【摘要】 为了进一步提高微波滤波器的品质性能,增强其应用性,提出了一种新型的C型环缺陷地结构(DGS-Defected Ground Structure)单元,该单元几何图形简单,可减小滤波器尺寸。经过对C型环DGS单元带阻特性的分析仿真,得到了最佳性能的仿真模型。实验结果表明,C型环缺陷地结构单元可获得极窄的阻带(约1GHz),由C型环单元构成的滤波器Q值可达130.2。更多还原

【Abstract】 A novel C-ring defected ground structure (DGS) unit for microwave filter was proposed. The graph of DGS unit is simple, and makes the flter size reduced. The bandstop property of C-ring DGS were analysed and simulated, the simulation model with the best performance was gotten. Results show that the C-ring unit filter can get a narrow bandgap (about 1 GHz) and Q value of 130.2.更多还原
