摘要

本文设计了一种具有频率可重构特性的微带带通滤波器。设计的滤波器采用双模开环孔谐振器(DOHR)构成。变容二极管用作调谐元件，以调节中心频率。实验结果表明，中心频率调谐范围为2.04~2.5GHz，可用于LTE、CDMA、WLAN等网络。

A Frequency Reconfigurable Band-pass Filter Based on Microstrip Open-Loop Hole Resonator

Design of a microstrip bandpass filter (BPF) with frequency reconfigurability is presented in this paper. The designed filter is constructed by using dual-mode open-loop hole resonator (DOHR). Varactor diodes are used as tuning elements in order to adjust center frequency. The achieved results indicate a center frequency tuning range of 2.04~2.5GHz, which can be used for LTE, CDMA, WLAN, etc.
