Embodiment
See also Fig. 1 and Fig. 2, the present invention's better embodiment provides a kind of antenna structure 100, and it is applied in the radio communication devices such as mobile phone.
This antenna structure 100 comprises a circuit board 10, an antenna 20, a connection piece 30, a cover plate 40, a slide plate 50 and a Department of Radiation 60.
Offer a breach 12 on this circuit board 10, and form a side 14 in these breach 12 places.One load point (not shown) and an earth point (not shown) are set on this side 14, this load point is used to the antenna structure 100 feed-in signals of telecommunication, this earth point is used to antenna structure 100 that ground connection is provided, by this load point and earth point, so that antenna structure 100 forms current circuit.
In the present embodiment, this antenna 20 is arranged in the breach 12 of circuit board 10, to save the space.This antenna 20 comprises a feed side 22, an earth terminal 24 and a radiant body 26 that is arranged in the same plane.This feed side 22 is electrically connected with load point, and this earth terminal 24 is electrically connected with earth point.This radiant body 26 comprises a initial segment 262, a linkage section 264 and an extension 266.This initial segment 262 is connected in earth terminal 24, this linkage section 264 is vertically connected between the initial segment 262 and the extension 266, this extension 266 extends in parallel towards the direction opposite with the bearing of trend of the initial segment 262, this feed side 22 roughly is connected in the centre position of extension 266, and with linkage section 264 almost parallels.
This connector 30 is used for being electrically connected antenna 20 and Department of Radiation 60.In the present embodiment, this connector 30 is a shell fragment, and it vertically is located at an end of extension 266 relative linkage sections 264, and extends towards cover plate 40 directions.The spacing of the length of this connector 30 and circuit board 10 and cover plate 40 is suitable.
This cover plate 40 can be the part of the body of radio communication device, and itself and circuit board 10 are oppositely arranged.This cover plate 40 comprises an outer surface 42 and an inner surface 44.Offer a fitting recess 422 on this outer surface 42, this fitting recess 422 comprises a diapire 424, offers an opening 426 on this diapire 424, and this opening 426 connects inner surface 44.
This slide plate 50 adopts plastics or other electrically non-conductive material to make, and it is mounted slidably in the fitting recess 422 of cover plate 40.In the present embodiment, the length of this slide plate 50 is less than the length of fitting recess 422, so that slide plate 50 slides along fitting recess 422 under operator's promotion.In addition, this slide plate 50 can by cooperating with the remainder of the body of radio communication device, not break away from fitting recess 422 to guarantee this slide plate 50 in sliding process.
This Department of Radiation 60 can be fixed on the surface of slide plate 50 by modes such as plating Copper Foil, fixed iron piece or attaching flexible circuit board, and exposes by the opening 426 of fitting recess 422.In the present embodiment, this Department of Radiation 60 comprises a primary radiation district 62 and a land 64.This primary radiation district 62 comprises the first extension (figure is mark not), the second extension (figure is mark not) and the 3rd extension (figure is mark not), this second extension is vertically connected between the first extension and the 3rd extension, the 3rd extension and the first extension extend in the same direction, and the length of the 3rd extension is longer than the first extension.This land 64 is connected in an end of relative the second extension of the 3rd extension, and extends a segment distance towards the direction parallel with the second extension.Be fixed in the position of slide plate 50 by adjusting Department of Radiation 60, when sliding skateboard 50, can make land 64 with connector 30 contacts or separate.When land 64 contacted with connector 30, the current path that antenna 20, connector 30, Department of Radiation 60 form became special ratios with the wavelength of gps signal, for use in the transmitting-receiving gps signal.For guaranteeing that connector 30 contacts with land 64 well, can be gold-plated on this land 64.When separated with connector 30 land 64, antenna 20 became special ratios with the current path that connector 30 forms with the wavelength of Bluetooth signal, for use in bluetooth.
Further specify the operation principle of this antenna structure 100 below in conjunction with Fig. 3 and Fig. 4:
When the user need to use the Bluetooth signal transceiving data, slidably slide plate 50 to one positions made the land 64 of Department of Radiation 60 not contact with connector 30.At this moment, antenna 20 and connector 30 common consist of one can bluetooth Bluetooth antenna.When the user need to use the gps signal transceiving data, but reverse slide slide plate 50 makes the land 64 of Department of Radiation 60 contact with connector 30.At this moment, antenna 20, connector 30 and Department of Radiation 60 common formations one can be received and dispatched the gps antenna of gps signal.As from the foregoing, this Bluetooth antenna and gps antenna are shared feed side 22 and earth terminal 24, and feed side and earth terminal need not independently be set separately, have effectively reduced the space that antenna takies radio communication device.
Be appreciated that antenna structure 100 of the present invention is not limited to switching Bluetooth signal and gps signal, also can be used for switching other wireless signal, for example the WIFI signal only needs the size of the radiant body (antenna 20 and Department of Radiation 60) of adjustment correspondence to get final product this moment.In like manner, it is described that the shape of antenna 20 and Department of Radiation 60 all is not limited to the present embodiment, becomes special ratios as long as guarantee the current path that forms with the wavelength of concrete wireless signal.
The antenna structure 100 that is appreciated that this case is not limited to two kinds of switchings between the wireless signal, also can be used for switching the wireless signal more than three kinds and three kinds, only needs corresponding getting final product at the corresponding radiant body of slide plate 50 increase respective wireless signals this moment.
