微带天线设计求助

05-08

大虾,在设计微带天线时,当用微带线馈线时,微带线的长度怎么取呀?传输的是TM10模.偶是新手,请大家帮忙了!

微带馈线的长度一般取1/4波长左右,这只是个大概值,如果
你天线的输入阻抗和馈线的特征阻抗匹配的很好,例如反射系数在30DB以下,
馈线的长度对仿真结果影响很小,但如果你匹配的不好,这个影响就大了,
实际仿真时,如果你最终要做一个天线阵,应考虑在构成阵列时,阵元间距一般都大于1/2波长小于1个波长,根据这个适当选取馈线长度;如果你只是做天线单元,实际应考虑,天线的安装尺寸要求。

多谢2楼的,我把模型发给你,帮我看看可以吗

可以,你传上来吧

我谢2楼的,我另发了帖子,在"微带天线求救啊"的哪个栏目中,给了详细的参数.谢谢谢谢你!
