[embodiment 3]
In the present embodiment, electric identical two binary array antennas conllinear are up and down arranged, and one fen four power splitter of middle insertion make four radiator constant amplitude homophase feeds, as shown in Figure 4, have so just formed quaternary high-gain broadband omnidirectional antenna battle array.Signal from communication equipment passes the input that location-plate 13 inserts one minute four power splitter 26 through main feeder 12, the output of power splitter 26 is divided into four the tunnel, giving up and down by feeder cable 7,8,20 and 21, four radiating doublets carry out constant amplitude homophase feed, four feeder cables 7,8,20 and 21 enter wherein by the holes that lead in the battalion 11 at the center respectively, the underarm edge that radiator is passed at the multiple place of wearing again respectively enters in the sleeve oscillator, to the upper arm its lower edge, its internal and external conductor is welded on the edge of upper arm and the inward flange distributing point 15,17 and 22,24 places of underarm respectively.After the signal from communication equipment entered main feeder 12, all radiating doublets all were energized, and induce surface current on radiating doublet, and then radiated electromagnetic wave like this, passed the PVC radome that surrounds radiator, propagated into free space and went.
In the present embodiment, each unit consists of, as shown in Figure 1, be element antenna structural representation among the invention embodiment: main feeder 12 passes from center support copper pipe 11, underarm bottom edge from main element 3 penetrates again, distributing point along the underarm inward flange to upper arm lower limb step place connects, inside and outside like this with constitute feed Ba Lun 6 up and down, Ba Lun 6 makes main element antenna 3 reach the full frequency band coupling basically, in order further to improve coupling, make the upper arm of main element extend to outer adjustment sheet 2, the end of outer adjustment sheet 2 adds short-circuit piece 4, so just reach the effect of full frequency band coupling, the outer adjusting of configuration loads the low-frequency range matching properties is improved like this, stretching out sheet probe 5 from the bottom surface middle part of main element 3 simultaneously stretches in the underarm, but do not contact underarm, as interior adjustment sheet, owing to increased interior adjusting reactance compensation, the high frequency characteristics of main element 3 is improved (VSWR＜1.4), the upper end of main element 3 is inserted to go up to locate and is covered in 1, in the positioning plate 13, insert in the radomes 14 under insert the lower end of main element 3, carry out capping then by locating 1 and 13 up and down.Fig. 2 is the edge feeding technique partial enlarged drawing among the invention embodiment, and wherein, 15 is that distributing point 1,16 is a shielding layer grounding 1.In like manner, 17 is that distributing point 2,18 is a shielding layer grounding 2; 22 is that distributing point 3,23 is a shielding layer grounding 3; 24 is that distributing point 4,25 is a shielding layer grounding 4.19 is illuminating line.
[embodiment 4]
Similar to Example 3, embodiment 3 is a quaternary high-gain broadband omnidirectional antenna battle array, similarly, utilize corresponding power splitter can form high-gain omni-directional antenna battle arrays hexa-atomic or different gains such as eight yuan, these days, the array element distance of linear array can equate, in order to form better directivity and to reduce and pay lobe, also can carry out suitable adjustment to array element distance, become unequal-interval high performance omni-directional antenna battle array, with the network optimization that realizes that the sub-district covers, need to prove, in the quaternary battle array shown in the accompanying drawing 4, middle power splitter has just in time occupied the position and the size of an antenna element, is equivalent to 5 yuan of battle arrays and has removed center cell, only antenna gain and beamwidth is had a little influence.
In addition, this programme also has following innovative characteristics:
The edge feeding technique
Total array antenna adopts the parallelly feeding mode, but for each element antenna is to adopt the edge feed method as shown in Figure 2, feeder cable passes from central tube, penetrate at sleeve oscillator underarm edge, arrive get out of a predicament or an embarrassing situation (the gradual change part) of sleeve oscillator upper arm along the underarm edge, inner wire just is welded on step gradual change place, outer conductor is welded on place, sleeve oscillator underarm inside edge, feed Ba Lun balanced controls have so just been formed, this feed form has guaranteed full frequency band standing-wave ratio＜2, it is a kind of broadband feed Ba Lun method, increase along with the antenna element number, each distributing point of feed is staggered by this way, with the improvement of the not garden degree performance that helps omnidirectional antenna azimuth plane directional diagram.
Oscillator radiator distributed load technology
For the impedance matching property that improves low frequency end as shown in Figure 1, be mountain font extension socket outer wall at last in mountain word top short circuit at sleeve oscillator upper arm, this measure standing wave reduces to＜and 1.5, played the effect of fine setting, so just make that underarm becomes a kind of dissymmetrical structure on the sleeve oscillator, effectively guaranteed broadband character, the mountain font accounts for 1/2 circle for best.
Compensation technique in the radiator reactance
Stretch out a sheet probe as accompanying drawing 1 to the inwall of bottom main element at main element lower surface medium position, sheet probe does not contact with sleeve oscillator underarm end face, present upright vacant state, this measure has further improved high frequency characteristics, makes VSWR＜1.4 of high frequency
Though the invention with preferred embodiment openly as above; but they are not to be used for limiting the invention; anyly have the knack of this skill person; in the spirit and scope that do not break away from the invention; from when can doing various variations or retouching, so being as the criterion of should being defined with the application's claim protection range of the protection range of the invention.
