That's about it. Antennas aren't anything but wire or a small sheet of metal, all you need is something to increase the amount of metal exposed to the signal.

This is a quick & dirty diy "solder on some more metal & an antenna" tutorial:

Solder mask might have been a better cover than the one shown, but the hot glue would do in a pinch.
Also, as far as resistor goes, there is no spec for the resistor. It's a jumper, that's all.
- jve 3y agoExcellent article! This is what I was hoping to find. Luckily I have some solder mask and UV light laying around :) Thank you.
- frontierkodiak 3y agoYMMV, but I have tried this several times and have found it very difficult without microsoldering equipment. Some ESP variants have a built-in U.FL connector which makes things easier (e.g. AITHINKER ESP32-Cam and its many clones), but you still have to remove the 0Ω resistor, which I find very difficult with even the smallest tips on my Hakko iron. Could be a skill issue on my end; should be much easier if you have a simple reflow/rework station.
