Abstract
The utility model discloses a kind of PCB antenna of high-isolation 2.4G double antenna, including pcb board, first antenna, the second antenna, resonator；The first antenna, the second antenna are set as inverted f structure, and first antenna, the second antenna are equipped with the connecting pin of feed point end and connecting PCB board；The resonator is set as M type structure, and resonator is connect with pcb board, and resonator is used to prevent the co-channel interference between first antenna and the second antenna.The utility model has the advantages that double antenna, solves intercoupling, preventing co-channel interference between double antenna signal, and has extensive production and application value in antenna technical field.
Description
Technical field
The utility model relates to antenna technical field more particularly to a kind of PCB antennas of high-isolation 2.4G double antenna.
Background technique
With the development of society, transmission of the people to data, the shared of information has higher demand.WLAN router
Occur so that cable network signal is converted into wireless network signal, sharing for network data is more convenient with transmission.Nowadays
The miniaturization of WLAN router, wireless penetration have been more in line with the demand in epoch, and a kind of MIFI (Mobile WIFI) wireless router is just
Occur, it has outside the function of conventional router, and what is more attracted eyeball is it convenient for carrying, and can be total to whenever and wherever possible
Enjoy network hotspot.MIFI developing direction is miniaturization, easy to carry, brings and easily wants simultaneously for internal structure and function
Ask harsher, for radio-frequency antenna design environment it is increasingly complex with it is harsh, for present MIMO technology, this is prominent
Out the drawbacks of, is particularly evident.Currently on the market there is isolation deficiency in most of MIFI radio-frequency antennas.
Summary of the invention
For the above, the utility model provides a kind of double antenna, solves intercoupling, preventing between double antenna signal
The only PCB antenna of the high-isolation 2.4G double antenna of co-channel interference.
The technical solution of the utility model is as follows: a kind of PCB antenna of high-isolation 2.4G double antenna, including PCB plate,
First antenna, the second antenna, resonator；The first antenna, the second antenna are set as inverted f structure, and first antenna, the second antenna
It is equipped with the connecting pin of feed point end and connecting PCB board；The resonator is set as M type structure, and resonator is connect with pcb board, and humorous
Vibration device is used to prevent the co-channel interference between first antenna and the second antenna.
Preferably, the first antenna, the second antenna, which respectively correspond, is arranged on pcb board top, and the resonator is located at the
Between one antenna, the second antenna.
Using the above scheme, the beneficial effects of the utility model are:
The first antenna of the utility model, the second antenna, which respectively correspond, to be arranged on pcb board top, and the resonator is located at the
Between one antenna, the second antenna；It is such design first antenna, the second antenna between the two, embedded resonator in order to,
Wave trap is served as in first antenna, the second antenna 2.4GHz frequency range, in addition can be captured close between first antenna and the second antenna
Field radiation, to effectively reduce intercoupling between first antenna, the second antenna.Therefore the utility model has double days
The beneficial effect for intercoupling, preventing co-channel interference between line, solution double antenna signal.
Detailed description of the invention
Fig. 1 is the overall structure diagram of the utility model.
Specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
Shown in referring to Fig.1, the utility model provides a kind of PCB antenna of high-isolation 2.4G double antenna, including including PCB
Plate 3, first antenna 1, the second antenna 2, resonator 4；The first antenna 1, the second antenna 2 are set as inverted f structure, and first day
Line 1, the second antenna 2 are equipped with the connecting pin 11 of feed point end 12 and connecting PCB board；The resonator is set as M type structure, resonator
4 connect with pcb board 3, and resonator 4 is used to prevent the co-channel interference between first antenna 1 and the second antenna 2.
The first antenna 1, the second antenna 2, which respectively correspond, to be arranged on 3 top of pcb board, and the resonator 4 is located at first day
Between line 1, the second antenna 2.
Embodiment
First antenna 1, the second antenna 2 respectively correspond be arranged on 3 top of pcb board, the resonator 4 be located at first antenna 1,
Between second antenna 2；Such design first antenna 1, the second antenna 2 between the two, be embedded in resonator 4 in order to the
Wave trap is served as on one antenna 1,2 2.4GHz frequency range of the second antenna, in addition can be captured between first antenna 1 and the second antenna 2
Near-field thermal radiation, to effectively reduce intercoupling between first antenna 1, the second antenna 2.
The above is only the preferred embodiments of the present utility model only, is not intended to limit the utility model, all practical at this
Made any modifications, equivalent replacements, and improvements etc., should be included in the guarantor of the utility model within novel spirit and principle
Within the scope of shield.
