In order to make technical matters to be solved by this invention, technical scheme and beneficial effect clearer, clear,, the present invention is further elaborated below in conjunction with drawings and Examples.Should be appreciated that specific embodiment described herein only in order to explanation the present invention, and be not used in qualification the present invention.

The present invention proposes minimum array element notion, it can provide enough quantity of information for the scattering matrix that simulates the Pindrill array.At first from the Pindrill array, choose or construct the minimum array element of a structure minimum, then minimum array element is carried out modeling and simulating and extract scattering matrix, utilize the architectural feature between minimum array element and the Pindrill array to determine that the relation of minimum unit array scattering matrix and Pindrill array scattering matrix simulates the scattering matrix of whole array at last.

The preparation method of a kind of connector Pindrill array scattering matrix provided by the invention, described method comprises:

Step 1, from the Pindrill array, select the array of a structure minimum, form minimum array element.

Wherein, minimum array element is the design feature according to the Pindrill array, from the Pindrill array, select the array of a structure minimum, just can construct the Pindrill array by the combination between this minimum array element, the physical arrangement of this minimum array element is determining its electromagnetic field to distribute, and is just determining also whether it contains enough the be needed reflection of can not ignore of match Pindrill array, transmission, S parameter such as crosstalk, and guarantee enough degree of accuracy.

Step 2, minimum array element is carried out modeling and simulating extract scattering matrix.

Minimum array element is carried out modeling and carry out the simulated extraction scattering matrix in 3 D electromagnetic emulation tool HFSS.

Step 3, utilize the architectural feature between minimum array element and the Pindrill array to determine that the relation of minimum unit array scattering matrix and Pindrill array scattering matrix simulates the scattering matrix of whole array.

The scattering matrix of Pindrill array is a n * n rank matrix (n is the port number of array, and concrete structure is as follows) that is made of scattering parameter (S parameter), wherein, and element S _IjBe called scattering parameter.

$\left\{\begin{array}{cccc}{S}_{11}& S_{12}& ...& S_{1n}\\ S_{21}& S_{22}& ...& S_{2n}\\ M& M& O& M\\ S_{n1}& {\mathrm{<figure-callout\; id="2"\; label="S\; n"\; filenames="HDA0000041311880000011.png"\; state="\{\{state\}\}">S</figure-callout>}}_n& ...& S_{\mathrm{nn}}\end{array}\right\}$

Wherein, in any line parameter, count S by reflecting system _Ii, the transmission coefficient S on the signal transmission path _Ij, the transmission coefficient S that can not ignore that causes by crosstalking between the port _Ij, very little negligible transmission coefficient S crosstalks between the port _IjConstitute.

Among the present invention, above-mentioned S parameter is divided into 4 classes: reflection coefficient, the transmission coefficient on the signal transmission path, the transmission coefficient of can not ignore that causes by crosstalking between the port, the very little negligible transmission coefficient of crosstalking between the port.So,, just can obtain the scattering matrix of Pindrill array according to above-mentioned matrix construction form by simulating this 4 class S parameter.

Provide the characteristics and the approximating method of this 4 class S parameter below in detail:

The reflection coefficient match of each port: this parameter mainly is by the decision of the impedance operator of Pindrill itself, as long as choose the reflection coefficient that the reflection coefficient of the structure same port that is positioned at connector the same side promptly can be used to replace the match port of wanting.Method is as follows:

Step a1, determine to want in the Pindrill array port of match, for example need the reflection coefficient S of match port i _Ii

Step a2, in minimum array element, find the port j consistent with port i structure, the consistent size that is meant port j of structure own, and the distribution of port on every side is consistent with port i with distance.

Step a3, in the scattering matrix that minimum array element match obtains, find the reflection coefficient S of port j _Jj, wherein, the match of minimum array element is to use the modeling and simulating instrument to realize.

Step a4, use S _JjReplace S _Ii, can obtain the reflection coefficient of port i.

Step a5, repeating step a1 be to a4, the reflection coefficient of all of the port in obtaining the Pindrill array.

