摘要
介绍了一种新型的具有分形特征的宽带 AMC 结构。这种结构是将普通 AMC 结构贴片的边缘用 Minkowski 环代替形成,结果发现使用这种结构可以得到更宽频带的电磁带隙。在3GHz 左右的频率,电磁带隙宽度可提高28%左右。这种结构可用于实际的宽带电路和天线中。
In this paper, a novel fractal AMC structure is introduced. This structure is formed by replacing the edges of normal AMC structure with Minkowski loop. And broad band characteristic of electromagnetic band gap is achieved. The results show that the bandwidth of band gap is increased about 28% at 3 GHz. This structure can be utilized to wide band antennas and circuits.
