Problems solved by technology

At present, there have been researches on applying FSS to 5G signal transmission, but the research mainly focuses on single-band research, which cannot meet the development trend of multi-band transmission today.
In addition, the existing FSS structure applied to the 5G frequency band also has the problem of poor stability, resulting in poor filtering characteristics of the structure, and the existing FSS structure unit size applied to the 5G frequency band is large, which does not meet the current pursuit of miniaturization Structural Trends and Needs

Abstract

The invention relates to a frequency selection surface structure applied to 5G communication and a unit structure thereof. The unit structure comprises a first dielectric substrate, a metal layer anda second dielectric substrate which are arranged in order from top to bottom, wherein the metal layer is provided with an improved Jerusalem gap and an improved square-ring gap; the improved square-ring gap surrounds the periphery of the improved Jerusalem gap, and the center of the improved Jerusalem gap and the center of the improved square-ring gap coincide with the center of the metal layer. The frequency selection surface structure comprises M*N periodically arranged unit structures. The frequency selection surface structure comprises dual-band band-pass features of 28GHz and 39GHz, and agood filtering effect; and moreover, the frequency selection surface structure has excellent polarization stability and angle stability, and when incident waves are incident at different angles in different polarization modes, the resonance frequency is always within a 5G frequency band.

Description

Technical field [0001] The invention belongs to the field of wireless communication technology, and specifically relates to a frequency selective surface structure and its unit structure applied to 5G communication. Background technique [0002] The frequency selective surface (FSS) is a kind of spatial electromagnetic filtering structure, which can make the electromagnetic wave pass without loss or low loss in a specific frequency band, and the electromagnetic wave outside the frequency band can be filtered out. FSS is essentially a periodic surface composed of a specific unit structure in a specific arrangement order, which can exhibit total reflection or total transmission characteristics in a specific frequency band, which is equivalent to the role of a spatial filter. FSS can be applied to the radome, by loading the frequency selection surface, the radar cross section can be reduced to achieve the stealth effect. In addition, by applying FSS to the absorbing material, minia...
