sir,在使用chip antenna (型号:FR05-S1-N-0-102)时,请问两个脚(一边丝印是正方形,一边丝印是圆形)的属性是一样的吗?没有方向之分吧?我只需一个脚连接信号,另一个脚悬空?
应该是有区别的。你可以看下以下关于介绍这个天线的文档

里面有一段话
The white rectangle located on the front side of the antenna provides you with a visual cue to mount the antenna. It is located physically above the feed point of the antenna and has been included to reduce probability of manufacturing error.
VV,你好,这段话的意思只是指导制造厂焊接方向,并没有说哪个脚是具有哪个电气属性,我现在设计遇到的问题是不知道两个脚的电气属性,还请帮忙再check,谢谢
