HP does not supply its parts list

From page 51 of its manual, you can use one of the following wifi adapters

• Intel Dual band wireless-AC 3168 802.11AC 1×1 WiFi + Bluetooth 4.2 Combo Adapter (non-vPro) part # 863934-855
• Realtek RTL8822BE 802.11 ac 2×2 WiFi + Bluetooth 4.2 Combo Adapter (MU-MIMO supported) part # 924813-855
• Realtek RTL8821CE 802.11 ac 1×1 WiFi + Bluetooth 4.2 Combo Adapter (MU-MIMO supported) part # L17365-005
• Realtek RTL8723DE 802.11 bgn 1×1 WiFi + Bluetooth 4.2 Combo Adapter part # L21480-005

I see some says that my labtop contains only one antenna wire connected to the Realtek Wi-Fi card. so will these card all compatible with it?

The above list is from the manual of the series. Since your machine only has 1 antenna, you can use any 1x1 adapters.

The only Wi-Fi adapter where both the Wi-Fi and Bluetooth will work with one antenna wire is this one:

Realtek RTL8821CE 802.11 ac 1×1 Wi-Fi + Bluetooth 4.2 Combo Adapter (MU-MIMO supported)  HP part # L17365-005

While the Intel Dual band wireless-AC 3168 is a 1 x 1 Wi-Fi adapter, that card was engineered to work with two antenna wires. 

The main antenna wire for Wi-Fi and the auxiliary antenna wire for Bluetooth.
