I'm really new to this filed and don't know anything about antenna, please forget me if the question is stupid.
I have an nRF52 DK, I noticed the Bluetooth antenna on it is PCB antenna, so my question is
1) if I have to design my own, will it be hard or I can do the same on the development board?
2) or keep the same circuit design in the development board, but add an attached antenna, what specifications should I follow to pick the antenna?
And I know the NFC antenna on nRF 52 DK is not commercialized, so how do I find a replacement?
(we want to use NFC to do some cellphone authentication, like between a cellphone and nRF52, so the distance will be close, like 3-5cm, but inside a plastic enclosure)
Any suggestion will be helpful.

Which field, exactly?
Antenna design is very much a specialist subject - requiring specialist skills, experience, test equipment, etc.
You will be far better off using a module which either includes the antenna, or provides a connector for a ready-made antenna.
Thanks for your reply.
So I think nRF52832 doesn't have a built-in Bluetooth antenna. When I look for a ready-made antenna, what specifications I should care about? and the nfc antenna as well?
