摘要

本文采用带电容耦合谐振器的带通滤波器结构，实现了在UHF低频工作的印刷滤波器。该滤波器工作在380兆赫的中心频率，带宽为18%，宽3db。滤光片的形状为正方形，其边缘长度小于波长的十一分之一。详细介绍了滤波器的设计过程。测量结果和预测结果非常吻合。

A new microstrip band-pass filter for UHF range

In this paper a printed filter operating at low end of UHF range is realized by implementation of a band-pass filters configuration with capacitive coupled resonators. The filter operates at central frequency of 380 MHz with 18% wide 3 dB bandwidth. The filter has a shape of a square with the edge length smaller than one eleventh of the wavelength. Filter's design process is described in detail. Measured and predicted results are in very good agreement.
