摘要
Abstract
A 2.4 GHz and 5 GHz dual-band electromagnetic absorber structure based on Dual Split-Ring Resonator is designed for the WLAN band of laptops.The absorber structure consists of three parts:metal resonant layer,dielectric layer and metal reflective layer.The metal resonant layer unit realizes the miniaturization and dual-band characteristics of the absorber by using two embedded curved Split-Ring Resonator structures.The simulation results show that the peak absorption rates of the absorber structure at 2.42 GHz and 5.2 GHz resonant frequencies can reach 97%and 98%,respectively.Moreover,the structure of the metal resonant unit of the absorber is simple,and the resonant frequency of the absorber can be adjusted by adjusting the structural parameters of the resonant unit.This design provides a reference for the subsequent design of electromagnetic absorbers for the WLAN band of laptops.关键词
