And in multiple interactive dielectric segments 30, the dielectric constant of two interactive dielectric segments 30 at least within is different.Wherein, interaction
The quantity of dielectric segments 30 could be arranged to odd number, it is also possible to be set to even number.For example, following several embodiment party can be divided into
Formula, the in full description to the description of interaction dielectric segments 30 are mainly based upon what identical this precondition of shape was made：
Mode one：
As shown in Fig. 4, Fig. 5, Fig. 6, when the quantity of interaction dielectric segments 30 is odd number, in middle interactive dielectric segments 30 being
The each pair interaction dielectric segments 30 of heart axle, at least identical symmetric position in central shaft both sides have identical dielectric constant, and the both sides
The dielectric constant of interactive dielectric segments 30 be different from the dielectric constant of middle interactive dielectric segments 30.Preferably, except middle friendship
Mutually beyond dielectric segments 30, the dielectric constant of each pair interaction dielectric segments 30 of central shaft both sides difference symmetric position is also different,
Now, for convenience of understanding, each pair is interacted dielectric segments 30 as a comparison unit.Wherein, for convenience of produce, can away from
The dielectric constant of the interactive dielectric segments 30 on central axis direction is gradually reduced.For example, to interact the quantity of dielectric segments as 5
As a example by, each interactive dielectric segments dielectric constant from left to right can be selected successively as (1) 2.5,4.4,6.5,4.4,2.5；(2)
2.5、3.9、4.4、3.9、2.5；(3) 2.1,3.6,4.4,3.6, any one in 2.1 3 kind of combination to be meeting different need
Ask.Certainly, according to the actual requirements, the different dielectric constant combination of other situations can also be arranged to, does not make excessive limit herein
System.
This kind of mode, the quantity of interaction dielectric segments 30 is set to odd number and multiple interactive dielectric segments 30 are with middle interaction
Axle centered on dielectric segments 30, is symmetrically distributed in the both sides of central shaft, arranges fairly simple, and product structure is easily realized, also, is moved
The size of phase device is less.
Mode two：
For compared to mode one, each interaction dielectric segments 30 can be set to into less size in mode two, than
Such as, in mode one, the area of an interactive dielectric segments 30 is S, and in mode two is (1/3) S's by arranging 3 areas

(1) quantity of interaction dielectric segments 30 is odd number, still the axle centered on middle interactive dielectric segments 30, and remaining interaction is situated between
Electric section 30 does asymmetric setting in central shaft both sides, by the interaction fine setting in position of dielectric segments 30 and then amount of phase shift is carried out
Fine setting, disclosure satisfy that the greater demand of user.
(2) quantity of interaction dielectric segments 30 is even number, middle two interactive dielectric segments 30 it is equivalently-sized, and more than two
Axle centered on the interactive dielectric segments 30 of side, also, the centrage between middle two interactive dielectric segments 30, interaction Jie of both sides
Electric section 30 can also do asymmetric setting in central shaft both sides, it is also possible to by the fine setting in position of interaction dielectric segments 30 further
Amount of phase shift is finely adjusted, the greater demand of user is disclosure satisfy that.
In mode two, the dielectric constant of at least middle interactive dielectric segments 30 interacts the dielectric constant of dielectric segments 30 with remaining
It is different.
Refering to Fig. 7 and Fig. 8, in a concrete application embodiment, each interaction dielectric segments 30 can at least by two parts
Combine, each several part is made up of the material of differing dielectric constant, and at least two of which interacts the dielectric constant of dielectric segments 30
It is different, also, 30 shape and size of each interactive dielectric segments for combining are identical.For example, as shown in fig. 7, each
Interaction dielectric segments 30 can be by being stacked group using Part I 31, Part II made by differing dielectric constant material about 32
Into each single 30 shape of interactive dielectric segments for being stacked composition is identical, equivalently-sized (i.e. thickness is identical), every when what is combined
When the dielectric constant of individual single interactive dielectric segments 30 meets the dielectric constant that computer optimization mode is calculated, equally can solve the problem that
The technical problem to be solved.Also, same interactive dielectric segments 30 are set to form so that some is stacked, can
Dielectric constant is adjusted according to different phase shift demands, such as, when needing larger dielectric constant, one or more can be used
Dielectric constant is larger but part less than desired value based on part, then that one or more dielectrics are stacked in base component is normal
Fine setting is realized in the less part of number, and then is assembled into a complete interactive dielectric segments 30.
Refering to Fig. 9, in a concrete application embodiment, the quantity of correspondence interaction dielectric segments 30 on feeder line 2, is provided with
Breach 8, interaction dielectric segments 30 at least partly block the breach 8 of relevant position on feeder line 2 when Chong Die with 2 dynamic of feeder line.Wherein, often
Individual interactive dielectric segments 30 are also not necessarily required to one breach 8 of correspondence, and 8 size of breach, shape are also not necessarily identical, for scarce
The design of 8 each parameters of mouth can also be obtained according to computer optimization mode.By breach 8 is set up on feeder line 2, the breach 8 can
Impedance matching is participated in, is made standing wave bandwidth be optimal state, and is reduced the reflection that signal is conducted on feeder line 2.
Furthermore it is possible to breach 8 is replaced with into boss (not shown), wherein, the position of boss is different from the position of breach 8.
When interaction dielectric segments 30 covered area Chong Die with 2 dynamic of feeder line reaches maximum, at least part of two adjacent interactive dielectrics
Boss is provided with the corresponding feeder line of interval location 2 between section 30.Specifically, i.e., boss is still arranged on feeder line 2, and boss sets
It is placed between adjacent two interactions dielectric segments 30 on corresponding feeder line 2, even if interaction dielectric segments 30 are Chong Die with 2 dynamic of feeder line being covered
Area reach maximum, interaction dielectric segments 30 will not also block boss.Quantity, dimension and shape for boss can also be by
Computer optimization mode determines, does not make concrete restriction to which.Boss is set up on feeder line 2, is conducive to standing wave to debug.
In above-mentioned embodiment, when the distance between each adjacent two interactions dielectric segments 30 are set to smaller value, the phase shift is filled
Put the use that can meet 1710～2690MHz of high band；When increasing the distance between each adjacent two interactions dielectric segments 30, the phase shift
Device can be extended to the use of 698～960MHz of low-frequency range, and the suitable distance between each adjacent two interactions dielectric segments 30 is specifically regarded
Computer optimization mode is determined.
