采用自谐振膜片和短路支节设计的波导滤波器

摘要

致力于小型化微波波导滤波器技术的研究和设计.对自谐振膜片和短路支节进行研究,包括膜片开孔的长、宽、高对于膜片的谐振频率的影响和支节的长、宽、高对于零点频率的影响.进而设计了一款小型化,高频率选择性的滤波器.%The purpose of thisthesis is to study and design new compact waveguide filters with these characteristics, A systemic research of resonator-irises and waveguide E-plane shorting stubs will be done. It consists of the relationship between the resonance frequency and the dimension of the resonator-irises and the relationship between the transmission zero frequency and the dimension of the shorting stub. Then a new compact waveguide filters with these characteristics is studed and designed.
