这项工作描述了二维准光功率组合阵列原型的设计理念和实验结果。使用几种不同的准光电路来获取本研究的基本数据。使用大信号分析解决了如何将天线输入阻抗合并到有源天线电路中以及如何分析两种工作模式下的强耦合条件。演示了几种电路配置，包括工作在 9.3 和 24.0 GHz 的单个有源天线、工作在 15.6 GHz 的六元件线性功率组合阵列以及工作在 10.4 和 7.8 GHz 的四元件和十六元件二维功率组合阵列。讨论了天线方向图和调谐范围等重要特性。讨论了二维单片准光功率组合阵列的前景。 >
This work describes the design concept and experimental results for prototypes of two-dimensional quasi-optical power-combining arrays. Several different quasi-optical circuits were used to obtain the fundamental data for this study. How to incorporate the antenna input impedance into the active antenna circuit and how to analyze the strong coupling condition with two operating modes are addressed using large-signal analysis. Several circuit configurations are demonstrated, including a single active antenna operating at 9.3 and 24.0 GHz, a six-element linear power-combining array operating at 15.6 GHz, and four-element and sixteen-element two-dimensional power combining arrays operating at 10.4 and 7.8 GHz. Important characteristics such as antenna patterns and tuning ranges are discussed. The prospects for a two-dimensional monolithic quasi-optical power-combining array are discussed. >
