摘要
按照传统方法设计了一个截止频率为3 GHz,通带波纹不大于0.5 dB。利用缺陷地单元(DGS)的带阻特性对传统设计方法进行了改进,改进后的滤波器完全满足设计要求,并使滤波器尺寸大幅减小。
In this paper the author designs a conventional microstrip low-pass filter with a 3 dB cutoff frequency of 3 GHz and a passband insert-loss less than 0.5 dB.The filter is improved by defected ground structure.The proposed filter has the same parameter but has smaller size.
