摘　　要：为有效减小C波段基片集成波导的尺寸和插入损耗,提出了一种基于半模基片集成波导的紧凑型宽带带通滤波器。该滤波器引入由单个谐振槽和多个谐振槽组成的缺陷微带结构,并对其性能进行了研究。通过HFSS仿真验证,引入的缺陷微带结构,不仅可以减小插入损耗,而且实现传输零点的引入,改善了阻带特性。该方法设计的半模基片集成波导带通滤波器具有集成度高、体积小、成本低、制造方便等优点,在C波段卫星和雷达中得到了广泛的应用。In order to effectively reduce the size and insertion loss of the C-band substrate integrat ed waveguide,a compact broadband bandpass filter based on half-mode substrate integrated wave guide was proposed.The filter introduced a defective microstrip structure consisting of single resonant solt and multiple solts and its properties were studied.It is verified by HFSS simulation that the intro duction of defective microstrip structure can not only reduce the insertion loss,but also introduce the transmission zero point and improve the stopband characteristics.The HMSIW bandpass filter de signed by this method has the advantages of high integration,small size,low cost and convenient man ufacturing,and has been widely used in C-band satellites and radars.
