Wave-absorbing structure for UHF frequency band and communication equipment

Abstract

The invention provides a wave-absorbing structure for a UHF frequency band. The structure comprises a first plate and a second plate, wherein the first plate and the second plate are correspondingly disposed in a front-and-back manner; the first plate comprises a medium base layer and a metal layer coinciding with the center of the medium base layer; the metal layer is attached to one side of thedielectric base layer, and the dielectric base layer is larger than the metal layer; the metal layer is formed by sequentially arranging an even number of serpentine line sets at equal intervals, andthe even number of serpentine line sets are symmetrically arranged with the axis as the center; each serpentine line group comprises a section of serpentine line and a loss loading piece, wherein oneend of the loss loading piece is communicated with the serpentine wires in the group, the other end of the loss loading piece is communicated with the serpentine wires in the adjacent group, and therefore the serpentine wire groups in the metal layer are connected in series to form a loop; the second plate is a metal reflecting layer. According to the wave-absorbing structure for the UHF frequencyband, on the basis that the structural strength is guaranteed to a certain extent, electromagnetic absorbing effects with different properties are achieved. The invention also provides communicationequipment.

Description

technical field [0001] The invention belongs to the technical field of communication, and more specifically, relates to a wave-absorbing structure and communication equipment for UHF (Ultra High Frequency, UHF) frequency band. Background technique [0002] With the development and progress of society, electronic devices are used in all aspects of people's lives, such as the central control system of automobiles, mobile phone systems, personal computers, smart home systems, etc. These systems are prone to electromagnetic interference problems during use, resulting in system errors or even damage. [0003] At present, in order to avoid electromagnetic interference, most electronic devices on the market often have electromagnetic shielding structures on the devices. Although these electromagnetic wave shielding structures can isolate electromagnetic signals and prevent electromagnetic interference between different devices and systems, due to communication systems often Intric...
