Questions about my Asus motherboard's Wifi+Bluetooth module's Antenna

[mkanet]

I have an older Z97 Deluxe Motherboard with builtin 802.11ac + Bluetooth 4.0. I would like to replace the antenna with the best aftermarket antenna.

Is the antenna also responsible for Bluetooth reception; or, is it only for Wi-Fi.

I found a couple of antennas (below). However, I'm not sure if there is one that I can buy with better reception; especially, if it will help Bluetooth connectivity.

Could someone please recommend the best replacement antenna I can buy that's compatible?

Season's Greetings!

99% of the time, the BT antenna is integrated into the PCB of the combo WiFi/BT card, with no connection to external antennas.
