UHF RFID CARPET ANTENNA

Start by cleaning the area with alcohol and, on metal, add the 0.5mm spacer to avoid RF loss. Use the built-in adhesive for temporary setups or conductive epoxy for permanent fixes on materials like ABS or PVC. When bending, keep at least a 3mm radius—tighter bends can cut gain. For pipes or cylinders, wrap the antenna lengthwise instead of around to keep the radiation pattern stable.

Pro Tip: Use a vector network analyzer to verify VSWR remains ≤1.8:1 post-installation.

The CK-FL1 can handle tough conditions thanks to its IP68 polyimide design, but very high humidity, chemical exposure, and extreme temperature swings need extra steps. In humid spaces over 90% RH, add a thin silicone coating to keep moisture out. For oil or gas sites, an FKM overlay protects against hydrocarbons and H₂S. With big temperature swings, give the antenna time to stabilize and use thermal gap pads on hot surfaces to prevent delamination. In one automotive plant, these measures helped maintain 99.3% read accuracy on engine blocks.

Mount the antenna on a conveyor running 2.5 m/s and test with dense tags at 30 dBm, aiming for at least 97% reads over eight hours. For rotating parts, attach to a drum and watch impedance drift and adhesive strength. If signals drop, look for micro-cracks; if read rates fluctuate, recalibrate with the tuning tool; if edges start peeling, let epoxy cure longer in cold conditions.
