【摘要】 滤波器是微波毫米波电路与系统中一个重要的部件。提出了一种CMRC加载基片集成波导(substrate integrated waveguide,SI W)滤波器。该滤波器具有体积小、重量轻、容易加工和集成等优点。滤波器的中心频率为5.3GHz,相对带宽为36%,中心频率处的插入损耗为1.5dB,仿真与实验结果吻合良好。更多还原

【Abstract】 A bandpass substrate integrated waveguide(SIW)filter based on compact microstrip resonating cells(CMRC)was proposed.Featuring high Q factor,high power capacity and small size,this filter has a center frequency of 5.3 GHz,and a fractional bandpass width of 36%,and its insertion loss at central frequency is less than 1.5 dB.Results from numerical simulation are in good agreement with experimental results.更多还原
