Cheaper WIFI Card

Hey Guys,

i am searching for the cheapest option to use Airdrop on my Ryzen Hackintosh. I guess this is a frequently asked question, but im just not an expert in this whole WIFI/Airport thing and just don't understand most of the tips given. I don't really care about the the WIFI itself, because i manly use LAN. The Card should be compatible with Big Sur, and hopfully it works with the upcoming versions.

Thanks for your time.
