Abstract
The present invention relates to the joining method that a kind of frequency selects printed board in antenna house processing technology, and antenna house size larger FSS screen to be spliced together situations in irregular shape suitable for periodic unit.The present invention is according to the contour shape and arrangement regulation of metal unit, it would be desirable to which each frequency-selective surfaces submodule block boundary of splicing is cut into the zigzag of complementary structure, which has the function of positioning in splicing.Jagged cutting mode can also ensure not cutting off metal periodic unit, so as to reduce the discontinuous caused reflection of edge joint position.This joining method allows piece occur by the way of non-overlapping, can reduce the machining accuracy of printed board, so as to reduce processing cost.The short space of edge joint position in the recombination process of antenna house fill naturally as similar in printed board substrate dielectric constant by glued membrane, ensures the high consistency of product and simulation model, and electrical property is easier to ensure that.Simple concatenation effect of the present invention is good, possesses stronger engineering practicability.
Description
Technical field
The invention belongs to antenna microwave fields, and printed board in antenna house process is selected more particularly to a kind of frequency
Joining method.
Background technology
In the stealth technology of radar system, frequency-selective surfaces (Frequency Selective Surface, FSS)
Technology has considerable position.FSS is that one kind is formed on one-dimensional or two dimensional surface by same unit periodic arrangement
Structure, form processing widely used at present is printed circuit technique, and the copper clad layers of substrate are etched to desired metal pattern.
But since FSS design difficulties are big, processing technology is complicated, of high cost, is not widely used in various weapon platforms at present.Its
In one the reason is that cover body physical size is often larger, printed board factory can process both at home and abroad at present whole plate limited area makes
Obtain frequency-selective surfaces needs to splice in the processing of cover body.The widely used overlap joint of FSS screens splicing at present or the shape of straight flange splicing
Formula, this can cause the decline of FSS screen performances to a certain extent, it is difficult to reach the requirement of designer.
The content of the invention
The present invention relates to the joining methods that a kind of frequency selects printed board in antenna house process.This method is different from existing
Some bridging types or straight flange splicing, but the saw-tooth slot of boundary profile complementation is used, it is in irregular shape suitable for periodic unit 1
And the larger FSS screens situation to be spliced together of antenna house size.
To achieve the above object, the technical solution taken of the present invention is:
1st step:The size and outer shape of frequency-selective surfaces submodule needed for determining.For theoretically, each submodule
Shape can be arbitrary, such as rectangle, parallelogram, sector etc..This certain shape is an initial value, is used for
The number and arrangement position of periodic unit 1 are chosen in guidance.Each subblock size, the definite principle of shape are as follows:
1. the size limitation of 2 veneer of printed board processing.The full-size of country's hardboard processing is no more than 1200mm at present.
2. the minimum principle of piece.Anyway, the introducing of piece can all introduce mismachining tolerance therewith.Whole each submodule of cover
Division is reasonable, reduces piece to the greatest extent.
3. the general shape of submodule relies on the shape of whole cover.For example, the submodule of cone-shaped hood is preferably divided into sector, square
The submodule of shape plane radome is preferably divided into rectangle.
4. periodic unit 1 in irregular shape blocks naturally, splicing seams profile 3 is often jagged, if but week
When phase unit 1 blocks naturally border for straight line, it is necessary to artificially design jagged border, principle is not cut off metal unit.
2nd step:According to the original dimension and shape of above-mentioned definite submodule, the exterior contour of periodic unit 1 and week
The spread pattern of phase unit determines the position of the horizontal and vertical number of periodic unit 1 and arrangement.Two neighboring submodule is spelled
Joint profile 3 must geometry complementation.
3rd step:Each submodule is pre-splicing.Each submodule is spliced on suitable mold and frock, blend compounds band
It is bonding along stitching.After making sheet 2 to be printed and foamed core cure, the adhesive tape and that clears up abutting edge stay glue of tearing.
Compared with art methods, its advantage is the present invention:
1. jagged splicing seams profile 3 has positioning function, the connecting method and existing overlap joint or straight flange splicing side
Formula is compared, and splicing is more efficient, and the precision of splicing is converted into the machining accuracy of splicing seams profile 3.
2. splicing seams profile 3 avoids irregular metal pattern, the electrical connectivity of frequency selection cycle unit 1 is enable to protect
It demonstrate,proves, reflection smaller caused by discontinuity at splicing seams profile 3.
3. splicing seams profile 3 allows have certain mismachining tolerance, to the processing essence of printed board compared with other connecting methods
Degree requires lower, serious forgiveness higher.
4. the gap at splicing seams profile 3 is filled naturally by bonded adhesives in the curing process, if selection dielectric constant is close
2 substrate of printed board and Gumming glue film, then the dielectric substrate uniformity of periodic unit 1 is more preferable, and electrical property is easier to ensure that.
Description of the drawings
Fig. 1 is that four pieces of hexagonal rings periodic unit frequency-selective surfaces submodules of the present invention splice schematic diagrames, splicing seams wheel
The printed board submodule geometry of wide both sides is complementary.
Fig. 2 is that hexagonal rings periodic unit of the present invention is spelled in the zigzag of two dimensional surface (finite size) expansion self-assembling formation
Joint profile.
Attached figure label corresponds to title:1-periodic unit;2-printed board;3-splicing seams profile;4-extra printed board.
Specific embodiment
The present invention is described further by example below in conjunction with the accompanying drawings.
The joining method of printed board in frequency selection antenna house process of the present invention, is wanted including several as follows
Element:
According to the size and structure type of antenna house, FSS screens are divided into each submodule.
Wherein, each submodule area should be big as far as possible, and the number of submodule is more few better, to reduce the number of seam
Mesh.Submodule should be that engineering is producible, and the full-size of country's printed board hardboard processing is no more than 1200mm at present.
Further, for the size and shape of ready-portioned each submodule, periodic unit 1 in the module is determined
Number and arrangement position.
Such as the FSS screen submodules of a rectangle shown in Fig. 2, periodic unit 1 are arranged by triangle gridding, border is sawtooth
Shape splicing seams profile 3.3 geometry of submodule splicing seams profile that the splicing seams profile 3 of each submodule is adjacent thereto is complementary, spells
A complete FSS screen can be formed after connecing.What Fig. 1 was provided is the splicing schematic diagram of four submodules of above-mentioned FSS screens, submodule
Splicing seams profile 3 it is complementary, a complete surface can be formed after splicing.Corresponding FSS submodules are etched in printed board 2
Afterwards, extra printed board 4 should be removed, the laser cutting method that the processor of printed board at present uses, and can be very good to ensure processing
Precision.
