Hi, are you meaning that you want to place an 2.4GHz chip antenna?

Or do you want to draw a PCB antenna?

I wish to hear more about "my own antenna", please.

Hi Mango922, Thanks for replying.Yes, im trying to edit this schematic diagram by adding a 2.4 - 2.45GHz, 50 ohm and omni directional bluetooth chip PCB antenna for detecting proximites abt 2m between users. i am using a software called Altium designer before sending it for fabrication. but i have no idea which part of the diagram should i remove? should i remove only the antenna part or including L1 and C4?

Hi. A "Bluetooth chip PCB antenna". Are you meaning something like this chip antenna?

I didn't hear about an antenna that can be both chip and PCB at the same time.

Don't remove C4 and L1. Those parts are for antenna tuning.

However, the value of the parts will vary.

For further questions, I think the Nordic developers can help you.

Also, do you have a link or a datasheet of your antenna?

-Best Regards
