leakyantenna
- 本文介绍了一种基于复合右/左手（composite right/left-handed，CRLH）超材料的新型高增益的有源漏波天线(leaky-wave antenna，LWA)。这种天线工作在边射，由无源CRLH漏波部分与放大器相互连接,重新组成一种在辐射过程中逐步增大功率泄漏的结构,从而提高天线的有效口径进而提高其增益。通过放大器的准单向特性而导致的匹配再生功能,增益还可以进一步得到提高。-This paper presents a composite based on the right

- 本文给出了一种利用幅相加权对阵列天线进行全局优化的方法。为了使天线的辐射波束形成给定的 方向图，采用联合应用DFP和BFGS公式的变度量算法对阵列天线各单元的馈电幅度和相位分布进行优化， 通过C++语言编程计算实现，从而使得优化后的阵列天线主波束形状能够与预给波束形状相吻合，达到设计 要求。全局优化是本文的特色，它弥补了局部优化结果的精确度依赖于初始值的缺点，因而得以保证通过优 化得到的天线主波束与给定波束的主瓣相吻合，副瓣也得到有效控制。该方法具有快速收敛，计算量小等优 点
