BLUETOOTH ANTENNA

[BILLGR72]

I have a bluetooth module HW-770C V3.1{receiver} how can i add a antenna for better receive.

I think that it’s possible to add an external antenna.
Cut the PCB antenna traces to eliminate it and use either a SMA or U.FL connector.
Then screw on a 2.4g antenna.
I’m not sure whether impedance matching will be an issue though.
The Bluetooth IC data sheet may give that information.

Typically the BT chip datasheets have recommended antenna interface design layouts.

If all they give you is S parameters ...
