Abstract
The invention discloses a kind of transparent combined glass of wideband electromagnetic, including glass, first medium composite plate, second medium composite plate and the viscose for fixing.First medium composite plate is laminated by the material of M layer differing dielectric constants, and every layer of thickness is intends a quarter by wavelength, by viscose Surface Mount in glass front.Second medium composite plate is laminated by the material of N layer differing dielectric constants, per thickness degree also to intend a quarter by wavelength, by viscose Surface Mount in glass reverse side.Loss of the glass to electromagnetic signal in the range of broad frequency band after loaded medium composite plate has great reduction, and then realizes that electromagnetic signal low-loss passes through.The present invention can be used for glass curtain wall, for improving indoor signal strength, improve communication quality, its advantage is, the composite plate of different-thickness differing dielectric constant can be appropriately selected according to unlike material glass, and lighting performance is had little to no effect while magnetic particles are improved, it has wide range of applications, it is convenient that composite board material is chosen, and cost is relatively low.
Description
Technical field
The invention belongs to microwave and millimeter wave electromagnetic communication field, is related to a kind of electromagnetic transparent combined glass.
Background technology
In Modernized City Construction, for good daylighting, substantial amounts of glass curtain wall, glass door and window are applied to house and built
In if.With the high speed development of modern communicationses, the 5G epoch at hand, in order to obtain bigger message capacity and speed, communicate
Frequency range has brought up to millimere-wave band.But loss of the glass to communication signal is very big, the distance and quality of communication are limited.Cause
This, the Curve guide impeller of the transparent glass for building purposes of wideband electromagnetic is a big focus of scientific circles and industrial quarters.
Devise to reduce loss, Karlsson et al. of the glass for building purposes to incident electromagnetic wave signal and a kind of be based on glass
The frequency-selective surfaces of glass improve communication quality (A.Karlsson, B.Widenburg, " the Design of inside and outside room
Frequency Selective Windows for Improved Indoor Outdoor Communication ",
Transactions on Antennas and Propagation, IEEE, vol.54, pp.1897-1900,2006), pass through
Metal oxide layer on energy-saving glass surface etches corresponding frequency-selective surfaces structure, is formed in 900MHz-2GHz frequency ranges
Electromagnetism passband, reduce the influence to signal of communication, effect is lifted in more than 10dB to the transmitance of electromagnetic wave.Simply design
Can apply to energy-saving glass, for other non-energy-saving glass and do not apply to, application is very limited, and the design can only compared with
Low communication frequency range has good effect, in millimere-wave band, because glass is from height loss characteristic, result in frequency-selective surfaces and sets
Meter analysis is more complicated, and extra metal loss is larger, effect and unobvious.
The content of the invention
It is an object of the invention to overcome above-mentioned the shortcomings of the prior art, there is provided a kind of width of transparent dielectric layer loading
Combined glass with electromagnetic transparent, on the premise of glass transmission is ensured, while realize the high-permeability of electromagnetic signal.

Plywood is by viscose Surface Mount in the front of glass；The second medium composite plate by viscose Surface Mount glass reverse side.
Further, the first medium composite plate by M layers (M is positive integer) dielectric constant it is different material stacking and
Into, a quarter for the electromagnetic wave medium wavelength that the thickness per layer of material passes through for plan, the dielectric constant values per layer of material
Between application environment medium permittivity value and glass dielectric constant value, and the outside list near one layer of glass
Modulation.
Further, the second medium composite plate by N layers (N is positive integer) dielectric constant it is different material stacking and
Into, per layer of material dielectric constant values between application environment medium permittivity value and glass dielectric constant value, and
The outside monotone variation near one layer of glass.Number of layers N and first medium composite plate in second medium composite plate
In number of layers M values can be different.
Further, the frame size of described first medium composite plate and second medium composite plate is less than or equal to glass

The present invention compared with prior art, has advantages below and beneficial effect：
(1) first medium composite plate and second medium composite plate of the present invention, there is extremely low loss, to electricity
Magnetic signal by having little to no effect；Its thickness is only a quarter of electromagnetic wave operation wavelength simultaneously, in 5G communications bands
With very small section size, therefore to the influence very little of the overall appearance property of glass.
(2) first medium composite plate and second medium composite plate of the present invention, its dielectric constant can be by answering
It is calculated with environment medium permittivity value and glass dielectric constant value, one layer of either multilayer acoustical panel can be used to fold
Add realization, material selection scope is wider, with design is simple, cost is relatively low, short preparation period advantage；
(3) present invention can by change first medium composite plate and the second medium composite plate of different structure size come
The light electromagnetic signal transparent characteristic in different frequency range for realizing different glass, its application scenario are quite varied.
The purpose of the present invention, feature and advantage will make explanation further below referring to the drawings in conjunction with the embodiments.
