hello, I'm currently designing a PCB using a ESP32 DevKitC board. and I was wondering if my current design will interfere with the WIFI antenna
specifically, that 7.4V signal is directly under where the WIFI antenna would be. because of where the rest of the signals are, it would be difficult to move it, but I could try if I had too.
Thanks for the help in advance.
Is there a reason why you posted this topic in the Opta category of the forum ?
um, no. if I did I didnt mean to. sorry.
I managed to reroute that trace, but I cant for this one, will it interfere?
Your topic has been moved to a more appropriate forum category
Anything under the antenna may interfere. So don't route anything under the antenna. Use working examples as models.
Get rid of all the copper, including what I assume is a ground plane, from under the antenna.
Not part of your question but you shouldn't slice a ground plane in half like that.
A transmitting antenna is not just a piece of wire but it is a carefully crafted series resonant circuit tuned to the output frequency of the transmitter so that it can accept and radiate all the signal energy given to it. If you put conductors near the antenna, you add capacitance to its circuit and that changes its tuning thus decreasing its efficiency.
Something I could do then would be to move the ESP32 up making it so the anena is handing off the board. then figure out routing from there.
