摘　　要：介绍了矩形波导空间功率合成技术的工作原理,利用小反射理论和谱域法原理,结合微波仿真软件,对渐变鳍线过渡电路进行了优化设计,使工作频率带宽和合成效率得到了有效提高。在X波段实现了双对极鳍线的空间功率合成系统,在相对带宽大于25%的宽带范围内得到的合成效率大于70%,输出功率大于25 W。The working principle of the spatial power combining technology for the rectangular waveguide is introduced. Based on the theory of small reflections and the spectral domain approach（ SDA）,the tapered fin-line transition circuit is optimized through the microwave simulation software,which effectively improves the bandwidth of the working frequency and the combining efficiency. The spatial power combining system of the double antipodal fin-line is realized at X band. The results show that within the relative bandwidth of more than 25%,the combining efficiency is over70% and the output power is more than 25 W.
