中文摘要：

提出了一种新型的周期结构双频微带带通滤波器（BPF——Bandpass filter），该结构由刻蚀在补偿微带线微带两边的两个不同周期结构构成，在3．72GHz和6．01GHz频率范围内获得了两个通带，该滤波器具有低的插入损耗、紧凑的结构和好的选择性，仿真结果和实验结果符合较好。

英文摘要：

A novel dual-band microstrip bandpass filter （BPF） based on periodic structures is proposed. This structure is fabricated with two different periodic structures etched on both edges of the compensated microstrip line and two bandpasss in the range of 3.72 GHz and 6.01 GHz can be obtained. The filter has the advantages of low insertion loss, compact size, and good selectivity. The simulated and measured results are presented and show good agreements.
