Description
Technical field
The present invention be on a kind of selectively permeable mobile phone signal, the other frequency electromagnetics of cut-off based on the ring-type cycle
The textile of structure, the preparation method of the textile and the textile are related in the application of clothes, curtain, wall body decoration thing etc.
Field of fabric producing technology.
Background technology
Mobile phone has become necessity for life in real life.Unicom, movement or the electricity of existing 2G, 3G, 4G network in China
Conveniently machine, the communication frequency of use is in 0.9~1.0GHz, 1.8~2.0GH, 2.3~2.6GHz these three frequency ranges.Except
Outside mobile communication frequency, also have it is various cannot predict, the electromagnetic wave of different frequency is full of in living space, such as 48.5~
The electromagnetic radiation of the television channel of 958MHz frequency ranges, the WLAN WLAN of 5.8GHz and other frequency bands, and this
A little electromagnetic waves more or less influence whether life or normal communication requirement.Therefore, exploitation one kind can pass through mobile communication frequency
The frequency selection transparency textile of electromagnetic wave, the other frequency electromagnetics of cut-off, has great potential application space.For example need
Electromagnetic shielding clothing is worn, is mounted with the crowd of pacemaker it is necessary to have shielding properties and does not influence mobile communication
Curtain and wall etc..
Existing Electromagnetically shielding fabrics, are generally made into using metal scribbled, or in fabric face integral plated metal
Layer obtains so that and fabric is in the range of defined wave frequency, such as 1~18GHz, has the shield effectiveness for meeting demand,
For example it is higher than 40dB.The kind fabric is more to realize that shielding it is necessary to have certain electrical conductivity, consumes one by direct reflection electromagnetic wave
Quantitative metallic fiber has certain metal coating thickness；Meanwhile for shielding wave band in electromagnetic wave, no matter any frequency
Rate, without exception reflection.In electromagnetic arts, frequency-selective surfaces as it is alternative by some frequency electromagnetics, it is another to end
The structure of a little frequency electromagnetics, important application, and the heat of research have been obtained in numerous areas such as communication, antenna, radars
Point.At present, frequency-selective surfaces are limited to rigid material more, such as in the enterprising row metal patch of rigid media or on a metal plate
Periodically perforate is formed, and is had the shortcomings that hard matter, processing difficulties, is not easy MULTILAYER COMPOSITE.Apply lintel Chinese parasol tree et al. and propose textile electricity
The Research Thinking of magnetics and electromagnetism textile development, by metallized fabrics technology, uses for reference the periodic structure of frequency-selective surfaces,
By the metallic conduction of the shape such as square, circle, Jerusalem, dipole or non-conductive medium part, periodicity battle array
Column distribution, it can be achieved that the frequency selectivity of textile material leads to thoroughly, and proposes rough in media web or conductive fabric surface etc.
Preparation for processing.Prior art discloses wave frequency selection to lead to textile and preparation method thereof thoroughly, it is proposed that substantially
Preparation method and feasible basic principle, but concrete application and design principle for frequency-selective surfaces etc., be very
Complicated problem in science.

Cardioid, combined etc., different structure shape need to be prepared using different methods, and are adapted to specific purposes, such as ring
Shape structure is not suitable for carrying out direct etching on conductive base, and real heart-shaped structure is not suitable for low-frequency resonant point etc..(2) need to count
Calculate periodic structure size.On the one hand, for some specific frequency, size corresponding to different shape there are significant difference, from
And influence practical performance；On the other hand, each structure size of periodic structure corresponds to different implications, it is impossible to arbitrarily chooses, part
It is oversized to cause graing lobe, it is too small to cause processing difficulties etc..(3) need to consider conductive base and non-conductive substrate.Base material
The difference of material, the difference of current-carrying part electrical conductivity can cause the difference of resonant frequency.(4) necessary simulation theory calculating and reality
The combination of border experience.Since the combination of structure and size and base material is ever-changing, in order to develop suitably, with particular resonance frequency
The material of point, is essential on known experiential basis, with reference to necessary theoretical calculation.Clearly for specific frequency
Selectivity it is thoroughly logical, it is necessary to based on stringent theoretical calculation and experimental verification, and select suitable periodic structure, have it is more smart
True periodic structure size and distribution, supporting suitable specific preparation method；And in application aspect, in order to ensure the cycle of structure
Property and flatness, some particular/special requirements.