The transmission coefficient match of can not ignore that causes by crosstalking between the port: this parameter is to be determined by the relative locations of structures between two ports, therefore during the transmission coefficient between two ports that match need be paid close attention to, need find two ports that have in the minimum array with spline structure, can realize the crosstalk match of transmission coefficient of port.Method is as follows:

Step b1, determine to want in the Pindrill array two ports of match, port i is to the transmission coefficient S that crosstalks of port j _Ij

Step b2, in minimum array element, find port k consistent and port l with port i and port j structure, the consistent size that refers to port k and port l of the structure here own, the relative position of port k and port l and distance, and the size of port is all consistent with port i and port j with distance around the two-port.

Step b3, in the scattering matrix that minimum array element match obtains, find the transmission coefficient S that crosstalks of port k and port l _Kl

Step b4, use S _KlReplace S _Ij, can obtain the crosstalk transmission coefficient of port i to port j.

Step b5, repeating step b1 be to b4, the transmission coefficient of crosstalking in obtaining the Pindrill array between all of the port.

The very little negligible transmission coefficient match of crosstalking between the port: because the value of the very little negligible transmission coefficient of crosstalking between the port trends towards zero, so in tolerable accuracy requirement scope, can directly use 0 value to replace.

Transmission coefficient match on the signal transmission path: scattering matrix passive, linear, that ignore the loss network satisfies law of conservation of energy, promptly to same port, the energy that flows into this port equals from this port reflection and the energy sum that flows to other all of the port, just scattering matrix equals 1 with the quadratic sum of the mould of the S parameter of delegation or same row, shown in following formula (1):

S ^*S＝E (1)

Wherein: S ^*Be the conjugate matrices of S parameter matrix.

Therefore, expect the transmission coefficient on the transmission path, just can be according to the S parameter that has obtained (the reflection S parameter of front, the S parameter of crosstalking, negligible S parameter), quadratic sum in conjunction with the mould of this 4 class S parameter equals 1 (as following formula 2) again, just can calculate the mould value of the transmission coefficient on the signal transmission path, and phase information can be replaced by the phase place of identical Pindrill structure.

Wherein, n is total port number.

Concrete approximating method is as follows:

Each port i exists another unique port j to constitute the transmission path of signal with it, and also just there is a unique transmission coefficient S in expression _IjIt is the transmission coefficient on the signal transmission path.All there is a transmission coefficient S on the transmission path in each line parameter in scattering matrix _Ij, because S _IjBe a plural number, constitute, so match S by mould value and phase value _IjMethod as follows:

Step c1, the match of mould value: under the situation that three kinds of S parameters all obtain, utilize following formula 2 to calculate the mould value in front.

Step c2, phase value match:

Phase value on the transmission path depends on the structure with array, in minimum array element, find and i, the k port and the l port of j port transmission path structure unanimity, the consistent size that refers to k and l port of the structure here own, the relative position of k and l port and distance, and the size of port is all consistent with i and j port with distance around the two-port.Use S _KlPhase value needing to replace the phase value of the transmission coefficient of match.

Step c3, repeating step c1 and step c2, the transmission coefficient of all of the port on a transmission path in obtaining the Pindrill array.

For the principle that can better understand the present invention, below provide a specific embodiment.

At the Pindrill Array Model of certain connector, at first analyze the architectural feature of Pindrill array, determine to comprise the minimum unit array of enough information.This minimum unit array is carried out modeling and simulating, extract the scattering matrix of minimum unit.The scattering matrix that utilizes minimum unit with and simulate the scattering matrix of whole array with the corresponding relation of Pindrill array scattering matrix.Describe implementation step in detail below in conjunction with accompanying drawing.

Step S01 selects the array of a structure minimum from the Pindrill array, form minimum array element.

Please refer to Fig. 2 and Fig. 3.Certain connector Pindrill Array Model is a stereoscopic model, port in this model is evenly distributed in the both sides of model, and be that symmetry exists, the floor map of a side ports wherein that shown in Figure 2 is just needs to extract the synoptic diagram of the Pindrill array of scattering matrix.Each can be used as difference through hole to white via hole among Fig. 2, also can be used as the single-ended signal via hole, and the black via hole is represented the ground via hole.Analyzing this Pindrill array structure, can obtain providing the minimum array element of enough information, is the floor map of a certain side ports of minimum array element as shown in Figure 3.

