Wherein μ is relative permeability, and ε is relative dielectric constant, and μ and ε are collectively referred to as electromagnetic parameter.Experiment showed, when electromagnetic wave passes through refractive index dielectric material heterogeneous, can be to the big direction deviation of refractive index.Under the certain situation of relative permeability (usually near 1), refractive index is only relevant with dielectric constant, under the situation that first base material is selected, utilize the arbitrary value (within the specific limits) that only can realize super material cell refractive index to the first artificial micro-structural of electric field response, under this center of antenna frequency (12.5GHZ), utilize simulation software, as CST, MATLAB etc., obtain the situation that the dielectric constant of the artificial micro-structural (the alabastrine metal micro structure in plane as shown in Figure 5) of a certain given shape changes along with the refractive index variable of topology by emulation, can list data one to one, the core layer lamella 11 that the specific refractive index that can design us needs distributes, in like manner can obtain the refraction index profile of impedance matching layer lamella, thereby obtain the refraction index profile of whole super material panel 100.
Among the present invention, the structural design of core layer lamella can obtain by Computer Simulation (CST emulation), and is specific as follows:
That (1) determines first metal micro structure adheres to base material (first base material).During this was bright, first prebasal plate of described first base material adopted identical FR-4 composite material to make with first metacoxal plate, and described FR-4 composite material is made has a predetermined dielectric constant, and for example dielectric constant is 3.3 FR-4 composite material.
(2) size of definite super material cell.The size of the size of super material cell is obtained by the centre frequency of antenna, utilizes frequency to obtain its wavelength, gets less than 1/5th a numerical value of wavelength length C D and the width KD as super material cell D again.Among the present invention, described super material cell D is the square platelet that 2.5mm, thickness HD are 0.818mm for long CD and wide KD as shown in Figure 2.
(3) determine material and the topological structure of metal micro structure.Among the present invention, the material of metal micro structure is copper, and the topological structure of metal micro structure is the alabastrine metal micro structure in plane shown in Figure 5, and its live width W is consistent everywhere; Topological structure herein refers to the basic configuration that topology develops.
(4) determine the topology parameter of metal micro structure.As shown in Figure 5, among the present invention, the topology parameter of the alabastrine metal micro structure in plane comprises the live width W of metal micro structure, the length a of the first metal wire J1, the length b of first F1 of metal branch.
(5) determine the differentiation restrictive condition of the topology of metal micro structure.Among the present invention, the differentiation restrictive condition of the topology of metal micro structure has, the minimum spacing WL between the metal micro structure (namely as shown in Figure 8, the distance of the long limit of metal micro structure and super material cell or broadside is WL/2), the live width W of metal micro structure, the size of super material cell; Because the processing technology restriction, WL is more than or equal to 0.1mm, and same, live width W is greater than to equal 0.1mm.Among the present invention, WL gets 0.1mm, and W gets 0.3mm, and super material cell is of a size of the long and wide 2.5mm that is, thickness is 0.818mm, and this moment, the topology parameter of metal micro structure had only a and two variablees of b.The passing through as Fig. 8 of the topology of metal micro structure corresponding to a certain characteristic frequency (for example 12.5GHZ), can obtain a continuous variations in refractive index scope to differentiation mode shown in Figure 9.
Particularly, the differentiation of the topology of described metal micro structure comprises two stages (basic configuration that topology develops is metal micro structure shown in Figure 5):
Phase I: according to developing restrictive condition, under the situation that the b value remains unchanged, a value is changed to maximum from minimum value, the metal micro structure in this evolution process is " ten " font (except when a gets minimum value).In the present embodiment, the minimum value of a is 0.3mm (live width W), and the maximum of a is (CD-WL), i.e. 2.5-0.1mm, and then the maximum of a is 2.4mm.Therefore, in the phase I, the differentiation of the topology of metal micro structure as shown in Figure 8, namely be the square JX1 of W from the length of side, develop into maximum " ten " font topology JD1 gradually, in " ten " font topology JD1 of maximum, the first metal wire J1 and the second metal wire J2 length are 2.4mm, and width W is 0.3mm.In the phase I, along with the differentiation of the topology of metal micro structure, the refractive index of the super material cell corresponding with it increase continuously ((respective antenna one characteristic frequency), when frequency is 12.5GHZ, the minimum value n of the refractive index of super material cell correspondence
MinBe 1.91.
Second stage: according to developing restrictive condition, when a was increased to maximum, a remained unchanged; At this moment, b is increased continuously maximum from minimum value, the metal micro structure in this evolution process is the plane flakes.In the present embodiment, the minimum value of b is 0.3mm (live width W), and the maximum of b is (CD-WL-2W), i.e. 2.5-0.1-2*0.3mm, and then the maximum of b is 1.8mm.Therefore, in second stage, the differentiation of the topology of metal micro structure as shown in Figure 9, namely from " ten " font topology JD1 of maximum, develop into the maximum alabastrine topology JD2 in plane gradually, the alabastrine topology JD2 in the plane of maximum herein refers to that the length b of first J1 of metal branch and second J2 of metal branch can not extend again, otherwise the first metal branch and the second metal branch will take place to intersect, and the maximum of b is 1.8mm.At this moment, first metal wire and the second metal wire length are 2.4mm, and width is 0.3mm, and the length of the first metal branch and the second metal branch is 1.8mm, and width is 0.3mm.In second stage, along with the differentiation of the topology of metal micro structure, the refractive index of the super material cell corresponding with it increases (respective antenna one characteristic frequency) continuously, when frequency is 12.5GHZ, and the maximum n of the refractive index of super material cell correspondence
MaxBe 5.6.
The variations in refractive index scope (1.91-5.6) that obtains super material cell by above-mentioned differentiation satisfies the design needs.Do not satisfy the design needs if above-mentioned differentiation obtains the variations in refractive index scope of super material cell, for example maximum is too little, then changes WL and W, and emulation again is up to obtaining the variations in refractive index scope that we need.
According to formula (1), after a series of super material cell that emulation is obtained is arranged according to its corresponding refractive index (in fact being exactly a plurality of first artificial micro-structural the arranging on first base material of different topology shape), can obtain core layer lamella of the present invention.
In like manner, can obtain impedance matching layer lamella of the present invention.
