In this case should I also select this plane as a negative port pin as well? However, I do also get a ground plane underneath of this line. Based on the impedance calculation, the RF feeder width is calculate as considering it as a CPW. I am also bit not clear on applying discrete port positive and negative port pin definitions.
In this case should I draw a one big ground plane with the same size as the circuit? I have attached an image of the actual top layer and bottom(Blue - Ground) layer PCB design.Īs you can see, the blue color ground plane is not completely a plane. Is it ok to add the entire ground plane and then add matching network separately?
What I wanted is to do a simulation on just the antenna section and then add separate lumped element matching network so that I can match with the impedance of the nRF chip ANT port.
