随着无线通信技术的发展,各种各样的射频器件变得越来越重要。文中提出了一种新型的基于开环谐振器的微带双通带滤波器。该滤波器由两个独立的开口谐振环组成,分别调节微带线和谐振器的尺寸来获得两个通带。在详细分析各参数对性能影响的基础上,设计了一款能够工作在2.45 GHz和5.7 GHz频段的滤波器。根据仿真结果制作了实物模型,结果表明测试结果和仿真曲线吻合较好,达到了预期的设计目标。
With the development of wireless communication technology, various kinds of radio frequency devices become more and more important. In this paper, a new type of microstrip double-pass filter based on open-loop resonator is proposed. The filter consists of two separate split-ring resonators, each sized to achieve two passbands. Based on a detailed analysis of the performance impact of each parameter, a filter designed to operate in the 2.45 GHz and 5.7 GHz frequency bands was designed. According to the simulation results, a physical model was made. The results show that the test results are in good agreement with the simulation curves and achieve the expected design goals.
