Hi,
I did recently start with my pcb design for the nRF52811, but I have some questions about the antenna. I want to use a 2450at18a100 chip antenna of Johanson Tech.
1) In the datasheet of the chip antenna there are 2 options. One with matching circuit and one without. Do I need this extra? Because the L1 en C3 are included in the reference design of the nrf52811.
2) Also did I read about a pi-network (this is used for antenna tuning I guess) do I need to implement that in my circuit?
3) Are there any other points I should keep in mind? This is my first time with RF, I don't want to miss anything.
