为了实现高功率微波的多路等幅同相功率分配, 提出了一种新型的使用单圈探针耦合的多路径向线功率分配器。通过对新型探针耦合特性的分析, 设计了一个S波段的16路功率分配器模型, 并对该模型进行了数值模拟和实验测量。实验结果表明：该功率分配器在2.55~3.15 GHz的频带范围内, 驻波比小于14, 插入损耗小于0.3 dB, 输出幅度不平衡度小于±0.5 dB, 输出相位不平衡度小于±5°, 可以在较宽的频带内实现微波的等幅同相功率分配。

A novel radial line power divider using single-circled probe coupling is proposed to realize the equal-amplitude in-phase multiport power division of the high power microwave. An S-band 16-port power divider is designed by analyzing the coupling characteristics of the new probe. Numerical simulation and experimental measurement are conducted for the power divider. The experiment result shows that in the frequency range of 2.55 to 3.15 GHz, the voltage standing wave ratio (VSWR) is below 1.4, the insertion loss is below 0.3 dB, the amplitude imbalance is within ±0.5 dB, and the phase imbalance is within ±5°, which proves that the power divider can realize the equal-amplitude in-phase power division over a wide frequency range．
