Hi:
Since your notebook comes with the Realtek RTL8723DE Wi-Fi adapter, there is only one Wi-Fi antenna wire connected to it.
There is only one dual band AC Wi-Fi adapter where the Wi-Fi and Bluetooth both work with one antenna wire and that is this model:
Realtek RTL8821CE 802.11 ac 1x1 Wi-Fi + Bluetooth 4.2 Combo Adapter (MU-MIMO supported) HP part # L17365-005.
The card has a maximum throughput of 433 MBPS on the 5.0 GHz Wi-Fi band with an AC router and an excellent signal.
You can find this model on eBay, or Ali Express.
I see some Intel 3165 cards listed on the eBay listings, so don't buy those.

RTL8821CE - Buy RTL8821CE with free shipping on AliExpress
On the Ali Express listings, make sure the card has the HP Part # of 915620-001.
Below is the link to the service manual, where you can find the Wi-Fi card removal and replacement procedure.
