Re: ESP32 PCB Antenna Design

Hi Prasad, you can download the modules' reference designs from www.espressif.com/en/support/download/documents , ESP32-WROOM-32D and ESP32-WROVER-B have the latest antenna designs. You may also directly use modules, unless you have reasons for designing your own layout.
