1. 毕业设计(论文)主要目标:
本论文研究的是一种带有两个梳状金属片的共面波导(CPW)馈电的槽形偶极天线。天线能在五个频段实现谐振(回波损耗大于10 dB),并在每个工作频段中皆实现大于5.3 dB的增益,同时实现H面的全向辐射。
2. 毕业设计(论文)主要内容:
仿真一种带有两个梳状金属片的五频带共面波导(CPW)馈电槽偶极天线。每个操作频段由相应的路径控制,五个频段分别为1.88(f1),2.34(f2),2.70(f3),3.08(f4)和3.60 GHz(f5),相对带宽分别为17.68%,8.66%,5.59%,11.61%和5.27%,每个频带可实现独立调节,以便用于商业无线通信系统。
