Description
Technical field
The present invention relates to the antenna for mobile phone field, particularly a kind of installation method of unipole antenna of mobile phone.
Background technology
The topmost function of antenna is to change two kinds of electromagnetic wave energies in the different propagation mediums.In the process of power conversion, the discontinuous interface between transceiver and antenna and the Antennas And Propagation medium can appear.In wireless telecommunication system, antenna must be done suitable design according to the characteristic of these two interfaces, so that form a continuous energy transmission path between transceiver, antenna and the propagation medium.
In the mobile communication mobile phone field, its general external requirement to antenna is: antenna size is little, and is in light weight, and section is low, easy to carry, and mechanical strength is good; Its general requirement on electric performance to antenna is: horizontal plane requires that the omnidirectional radiation direction is arranged, bandwidth, and the efficient height, gain is high, is subjected to surrounding environment influence little, and is little to the human body radiation injury.
Under above trend, for antenna for mobile phone, particularly most widely used unipole antenna of mobile phone, therefore the demand that environment that common mobile phone machine plate design and installation provide for antenna and size have been difficult to satisfy its performance must introduce the performance that some new ideas and new debugging and optimization method guarantee antenna in design and installation.
Summary of the invention
The installation method that the purpose of this invention is to provide a kind of unipole antenna of mobile phone is to guarantee the performance requirement of unipole antenna of mobile phone.
The invention provides a kind of installation method of unipole antenna of mobile phone, described unipole antenna is unsettled to be installed on described cell phone mainboard, make the ground level of described unipole antenna and described cell phone mainboard keep at least the first preset distance in the horizontal direction, make the ground level of described unipole antenna and described cell phone mainboard keep at least the second preset distance in vertical direction.
Described first preset distance is 3mm, and described second preset distance is 5mm.
The width of described unipole antenna is more than the 15mm.
Described method also comprises and keeps the distance of 3mm at least between the metallic object that makes on described unipole antenna and the described cell phone mainboard, and makes the battery of described unipole antenna and described mobile phone keep the distance of 5mm at least.
Described method comprises that further the electric conductor that makes described unipole antenna and described mobile phone keeps predetermined distance.
The length range of described cell phone mainboard is 95-110mm.
Adopt the installation method of a kind of unipole antenna of mobile phone of the present invention, optimize aspect these three of space, unipole antenna space surrounding environment and cell phone mainboard length that it is installed at cell phone mainboard unipole antenna respectively are main, keep predetermined distance to reduce interference by the ground level that makes unipole antenna and cell phone mainboard, by the gain that the optimization to unipole antenna space surrounding environment improves described unipole antenna, improve the electrical property of described unipole antenna by the length range of limiting handset mainboard.
Description of drawings
Fig. 1 is the installation site schematic diagram of unipole antenna and cell phone mainboard among the present invention.
Embodiment
Further specify technical scheme of the present invention below in conjunction with drawings and Examples.
Built-in MONOPOLE antenna (unipole antenna) volume is less, is fit to the design of ultra thin handset.
During concrete the installation, following optimized Measures are arranged:
1, to the optimization of unipole antenna at the cell phone mainboard installing space:
A, with reference to Fig. 1, Fig. 1 is installation site signal Figure 100 of unipole antenna and cell phone mainboard among the present invention, MONOPOLE antenna 120 needs unsettled, and the ground level of mainboard 110 can not be arranged in the planar structure.In the horizontal direction, the antenna 120 general and mainboard 110 ground levels maintenance at least the first preset distance 3mm, in vertical direction, the antenna 120 general and mainboard 110 ground levels maintenance at least the second preset distance 5mm.
The width of B, antenna 120 should be not less than 15mm.
C, when being installed in unipole antenna 120 on the slide phone, generally it is arranged at mobile phone header board upper end or plate lower end, back.
2, to the optimization of antenna 120 space surrounding environment:
A, make and keep the distance of 3mm at least between the metallic object on described unipole antenna 120 and the described cell phone mainboard 110.Specifically, big metal object such as motor, loud speaker, receiver can not be arranged around the built-in aerial 120 in the 3mm.If loud speaker or receiver must enter above-mentioned zone, show according to repeatedly experiment, the magnetosonic device is in the empty regions of unipole antenna 120, and the vertical range that zooms out device and antenna 120 at the mobile phone thickness direction does not have tangible benefit and increased mobile phone thickness; But and along the bigger effect of cell phone mainboard 110 length direction moving device, experiment shows that the distance of 2mm is enough to increase the gain of 1dBi.
B, the distance that the described unipole antenna 120 and the electric conductor maintenance of described mobile phone are scheduled to.Specifically, near the structural member (face) the built-in aerial 120 does not spray conductive materials such as conductive paint, does not do electroplating technology near antenna 120 zones and avoids designing Metal decorative part etc.Described predetermined distance need be determined according to experiment.
C, built-in aerial 120 positive upper and lowers can not have and FPC (Flexible Printed Circuit) intersection, and mutually more than the Edge Distance 3mm.
D, built-in aerial 120 should be more than 5mm with the spacing of battery of mobile phone.
3, to the optimization of cell phone mainboard 110 length:
The length of cell phone mainboard 110 (intactly length) has significant effects to the performance of MONOPOLE antenna 120, GSM900 low-frequency range particularly, from test result, the length of the plate rolls PCB that optimizes should be between 95-110mm this scope, following table is the test comparison to antenna 120 efficient under different mainboard 110 length:
| Antenna Mhz | The 102mm plate is long | The 96mm plate is long | The 88mm plate is long |
| ??880 | ??49.6265 | ??48.563 | ??42.6192 |
