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.
