PIFA天线原理讲解
baidu搜下都有啊
线天线顶端加载——ILA——IFA——PIFA。仅此而已。
PIFA天线的增益一般能做到多大啊?
最近下了一些资料看看,稍微有点眉目,相比于普通的微带天线,PIFA天线能实现更小的尺寸。
就是微带天线的延伸;也可以看成倒L天线的发展
其增益在介质损耗角不大时利用4Pi除立体角得到
PIFA是顶加载单极子的变形,通过在辐射单元上开槽、增加短路销钉等方法,可以改变电流分布和调整匹配,获得宽带、多频等特性,因此形态各异、变种繁多。
谢谢各位的指点,使我对PIFA天线的认识更深入,更全面!
看不到资料啊

Two books introduced this type of antennas.
Braodband Plate Antennas published by Wiley & Sons
Antennas for Portable Devices published by Wiley & Sons
the most classic paper was published in 1960s by Prof. King.
any more question?
小编去下点这方面的资料吧。
one paper published in MOTL in early 2000s discussed this with experimental results.
谢谢小编分享···

手机天线采用的挺多
怎么看不到呀
