally changes and modifies, and all still belongs in the scope that this novel patent contains.
