摘　　要：在介绍双轴同轴型谐振微波介质滤波器结构及工作原理基础上,利用理论公式计算与HFSS10.0三维有限元仿真的混合设计方法,设计了满足性能要求(插入损耗为–3dB以上;–3dB带宽为18MHz以上)的微波介质滤波器。滤波器试样实际测试结果表明,该设计方法正确可行,测试结果与仿真结果有很好的一致性,最终设计出的滤波器插入损耗为–2.83dB,–3dB带宽为35MHz。The structure and operational principle of double coaxial microwave dielectric filter were introduced. The filter which can meet the property requirements （insertion loss was more than - 3 dB and - 3 dB bandwidth was more than 18 MHz） was designed by theoretical formulae and three dimensional finite element simulation with HFSS 10.0. The testing results show that the mixed design method is correct and feasible, and the simulated results is consistent with the pratical test results of filter sample, The final property paramerters of designed filter are as follows： insertion loss more is - 2.83 dB and - 3 dB bandwidth is 35 MHz.
