I’m working with an ESP32 Super Mini in an entirely indoor setup where solid walls are the chief obstacle between the module and my router. Out-of-the-box performance is disappointing, so I haven’t moved beyond the stock PCB trace; no repositioning tricks or external antennas have been tried. I’d like you to guide me through (or design for me) an antenna modification that materially extends the unit’s range while keeping the overall footprint small. Practical advice on matching networks, ground-plane tweaks, or a compact external antenna design is welcome—as long as it improves signal strength through those walls. Deliverables • A schematic and physical layout (or clear step-by-step photographs) of the proposed antenna modification, tailored to the ESP32 Super Mini form factor. • Bill of materials with component values for any matching network or external parts. • Short test procedure showing before-and-after RSSI or throughput results so we can confirm measurable improvement indoors with walls in the path. You’re free to lean on RF simulation tools, a VNA, or empirical tuning—just be ready to explain the rationale so I can replicate the steps on my bench.

Hello, I have hands-on experience in RF and antenna design, and I can help you significantly improve the indoor range of your ESP32 Super Mini, especially in environments where walls are the main obstacle. Poor performance is often caused by antenna placement, insufficient ground reference, or an unmatched RF path, and these issues can be corrected without greatly increasing board size. I can design or guide you through a compact antenna modification tailored to the ESP32 Super Mini, including optimized antenna routing or an external antenna option, along with a proper matching network and ground-plane improvements to improve signal strength and wall penetration. Deliverables will include a schematic and physical layout (or step-by-step modification guide), a BOM with matching network component values, and a simple test procedure comparing before-and-after RSSI or throughput so improvements can be measured on your bench. I can also explain the tuning approach so future adjustments remain easy to replicate. I’d be happy to review your board photos or layout and propose the best modification to increase range while keeping the footprint small. Best regards, Srijan

Hi, I am Senior engineer space designs for transceivers. On the esp32 mini its usign a very tiny antenna, if it can be replaced by a larger 1/4 lambda for example this shold improve, if a directional antenna is possible even more I can design such an antenna, you might need to solder the contacts greeting rdk