Step S02 carries out minimum array element shown in Figure 3 modeling and carry out the simulated extraction scattering matrix in 3 D electromagnetic emulation tool HFSS, obtains the scattering matrix of minimum array element.

Step S03, the S parameter of the scattering matrix of Pindrill array shown in Figure 2 and minimum array element shown in Figure 3 is divided into 4 classes: reflection coefficient, transmission coefficient on the signal transmission path, the transmission coefficient of can not ignore that causes by crosstalking between the port, the very little negligible transmission coefficient of crosstalking between the port.It below is the method that simulates these 4 S parameters.For showing difference, hereinafter will use S ' to represent the S parameter of minimum array scattering matrix.

The match of reflection coefficient: the match of reflection parameters can replace by the reflection coefficient that is positioned at the port of connector the same side in minimum array element scattering matrix.

As shown in Figure 3, actual Array Model is a spatial structure, and shown in Figure 3 is the planimetric map of a certain side of this spatial structure, and all of the port all belongs to a side, and opposite side port and Fig. 3 symmetry exist.

The reflection coefficient of each port all needs match among the figure, here the reflection coefficient S of a key diagram 2 middle ports 5 ₅₅Approximating method, the match of other port is identical therewith, does not just enumerate one by one.

The reflection coefficient S of Fig. 2 middle port 5 ₅₅, in minimum array element shown in Figure 3, find the port 5 ' identical (for the port of distinguishing among Fig. 35 is called port 5 ') with port 5 structures.The structure here is identical to refer to port 5 ' top the ground via hole, below and right-hand signal via is arranged, and the size of these via holes and relative distance are consistent with port 5.In the scattering matrix that minimum array element match obtains, find the reflection coefficient S ' of port 5 ' ₅₅, use S ' ₅₅Replace S ₅₅, can obtain the reflection coefficient S of port 5 ₅₅

According to above method, the reflection coefficient of other port of match.

The match of the transmission coefficient of can not ignore that causes by crosstalking between the port: find two ports that have in the minimum array with spline structure, use the transmission coefficient of the equidirectional of this two-port to replace required match transmission coefficient.The relative position size that the structure here refers to two-port with they around the distribution situation of via hole all consistent.Method is as follows:

At first to determine the pairing transmission coefficient of crosstalking of can not ignore of match port, in minimum array element, find port then with institute's match port same structure, the S parameter of using minimum array element match to obtain replaces the transmission coefficient of crosstalking of required match, can obtain the transmission coefficient of crosstalking between the port.

Port 5 with Fig. 2 is that example illustrates: port 5 needs the S parameter of can not ignore of match to have 6, is respectively: port 7 is to the cross-talk parameters S of port 5 _5,7, port 8 is to the cross-talk parameters S of port 5 _8,5, port one 7 is to the cross-talk parameters S of port 5 _17,5, port one 8 is to the cross-talk parameters S of port 5 _18,5, port one 9 is to the cross-talk parameters S of port 5 _19,5, port 20 is to the cross-talk parameters S of port 5 _20,5, wherein, port 7, port one 7, port one 9 are the ports that show in Fig. 2, port 8, port one 8, port 20 are the ports that do not show (not shown) that exist with Fig. 2 symmetry.Find in the minimum array element in Fig. 3 and the identical port 5 ' of port 5 structures, structure is identical to be illustrated in step S04.With port 7 to port 5 structures corresponding be port 7 ' to port 5 ', use S ' _7,5Replace S _7,5With port 8 to port 5 structures corresponding be port 8 ' to port 5 ', use S ' _8,5Replace S _8,5With port one 7 to port 5 structures corresponding be port one 3 ' to port 5 ', use S ' _13,5Replace S _{17 ' 5}With port one 8 to port 5 structures corresponding be port one 4 ' to port 5 ', use S ' _14,5Replace S _18,5With port one 9 to port 5 structures corresponding be port one 5 ' to port 5 ', use S ' _15,5Replace S _7,5With port 20 be 20 ' to port 5 ' to port 5 structure corresponding port, use S ' _20,5Replace S _7,5

Use above same method match to obtain the transmission coefficient of crosstalking of can not ignore of all of the port.

