How many Wifi antennas does my laptop currently have?

[JoeyGlands]

Hello, my current Wifi adapter does not support 5GHz signal, I'm planning on replacing it with an adapter that does.

I'm trying to determine how many Wifi antennas I currently on my laptop, I'm suspecting it has one antenna because my network adapter is "RTL8723DE"

How many WiFi antennas does my laptop have? I appreciate your expertise and help.

Hi, @JoeyGlands 

There is only one model AC wifi card where the wifi and bluetooth both work with one antenna cable, and that is this one...

Realtek RTL8821CE 802.11 ac 1x1 WiFi + Bluetooth 4.2 Combo Adapter (MU-MIMO supported) HP part # L17365-005.

The only place I have been able to find this model is on eBay.

The card has the same throughput as the RTL8723DE on the 2.4 GHz wifi band, but on the 5.0 GHz wifi band with an AC router, it has a maximum throughput of 433 MBPS.

On a dual band wireless N router, it would have a maximum throughput of 150 MBPS on the 5.0 GHz wifi band.
