结构紧凑的微带低通滤波器

一种结构紧凑的微带低通滤波器

内容简介：本文以一截止频率为5GHz、终端开路短截线型的微带低通滤波器为原型。通过合理的结构改进，将该传统结构的滤波器变换成一种结构紧凑，性能优良的新型低通滤波器。通过试验验证，该新型结构滤波器不仅比传统的滤波器长度减小3.2倍，同时还表现出良好的滤波特性。在小型化电路中，该结构的滤波器非常具有实用价值。

Abstract： A compact,novel lowpass filter with good characteristic is proposed in the paper.This filter is improved reasonablely based on a microstrip lowpass filter using Open-Circuited Stubs,whose cutof frequency is 5GHz.According to the results of experiment,the novel filter shows excel ent filtering characteristic,and it reduces 3.2 times in length as wel .The filter can be very useful in the circuit with smal size.
