Maybe someone can tell me.,
where should I solder the external antenna in the ESP32-S3-Nano board?
Is that board supposed to have an external antenna connector ?
There is no connector for the antenna, is there a way to connect it somewhere ?
solder it with a cable..
I moved your topic to a more appropriate forum category @rz1zr.
The Nano Family > Nano ESP32 category you chose is only used for discussions directly related to the official Arduino Nano ESP32 board. Despite the similar name, the ESP32-S3-Nano is different from the official Arduino Nano ESP32 (the ESP32-S3-Nano is a Chinese derivative of the Arduino Nano ESP32).
In the future, when creating a topic please take the time to pick the forum category that best suits the subject of your question. There is an "About the _____ category" topic at the top of each category that explains its purpose.
This is the second time I've had to explain this to you. If you won't respond to polite requests, I'll be forced to resort to an account suspension. I don't want to do that, and I'm sure you don't want that either. So please pay more attention!
Thanks in advance for your cooperation.

The red part is the aerial.
It is soldered to the board on two sides, but one side is likely a dummy pad (not connected to anything). Swipe off the red part with a soldering iron.
Solder the core of the coax of the external aerial to the pad that is not the dummy pad.
Scrape the paint off a small area of the ground plane next to the red part, and solder the shield of the coax to that.

Wawa, I really appreciate the hint, I'll try to do it, thank you!
The trick with these high frequencies (2.4GHz) is to keep connections short.

Yes, I understand what you're talking about..
