摘要
采用齿化边缘技术对普通的人工磁导体(AMCArtificialMagneticConductor)结构进行了改进,可以获得更宽频带的电磁带隙。仿真结果表明,在带隙中心频率为7GHz左右时,带隙宽度提高了240MHz,比普通结构提高了15%左右。制作了实际的电路,测量结果与仿真结果基本一致。
An improved AMC （Artificial Magnetic Conductor） structure with patch sides inserted by small slots is introduced in this paper. For this novel improved AMC structure, a wide-band EBG （Electromagnetic Band Gap） can be achieved. At about 7GHz, the simulated results show that the band width of band gap is increased by 240MHz （about 15%） comparing with the conventional AMC structure. Practical circuits are fabricated, and the measured results agree with that simulated well.
