微带天线讨论摘要 通信系统得进展带来了天线行业得勃勃生机,在众多得天线类型中微带天线已成为当前讨论得前沿之一,很具有讨论前景与有用意义。特别就是微带缝隙天线,以其重量轻、剖面薄、平面结构且易与载体共形,馈电网络可与天线结构一起制成等优点已经引起天线工作者得广泛关注。本文简要介绍了微带天线与微带缝隙天线得分类、分析方法、主要参数,然后提出了一种三角形缝隙微带天线。在介质基板得一面一个三角形缝隙,另一面采纳一个等腰三角形微带线进行馈电。通过仿真给出了天线得 s 参数,VSWR 与方向图。 关键词:天线参数,微带天线,微带缝隙天线,三角形缝隙微带天线设计 目录 一、绪论···································································· 31、1 简介······································································31、2 微带天线得进展····························································31、3 微带天线得特点···························································3二、微带天线基本知识·························································42、1 微带天线得辐射机理························································4 2、2 微带天线得分析方法························································42、3 微带天线得主要电参数··························· ··························5 2、3、1 输入导纳·····························································5 2、3、2 辐射电阻与品质因数··················································5 2、3、3 带宽····················...
