Welcome to Apple Support Communities
The only Mac with a 802.11ac AirPort card is the Mid 2013 MacBook Air, and it has got problems related to the Wi-Fi. The most recent Mac mini isn't compatible with 802.11ac networks at the moment, but it's quite possible that Apple will include it in a future Mac mini launch, but it's difficult that it will be launched for old Macs.
Instead of getting a new Mac mini in the future, one thing you can do is to get a 802.11ac wireless adapter that you can connect by USB to your Mac mini, so you can use 802.11ac networks. There are a lot in the Internet, and you just have to be sure that it works with OS X
