[SOLVED] Why 1x1 laptop wifi cards have 2 antenna terminals?

[IlyaK]

Here is 1x1 card: https://images-na.ssl-images-amazon.com/images/I/81SsZv2ymrL._AC_SL1500_.jpg
One antenna, one terminal.

Here is 3x3: https://www.amazon.co.uk/Intel-Centrino-Ultimate-n-6300agn-633ANHMW/dp/B01795Y5NQ
It has 3 terminals.

Here is another 1x1: https://www.amazon.co.uk/Wireless-Network-3160HMW-433Mbps-Bluetooth-default/dp/B07VLMYV9N
As you can see, it has 2 terminals: 1 and 2.

What for?

Dual band. 1 antenna for 2.4 and one for 5Ghz. One of those probably also services bluetooth.

kanewolf, thank you!

I also found the following phrase:

1 = Main, left connector: Wi-Fi Tx/Rx
2 = Aux, right connector: Bluetooth Tx/R
In the Intel user manual.

It seems that it is used for BT, indeed.

Yeah this Intel board post confirms that -- https://community.intel.com/t5/Wire...-Intel-Dual-Band-Wireless-AC-3160/td-p/571241
