Description
Technical field
This utility model relates to antenna for mobile phone field, is specifically related to a kind of based on PIFA structure multi-band mobile phone antenna.
Background technology
With the development of communication technology, the development of especially 4G communication technology, the frequency range being applied to mobile communication gradually increases.Therefore, mobile phone does not require nothing more than high-quality compatibility, requires to be operated on multiband simultaneously.The high speed development of smart mobile phone makes the variation of cell-phone function by required by client, and the realization of New function will add new functional device, and it will be less that such antenna may utilize region.Therefore, antenna for mobile phone to be not only operated in multiple frequency range, has less size concurrently simultaneously.
Many scholars have done numerous studies on built-in mobile phone antenna multiband and miniaturization.Antenna for mobile phone design mainly has two kinds of structures: the first is monopole structure (monopole)；The second is plane inverse-F structure (PIFA).Monopole antenna has the special feature that it is omnidirectional radiation and on-dispersive characteristic, and the advantage such as its structure is relatively easy, advantage of lower cost.But its significant drawback is antenna to be affected relatively greatly by head and hands, and needs match circuit to realize low frequency bandwidth expansion.In the case of ensureing medium level, PIFA antenna can effectively solve the deficiency of monopole antenna, and therefore, this type of antenna obtains the widely studied of Chinese scholars.PIFA Antenna Design mainly has following two method: the first is meander technology.It is exactly to slot to realize multiple transmission path in radiation patch, the corresponding variant resonant frequency quarter-wave of variant path-length, realize different frequency ranges with this；The second is frequency multiplexing technique.Utilize single detail resonant element, utilize second harmonic as second frequency range, realize double frequency with this.Three frequencies and above multifrequency are realized, the main extension using parasitic patch unit to realize high frequency bandwidth.
Utility model content
For problem above, this utility model provides a kind of based on PIFA structure multi-band mobile phone antenna, multiple frequency range is realized by fluting and increase parasitic patch, broadening high frequency band is carried out by the coupling of parasitic patch and main antenna, to reach the requirement of 4G communication, the realization of coupled modes simultaneously will effectively reduce the size of antenna, have small size, easily process the features such as easy and integrated, can effectively solve the problem in technical background.
To achieve these goals, the technical solution adopted in the utility model is as follows: a kind of based on PIFA structure multi-band mobile phone antenna, including antenna radiation unit, sprinter's line, internal fasciole and earth point, described sprinter's line surrounds into a rectangle with opening, described opening is positioned at sprinter's line and earth point, and described antenna radiation unit is located at rectangular internal, and is connected with internal fasciole, described internal fasciole is connected with earth point, is provided with feeder panel between described earth point and sprinter's line.
Further, described feeder panel is formed by stacking by some matrix pasters.
Further, the distance between described sprinter's line and earth point is 1-2mm.
Further, the distance between described antenna radiation unit and sprinter's line is 0.4-0.6mm.
The beneficial effects of the utility model:
This utility model realizes multiple frequency range by fluting and increase parasitic patch, carrying out broadening high frequency band by the coupling of parasitic patch and main antenna, to reach the requirement of 4G communication, the realization of coupled modes simultaneously will effectively reduce the size of antenna, there is small size, easily process the features such as easy and integrated.
