| 摘 要： | 在综合分析了微带平面天线阵列馈电网络的两种传统馈电方式的基础上,提出了一种在微波工程应用中实际使用的一种新型馈电网络,提高学生理论知识与实践相结合的能力,更好的掌握最新技术发展。其新型馈电网络由一种左-右手混合微带传输线构成,可以获得高于传统并联馈电网络的天线阵列增益;同时,可以修正传统串联馈电网络的天线阵列辐射方向图的波束偏移,给出了一个工作频率为35GHz的2×2微带面阵的馈电网络设计案例,验证了其理论的正确性。

| Abstract: | A novel feeding network with composite right/left-handed transmission line(CRLH-TL) for 2-dimension millimeter wave microstrip patch arrays is proposed.Because of the simpler structure and the shorter length of the CRLH-TL feeding network,the antenna array is of higher gain than that with the parallel feed network.Besides,the radiation pattern shift resulting from the traditional parallel-series feeding network is removed since no inserting phases shift are introduced in the patch elements using the novel f... |
