Abstract
The utility model discloses a 3G multiband antenna for mobile equipment. The antenna comprises a radio frequency connector, a radio frequency line and a flexible print circuit plate radiator; and the flexible print circuit plate radiator and the radio frequency connector are connected by the radio frequency line. The 3G multiband antenna for mobile equipment disclosed by the utility model employs the technologies of flexible print circuit plate and microstrip impedance network to effectively reduce loss in adjusting and coupling of electronic component, and reduce height of the radiator and difficulty of anomaly of the radiator, so that the utility model gains compact overall structure and reduced volume to suit antenna environment restriction in the mobile equipment and save production cost.
Description
Technical field
The utility model relates to wireless communication technology field, particularly relates to a kind of mobile device 3G multifrequency antenna.
Background technology
At present, along with the arrival in 3G epoch, moving communicating field require general utility functions have integrated, gain is little, the miniaturization of cloth office direction and densification direction develop, this just requires antenna to have features such as multifrequency, broadband, small size.
The utility model content
Technical problem to be solved in the utility model provides a kind of mobile device 3G multifrequency antenna, its compact conformation, volume be little, save material and coverage effect good.
The utility model solves above-mentioned technical problem by following technical proposals: a kind of mobile device 3G multifrequency antenna, it is characterized in that, it comprises radio frequency connector, radio frequency line, flexible printed circuit board radiant body, connects by radio frequency line between flexible printed circuit board radiant body and the radio frequency connector.
Preferably, described radio frequency line is four layers of radio frequency line, is made of external insulation layer, grounded metal braid, insulating barrier and inner wire successively.
Positive progressive effect of the present utility model is:
(1) the utility model has effectively reduced the length of radiant body owing to adopted technology such as wide line, multifrequency, impedance matching network, makes that overall structure of the present utility model is compacter, has dwindled the volume of entire antenna, has saved production cost.
(2) simultaneously, the radio frequency line principle is applied in this mobile device 3G multifrequency antenna, has effectively expanded the beamwidth of antenna.
(3) standing-wave ratio of the present utility model at 824MHz-960MHz less than 2.5; 1710MHz-2170MHz is less than 2.0; Through the reality test, the radiation efficiency low frequency of antenna has reached more than 40%, and high frequency has reached more than 60%.
Description of drawings
Fig. 1 is the structural representation of the utility model mobile device 3G multifrequency antenna.
Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explaining the utility model, and be not used in restriction the utility model.
See also shown in Figure 1, the utility model mobile device 3G multifrequency antenna comprises radio frequency connector (RF Connector) 1, radio frequency line 2, flexible printed circuit board radiant body 3, connect by radio frequency line 2 between flexible printed circuit board radiant body 3 and the radio frequency connector 1, radio frequency connector 1 is connected with the PCB out connector of a 3G module.
By the impedance matching at the flexible printed circuit board radiant body optimum impedance coupling that little band matched line has been realized feeder line and aerial radiation oscillator is set, has optimized the standing-wave ratio performance parameter of antenna, do not utilize electronic component to mate.
In the utility model, the base material of flexible printed circuit board radiant body is the polyimides macromolecular material, and fire resistant is fit to engineering and uses, and the material of other parts of flexible printed circuit board radiant body is calendering copper, conducts electricity very well, corrosion-resistant.
Radio frequency line is four layers of radio frequency line, is made of external insulation layer, grounded metal braid, insulating barrier and inner wire successively; Little band matched line ground connection place of grounded metal braid and flexible printed circuit board radiant body welds together, and inner wire links to each other with an end at signal place, little band matched line ground connection place.
The utility model mobile device 3G multifrequency antenna is owing to adopted technology such as flexible printed circuit board radiant body and little band impedance network, effectively reduced and utilized electronic component to regulate the loss of coupling, the height of radiant body and the difficulty of the irregular processing of radiant body have been reduced, make that overall structure of the present utility model is compacter, dwindled the volume of entire antenna, to be fit to the environmental limit of mobile device inside antenna, saved production cost.
The above only is preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of within spirit of the present utility model and principle, doing, be equal to and replace and improvement etc., all should be included within the protection range of the present utility model.
