Hello,
I'm trying to develop a small module based around the nrf52832 chip, and I am trying to replicate the reference design and layout as closely as possible. One problem I found is the development of the rf (and specifically the antenna) part, as, from what I understand, the reference layout cannot help me as pcb substrate determines the matching of the antenna, and with it the matching L and C and geometrical dimensions change.
As for time constraints I would really need the module to work correctly (and with decent range) the first time, I wanted to ask what was the best option for my antenna and matching network - I thought using an sma connector would have been the easier thing but could not find any reference on how to design my board with it.
Would using a pcb antenna or a ceramic one be the simplest option? Where can I learn how to correctly design the impedence matching part (I took a uni course in rf some time ago so I know some of the basic theory but would have to learn how to apply it in practice)? Is there a reference I can use for designing a simple solution (will be using a 4 layer pcb from a common Chinese fabrication house)?
