摘要
随着毫米波技术的快速发展,八毫米波以及三毫米波器件产品相继被研制出来,并已应用到实际工程项目中。在此基础上,对两毫米波技术的应用需求也愈加迫切,两毫米波器件的研究也愈加被重视。本文通过HFSS仿真与设计软件,采用了有限元算法(Finite Element Method),完成了一种两毫米波矩形波导带通滤波器的仿真优化设计。该滤波器采用一种平行于矩形波导端口面的膜片分腔结构,形成了一种特殊的波导腔体谐振式选频网络。实现了中心频率为140GHz,带宽为8GHz,插入损耗小于0.1dB,回波损耗大于25dB,带外抑制为-20dB左右的技术指标。
With the rapid development of millimeter wave technology,8 millimeter and 3 millimeter wave devices have been developed,and has been applied to practical engineering projects.At the same time, the application demand of 2 millimeter wave technology is more and more urgent, the research of 2 millimeter wave devices are increasingly being attention. In this paper,through the HFSS simulation and design software,using the finite element method (Finite Element Method),completed a two millimeter wave rectangular waveguide bandpass filter design. The filter has adopted the diaphragm chamber structure,which is in parallel with the rectangular waveguide port,realizes a kind of special cavity resonant frequency selective network.The center frequency of bandpass filter is 140GHz,with 10GHz band-width and 0.1dB insertion loss and about 25dB attenuation in the band and -20dB outside the band.
