About this Gig

Are you developing a wearable device with a metal enclosure and facing antenna performance issues? Metal housing significantly affects RF radiation efficiency, impedance matching, and signal stability. I provide professional flex PCB antenna design and RF simulation tailored specifically for wearable electronics operating in challenging environments.

I specialize in flex PCB (FPC) antenna layout, impedance matching networks, and electromagnetic optimization for compact devices such as smartwatches, smart bands, AR/VR wearables, smart glasses, medical wearables, and IoT products. Whether your device uses Bluetooth, BLE, WiFi, or ESP32 modules, I design antennas that maintain stable connectivity even inside metal frames and shielded enclosures.

My service includes antenna structure design, S11 return loss optimization, impedance tuning to 50Ω, ground clearance analysis, and radiation efficiency improvement. I simulate and validate performance before fabrication to reduce costly prototype iterations. Special focus is given to detuning effects caused by batteries, displays, shielding cans, and metal casings.