Crosstalk between the port match of very little negligible transmission coefficient: trend towards zero in the value reality of this type of transmission coefficient, satisfying under the accuracy requirement situation and can directly replace with 0 value, promptly behind the transmission coefficient of having determined can not ignore of crosstalking, the remaining transmission coefficient of crosstalking uses 0 value to replace.

The match of the transmission coefficient on the signal transmission path: according to S parameter (the reflection S parameter of the same row of scattering matrix, the S parameter of crosstalking, negligible S parameter), quadratic sum in conjunction with the mould of this 4 class S parameter equals 1 (as following formula 2) again, just can calculate the mould value of the transmission coefficient on the signal transmission path, phase information can be replaced by the phase place of identical Pindrill structure.

Wherein, n is total port number.

Concrete approximating method is as follows:

Each port i exists another unique port j to constitute the transmission path of signal with it, and also just there is a unique transmission coefficient S in expression _IjIt is the transmission coefficient on the signal transmission path.All there is a transmission coefficient S on the transmission path in each line parameter in scattering matrix _Ij, because S _IjBe a plural number, constitute, so match S by mould value and phase value _IjCan be divided into for two steps, method is as follows:

Step c1, the match of mould value:

Under the situation that three kinds of S parameters all obtain, utilize following formula to calculate in front:

Wherein, n is total port number.Reflection coefficient S with i in capable _Ii, the transmission coefficient S that can not ignore _Ij(i is not a port relative on the transmission path with j), insignificant transmission coefficient use 0 value to replace, and are brought into the mould value that match in the above-mentioned formula obtains transmission coefficient.

Step c2, phase value match:

Phase value on the transmission path depends on the structure with array, in minimum array element, find and i, the k port and the l port of j port transmission path structure unanimity, the consistent size that refers to k and l port of the structure here own, the relative position of k and l port and distance, and the size of port is all consistent with i and j port with distance around the two-port.Use S _KlPhase value needing to replace the phase value of the transmission coefficient of match.

Port 5 with Fig. 2 is the match that example illustrates port 5 transmission coefficients below:

The transmission coefficient of port 5 refers to the S of port 5 to port 6 _6,5, with S _6,5S parameter with delegation has S _6,1, S _6,2... S _{6, n}, wherein n is the port sum.Reflection coefficient S in this delegation _6,6, transmission parameter S crosstalks _{6, i}Wherein i is for removing other port of port 6 and port 5, all crosstalking between transmission coefficient match of can not ignore that has caused by crosstalking between the match of above-mentioned reflection coefficient, port and the port obtains in the very little negligible transmission coefficient match, utilizes formula 2 just can obtain S again _6,5The mould value.What have same structure with port 5 is port 5 ' in the minimum array element shown in Fig. 3, uses the transmission coefficient S ' of port 5 ' _6,5Phase value replace S _6,5Phase value, just obtained the transmission coefficient S of port 5 with mould value combination _6,5

Use above same method match to obtain the transmission coefficient of all of the port.

Step S04, the 4 class S parameters that more than obtain just can obtain the scattering matrix of Pindrill array according to following matrix construction form.

$\left\{\begin{array}{cccc}{S}_{11}& S_{12}& ...& S_{1n}\\ S_{21}& S_{22}& ...& S_{2n}\\ M& M& O& M\\ S_{n1}& {\mathrm{<figure-callout\; id="2"\; label="S\; n"\; filenames="HDA0000041311880000011.png"\; state="\{\{state\}\}">S</figure-callout>}}_n& ...& S_{\mathrm{nn}}\end{array}\right\}$

Wherein, n is total port number, in any line parameter, counts S by a reflecting system _Ii, the transmission coefficient S on signal transmission path _Ij, the transmission coefficient S that can not ignore that causes by crosstalking between the port _Ij, very little negligible transmission coefficient S crosstalks between the port _IjConstitute.The S parameter that each port match is obtained has just obtained whole Pindrill array scattering matrix after by above form match.
