During enforcement, said main board length down is 70mm, and said mainboard width down is 45mm; The metal copper sheet total length on mainboard prolongation ground is 30mm under the said conduct, and width is 3mm.
During enforcement, the metal copper sheet on mainboard prolongation ground and the said distance of mainboard top broadside down are 3mm under the said conduct.
During enforcement, being parallel to the metal copper sheet length that mainboard under the said conduct of said down mainboard broadside prolongs ground is 27mm.
Compared with prior art; The described clamshell phone that improves main antenna low-frequency antenna performance of the utility model; Prolong ground through on the button face-piece that is positioned at below the mainboard, increasing a following mainboard; Thereby increase the radiation ground length of main antenna low frequency GSM900 frequency range or GSM850 frequency range, can effectively improve the low-frequency antenna performance of clamshell phone.
Description of drawings
Fig. 1 is mainboard prolongs ground under the conduct on the described clamshell phone of an embodiment of the utility model metal copper sheet, main antenna, mainboard and button face-piece be near the relative position sketch map between the broadside of rotating shaft down.
Embodiment
The utility model provides a kind of clamshell phone that improves main antenna low-frequency antenna performance; Increase a following mainboard prolongation ground through going up, to increase the radiation ground length of main antenna low frequency GSM900 frequency range or GSM850 frequency range at mobile phone C shell (be the button face-piece, be positioned at mainboard top down); Can effectively improve the low-frequency antenna performance of clamshell phone; While structural design simple and stable, design cost is low, is easy to volume production and control consistency problem.
The utility model provides a kind of clamshell phone that improves main antenna low-frequency antenna performance; Comprise main antenna, descend mainboard and be positioned at the button face-piece above the mainboard said time; Said clamshell phone comprises that also mainboard prolongs ground down, and said main antenna is positioned at said mainboard bottom down;
Said mainboard down prolongs ground, is attached on the said button face-piece, and is welded in the said ground pad of mainboard down.
During enforcement, said mainboard down is made of metal with prolonging.
During enforcement, said mainboard down is the metal copper sheet with prolonging.
Based on a kind of specific embodiment; The utility model provides a kind of clamshell phone that improves main antenna low-frequency antenna performance; Comprise main antenna, descend mainboard and be positioned at the button face-piece above the mainboard said time; It is characterized in that said clamshell phone also comprises the conduct metal copper sheet on mainboard prolongation ground down, said main antenna is positioned at bottom the said mainboard down;
Mainboard prolongs the metal copper sheet on ground under the said conduct, is attached on the said button face-piece, and is welded in the said ground pad of mainboard down.
During enforcement; The metal copper sheet on mainboard prolongation ground is to adopt the design of copper sheet material directly to be attached on the broadside of said button face-piece near rotating shaft under the said conduct; The ground of while with the following mainboard of clamshell phone welds together, and it is simple to have structural design, assembles reliable and stable; The design production cost is low, is easy to advantages such as volume production and control consistency problem
As shown in Figure 1, in a specific embodiment of the described clamshell phone of the utility model, following mainboard 1 length is 70mm, and following mainboard 1 width is 45mm, and main antenna 11 designs are in this time mainboard 1 bottom; Through (being the button face-piece at mobile phone C shell; The top of mainboard under being positioned at) the metal copper sheet 13 on mainboard prolongation ground under conduct of increase; The metal copper sheet 13 on mainboard prolongation ground directly is attached on the said button face-piece under the said conduct; When design, need reserve in following mainboard relevant position and reveal zone, copper ground, the metal copper sheet 13 on mainboard prolongation ground welds together with the said ground pad 12 of mainboard 1 down under the convenient said conduct, guarantees well contact and reliability and stability.Metal copper sheet 13 total lengths on mainboard prolongation ground are about 30mm under the said conduct, and width is 3mm.The metal copper sheet 13 that mainboard prolongs ground under the said conduct is attached on the broadside 2 of said button face-piece near rotating shaft, and the said 1 top broadside distance of mainboard down of distance be 3mm, and being parallel to metal copper sheet 13 length that mainboard under the conduct of mainboard 1 broadside down prolongs ground is 27mm.
The described clamshell phone that improves main antenna low-frequency antenna performance of the utility model; Can increase the radiation ground length of main antenna low frequency GSM900 frequency range or GSM850 frequency range; Make the clamshell phone state of uncapping influenced by main board length and be reduced to minimum with the low-frequency antenna performance of closing the state of lid; The low frequency bandwidth broadens about 10MHz, and antenna radiation efficiency also obviously improves 15%, reaches 35% radiation efficiency.Antenna performance TRP and the TIS of actual this clamshell phone low-frequency range of test can improve about 2dB, have effectively improved the low-frequency antenna performance of clamshell phone, and do not influence mobile phone high frequency performance (like the DCS1800 frequency range etc.) is basic; It is simple to have structural design simultaneously, assembles reliable and stablely, and the design production cost is low, is easy to volume production and advantage such as control consistency problem etc.
In actual design, the metal copper sheet that prolongs ground as following mainboard is apart from the mainboard broadside is far away more down, and improving low-frequency effect can be good more; And as the metal copper sheet on mainboard prolongation ground should be as far as possible away from following mainboard cabling down, like this length on low frequency radiation ground being improved also can be good more, and corresponding low-frequency antenna performance also can be good more.Because for different clamshell phones; The metal copper sheet that prolongs ground as following mainboard is different apart from meeting with following mainboard broadside; And the length and the width of mainboard itself also can be different down; So to this length and width and cabling mode that prolongs the ground copper sheet also difference to some extent all; Need combine main antenna to mate according to situation such as different environment and operating handset frequency ranges and carry out the comprehensive debugging optimization work, thereby make clamshell phone reach better level in the low-frequency antenna performance of uncapping and close the state of lid with main antenna.
More than explanation is just illustrative as far as the utility model; And it is nonrestrictive; Those of ordinary skills understand; Under the situation of spirit that does not break away from accompanying claims and limited and scope, can make many modifications, variation or equivalence, but all will fall in the protection range of the utility model.
