| 摘 要： | 提出了具有非周期分形形状的缺陷地结构(DGS)低通滤波器,仿真结果表明,与传统的周期DGS相比,新型的DGS单元晶格非周期设计可以产生较好的通带和较宽的阻带.为了验证所提出方法的有效性,设计、加工、测量了这种非周期分形缺陷地结构低通滤波器.结果表明,通带内反射损耗最大值为-24dB,而且阻带也展宽到6 GHz.

| Abstract: | A novel non-periodic defected ground structure(DGS) for low-pass filter using Koch fractal are proposed.Simulation shows that it is different from the periodic DGS in that the non-periodic unit lattices of new DGS can have obtained passband and enlarged stopband bandwidth.The designed non-periodic fractal-shape DGS of LPF is processed and measured to verify its validity.Results show that the maximal return loss sidelobe level is-24 dB and that the stopband width is 6 GHz. |
