Structure for improving oblique incidence characteristic of glass material in 5G millimeter wave frequency band

Abstract

The invention discloses a structure for improving the oblique incidence characteristic of a glass material in a 5G millimeter wave frequency band, and the structure comprises a transparent material film layer and a glass layer; the transparent material film layer comprises a first circuit layer, a transparent dielectric layer and a second circuit layer; the first circuit layer and the second circuit layer are printed on the upper surface and the lower surface of the transparent dielectric layer respectively, and the glass layer is located below the second circuit layer. By adhering the transparent film with the circuit on the surface to the glass, the oblique incidence transmission performance of the glass in the 5G communication millimeter wave communication frequency band can be enhanced, incident electromagnetic waves outside the transmission frequency band can be blocked, and the spatial filtering function is achieved. The structure has the advantages that: the light transmittanceis good, and the film and the circuit are subjected to transparent treatment, so the influence on the light transmittance of the glass is reduced; the use is simple, the designed film is pasted on theglass, and the operation is convenient; the loss is small: generally, the film is made of a low-loss material, so the loss in a medium is reduced.

Description

technical field [0001] The invention relates to the field of microwave communication, in particular to a structure for improving the oblique incidence characteristics of glass materials in the 5G millimeter wave frequency band. Background technique [0002] Compared with the fourth-generation mobile communication technology, the fifth-generation mobile communication (5G) technology will be greatly improved in terms of speed, delay, number of connections and mobility, especially in the 5G millimeter wave communication frequency band with better speed performance. However, due to the decrease in wavelength due to the increase in frequency, many effects that are not considered in the sub6G frequency band cannot be simply ignored, such as the reflection characteristics and transmission loss when electromagnetic waves penetrate walls, windows and other dielectric layers, and the various electromagnetic signals that exist in space. interference.

However, due to the decrease in wavelength due to the increase in frequency, many effects that are not considered in the sub6G frequency band cannot be simply ignored, such as the reflection characteristics and transmission loss when electromagnetic waves penetrate walls, windows and other dielectric layers, and the various electromagnetic signals that exist in space. interference

[0003] Existing technologies usually only consider optimizing 5G millimeter-wave signal coverage and signal processing from the perspective of terminal equipment, such as the network deployment optimization scheme based on LSAA (Large Antenna Array) (“Radio propagation and wireless coverage of LSAA-based 5G millimeter-wave mobile communication systems” Haiming Wang, Peize Zhang, Jing Li, Xiaohu You), or multiple-input multiple-output communication signal processing technology based on MIMO theory (“An Overview of Signal Processing Techniques for MillimeterWave MIMO Systems” Robert W. Heath, Nuria González- Prelcic, Sundeep Rangan, WonilRoh, Akbar M. Sayeed), but did not consider reducing the loss through the medium during the transmission of electromagnetic waves, which is also the purpose of this aspect
