[SI-LIST]

Hi, all,
I am working on an antenna.

I met a problem as below:

At the connector, there are three signals:

ANT: antenna signal (50R)

ANT_GND: antenna ground

GND: the whole PCB ground

Which ground plane should be the reference ground plane for the 50R
impedance calculation?

My PCB is 8 layers. The mirror area of the reference ground on all
layers should be the reference ground plane, yes or not?

 

Best regards

Linda Tang
