请教pifa怎么加接地

没有人知道吗

我需要了解你的模型,把模型贴上来,我给你看看

我不了解PIFA天线和你的模型,
如果PIFA的激励端口平面与地是平行的,加一个与激励端口直径同宽,在其中心处并与前两者者垂直的矩形, 在内部加激励的用 lumped port

就是手机上用的，一般都是pifa，我的意思是指它的接地端如何建模，也用lumped port馈?

我不了解PIFA天线,你将你的模型贴上来,我一看就了解如何做了,我可没时间去了解PIFA！

兄弟，就这种样子的，看看怎么馈

Solution Type Window: Choose Driven Terminal
Assign a Perfect E boundary to the Infinite Ground (you gound)
Assign a Perfect E boundary to the top shape(your patch)
Create the Wave port for feed point(shape same as your feed point)
try it

ok！ i will try it try it, thank you！ i will tell you the result.

good luck！

kairi问题已经解决，thank you. but i used lamped port to feed. i am very surprised that when i used coax line feed there was much error notice, so i use lamped port.

问题解决了就好，这要看你应用的情况了
