摘　　要：给出了基于商用软件HFSS和最小二乘相结合的优化分析方法,设计一种新颖的管状低通滤波器,其设计思想来源于糖葫芦式同轴线低通滤波器,但与糖葫芦式同轴线低通滤波器相比,该文介绍的滤波器具有制造简单,体积小,便于调试等特点。并给出了一个管状低通滤波器的设计实例,测量结果与理论计算值吻合,验证了设计方法的可行性。In this paper, we propose a method which combines HFSS software with the least-square method to design a new tubular lowpass filter, based on traditional waffle-iron lowpass filter. Compared with the waffle-iron filter, the tubular filter with compact volume is easy to manufacture and to tune. A practical tubular lowpass filter is given. The result of experiment is consistent with that of theoretical simulation, which verifies the feasibility of the method.
