Why NFC antenna designed by NXP for their NFC chips as below . As you can see there are square planes in the middle of antenna,these planes have no Nets(does not connected to any where ). Does any one here has any idea whats function of these planes

We had been test there's no influece for magnetic field. Is there aang particular reason for the "square planes"

communication?

Hello Lu,

In fact, these square planes are metal, used to simulate the antenna working in a metal environment, your products can not need these square planes.

Have a nice day!
