I need to use the DA14580 BLE chip for my project. The problem is for the antenna. The reference design provided for the antenna is only PCB trace that's is too big for my project:
I don't know how to choose a chip antenna instead. The DA14580 need to communicate with my smartphone, as a wearable. So the distance is not really big.
I see that some device use the DA14580 with chip antenna, but I don't find any information about the antennas used for.
I think of using this chip (even if a little big) :
Do you think that will work ?
How to choose a chip antenna for BLE ?
