Description

The miniaturized multifrequency section moves the fixed station omnidirectional antenna
Technical field
The utility model relates to the mobile communication technology field, relates to a kind of double frequency or multi-frequency omni-directional antenna in particular.
Background technology
The double frequency of prior art, multi-frequency omni-directional antenna are because frequency range is many and the wide deviation in roundness of radiation pattern horizontal plane that causes of bandwidth can not reach the requirement that we want simultaneously in corresponding frequency range; This has also just caused the energy emission of antenna on horizontal plane even inadequately, will influence client's practical effect sometimes.The main cause that this situation occurs is exactly because the technology of tradition control antenna pattern horizontal plane deviation in roundness can only guarantee the high band or the deviation in roundness of low-frequency range; And can not guarantee the deviation in roundness of high and low frequency range internal antenna antenna pattern horizontal plane simultaneously; Conventional omni-directional double frequency or multiband aerial mainly are to lean on the metal tube of one 1/4 wavelength to suppress negative-phase sequence curent; Thereby guarantee that antenna is can radiation even at horizontal plane, promptly the deviation in roundness of radiation pattern horizontal plane can be guaranteed.But along with the continuous rising of price, today that antenna industry competition simultaneously is growing more intense, it is particularly important that the cost that when guaranteeing antenna performance, adopts equivalence techniques application simple antenna structure to reduce antenna just shows.
Summary of the invention
It is little that the purpose of the utility model is exactly that provide for the deficiency that solves prior art a kind of has the antenna volume of assurance; Bandwidth; Gain, the miniaturized multifrequency section that can reduce the cost of antenna under the good condition of directional diagram significantly moves the fixed station omnidirectional antenna.
The utility model is to adopt following technical solution to realize above-mentioned purpose: a kind of miniaturized multifrequency section moves the fixed station omnidirectional antenna; Comprise antenna oscillator and link; It is characterized in that; Said antenna oscillator mainly is made up of the last radiating doublet on top and the chokes oscillator of bottom, is connected with equivalent sleeve between last radiating doublet and the chokes oscillator, has plastic medium to load on the chokes oscillator.
As further specifying of such scheme, said antenna oscillator adopts the metallic conductor of circle, semicircle or sheet as chokes oscillator and radiating doublet.
The parts of said formation antenna oscillator all adopt half of metal tube structure.
The plastic medium that loads on the said chokes oscillator is the plastic medium pipe; Plastic medium pipe set inside coaxial cable; The end of equivalence sleeve is provided with the ambroin fixed cover, is provided with the coaxial line heart yearn crimping point corresponding with said coaxial cable in the ambroin fixed cover.
Be provided with chokes feedthrough voltage contact between said equivalent sleeve and the chokes oscillator.
The crimping mode is adopted in connection between the said link.
Said upward radiating doublet length and equivalent length sleeve sum are 1/4 wavelength of antenna low-frequency range; The chokes oscillator length is the ratio of the relative electric constant evolution with loaded medium of low frequency 1/4 wavelength.
Said antenna oscillator adopts other material pipe of semicircle copper pipe or plating metal on surface.
The beneficial effect that the utility model adopts above-mentioned technical solution to reach is:
The utility model adopts the non-tubular shape choke structure to realize the broadband character (impedance bandwidth, directional diagram bandwidth) of conventional sleeve antenna on the basis of traditional antenna technology, has saved material cost simultaneously; Company between oscillator and the feeder line adopts the crimp technology of automation in addition, not only makes simply but also improved the consistency and the reliability of antenna.

Embodiment
As shown in Figure 1; A kind of miniaturized multifrequency section of the utility model moves the fixed station omnidirectional antenna; Comprise antenna oscillator and link; Antenna oscillator mainly is made up of the last radiating doublet 1 on top and the chokes oscillator 2 of bottom, is connected with equivalent sleeve 3 between last radiating doublet 1 and the chokes oscillator 2, and plastic medium loaded tubes 4 is arranged on the chokes oscillator 2.Antenna oscillator can adopt the metallic conductor of circle, semicircle or sheet as chokes oscillator and radiating doublet, and present embodiment adopts half of metal tube structure.Plastic medium loaded tubes 4 set inside coaxial cables 5; The end of equivalence sleeve 3 is provided with ambroin fixed cover 6; Be provided with the coaxial line heart yearn crimping point 7 corresponding in the ambroin fixed cover 6, be provided with true feedthrough voltage contact 8 between equivalent sleeve 3 and the chokes oscillator 2 with said coaxial cable.Last radiating doublet length 1 is 1/4 wavelength of antenna low-frequency range with equivalent sleeve 3 length sums; Chokes oscillator 2 length are the ratio of the relative electric constant evolution with loaded medium of low frequency 1/4 wavelength.Antenna oscillator adopts other material pipe of semicircle copper pipe or plating metal on surface.
The open sleeve antenna of the halfpipe that the utility model adopts has and the complete identical projected area of pipe box tube antenna, so its electrical property has good equivalent action; Chokes oscillator (uneven to the balanced transformation effect) adopts the semicanal form also to have same electromagnetism skin effect; Simultaneously because so it becomes high impedance (open circuit) characteristic endways for low frequency 1/4 wavelength electrical length; Thereby offset the coaxial cable surface current, it also has radiation effects simultaneously.
Above-described only is the preferred implementation of the utility model; Should be understood that; So long as the multiband omnidirectional antenna adopts 1/4 wavelength halfpipe metal tube chokes principle to guarantee the antenna of horizontal plane radiation effect; If the employing present technique realizes omnidirectional wideband antenna and improves the deviation in roundness of antenna pattern horizontal plane that these all belong to the protection range of the utility model.
