measure the dielectric constant of the ESP32-Wrover module
I don't think it's easy to do that practically. One thing you can check for is the board stackup from the fabrication files or in the design itself.
By your intent to study characteristics, do you mean the antenna's frequency response? Have a look at this - it's pretty much standard evaluated design for the given stackup https://docs.espressif.com/projects/esp-hardware-design-guidelines/en/latest/esp32/pcb-layout-design.html (link updated)
