高度定向矩形贴片天线阵列

G.Jeevagan Navukarasu Lenin, J.Anis Noora, D.Packiyalakshmi3, S.Priyatharshini4,T。摘要:本文介绍了适用于无线通信应用的微带阵列天线的各种设计。特别对4x1 2x1和单单元矩形几何进行了设计和仿真。增益和指向性可以通过增加阵列元素的数量来增强，但以旁瓣电平为代价。采用聚四氟乙烯基板可以提高增益和回波损耗性能。四分之一波变压器用来给元件供电。对该方案进行了数值研究，并利用ads2011软件进行了仿真。并对制造的原型进行了实验测试，结果与理论预测相吻合。结果表明，几种设计的微带阵列天线的回波损耗、指向性和增益的模拟结果符合得很好。设计的天线阵列最适合ISM频段和WLAN应用。
