摘要 采用小波反射理论分析Klopfenstein结构的鳍状天线阵的传播特性，设计优化出应用于空间功率合成模块的输入输出鳍状天线阵，优化后的鳍状天线阵不仅表现出宽频带特性而且还有比较好的回波特性，可以有效地提高功率合成模块的效率，2＊2鳍线阵在端接120Ω负载时的实测结果为：在C波段（3～4．9GHz）内回波损耗大于20dB，驻波比小于1．25，本文是国内第一篇详细介绍鳍状天线阵的设计和优化的文章，该项研究填补了我国在相关领域中的研究空白。 The propagation characteristic of Klopfenstein taped finline array was analyzed by using the theory of small reflections. As a result, the input and output optimal finline array for spatial power combiner was obtained. The finline array has the broadband characteristics and the better return loss, which will directly enhance the combiner efficiency. When the 2 ＊ 2 finline array was terminated with 120Ω chip resistor, the return loss is better than 20dB and the VSWR is less than 1.25 for the entire C-band（3-4.9GHz）. It is first time in China that the designs and optimiztion of the finline array are described in detail.
