| 摘 要： | 以探索更多单元数的三角形栅格径向线子阵馈电系统为目的,对92单元子阵馈电系统进行了研究,提出了一种新型耦合探针,以满足馈电系统对耦合量及幅频特性的要求。对馈电系统微波能量不均匀分布引起的探针难以实现耦合量的等幅输出问题进行了分析,并给出了相应的解决方案。实验测试结果表明:馈电系统在中心频率2.856GHz处,驻波系数为1.1,各探针耦合量实现了近似等幅馈电;在2.76~2.92GHz带宽范围内,驻波系数小于1.5,各输出端口的幅频特性一致性较好。实验测试结果与仿真设计结果基本相符。

| Abstract: | In order to explore more elements of triangle-grid subarray radial-line feed network, research is carried out on the 92-element subarray feed network, and a new coupling probe is designed, which can satisfy the required coupling amount and amplitude-frequency characteristics of feed network. The problem that the equal amplitude outputs of coupling amount is difficult to achieve, which is caused by the non-uniform energy in the feed network, is analyzed and solved. Experiment result indicates that: At the central frequency of 2.856, the VSWR is 1.1, the amplitude-frequency characteristics consistency of feed network output ports is good; In the frequency range of 2.76-2.92 GHz subarray, the VSWR is less than 1.5, and the amplitude-frequency characteristics of each output port is basically consistent. The experimental results are basically consistent with those of the simulation. |
