Designing Antenna-Friendly Enclosures for ESP32-S3: RF Clearance, Wall Thickness, and Material Loss
Placing an ESP32-S3 PCB inside a 3D-printed enclosure can degrade Wi-Fi and BLE signal strength by 3 dB to over 15 dB if you ignore ground plane clearance, dielectric loading, and filament selection. Here is the mechanical guide to preserving RF performance.
