Broadband electromagnetic transparent enhancement device

Abstract

The invention discloses a broadband electromagnetic transparent enhancement device, which comprises a weak electromagnetic transparent material, a first electromagnetic anti-reflection plate, a second electromagnetic anti-reflection plate and glue. The first and second electromagnetic anti-reflection plates are respectively provided with the same size of air holes at an equal interval for adjusting equivalent dielectric constants, the material used for the second electromagnetic anti-reflection plate and the air hole size and arrangement of the second electromagnetic anti-reflection plate are different from that of the first electromagnetic anti-reflection plate. The first electromagnetic anti-reflection plate is pasted on the front surface of the weak electromagnetic material by the glue, and the second electromagnetic anti-reflection plate is pasted on the reverse surface of the weak electromagnetic material by the glue. After the first and second electromagnetic anti-reflection plates are loaded on the weak electromagnetic transparent material, the weak electromagnetic transparent material greatly increases the intensity of the electromagnetic signal transmission in the wider frequency band and enhances the electromagnetic signal transmission. According to the weak electromagnetic transparent material with different materials and the working frequency band thereof, the anti-reflection plates of different thicknesses and different dielectric constants can be properly selected, the material selection is convenient, the manufacturing is simple and the cost is low.

Description

technical field [0001] The invention belongs to the field of microwave and millimeter wave electromagnetic communication, and relates to an electromagnetic transparency enhancing device. Background technique [0002] With the rapid development of modern communications, the 5G era is coming. In order to obtain greater communication capacity and speed, the communication frequency band has been increased to the millimeter wave band. However, the glass curtain walls of high-rise buildings in modern cities have a great loss of communication signals, which limits the distance and quality of communication. In addition, in applications such as through-wall radar detection and imaging systems, a higher electromagnetic signal transmittance can obtain a greater receiving signal-to-noise ratio and better detection results. Therefore, the improved design of broadband electromagnetic transparency enhancement devices is a hot spot in the scientific and industrial circles. [0003] In ord...

Problems solved by technology

It's just that the design structure is complex and the processing is complicated. In addition, due to the introduction of the metal frequency selective surface, additional loss is inevitably added, and this metal loss will be more serious in the millimeter wave band.

In addition, the narrow-band characteristics due to the resonant characteristics of the metal frequency selective surface are also unavoidable.
