ANTENNAS WITH UNIQUE ELECTRONIC SIGNATURE

摘要

Methods and apparatus are disclosed for manufacturing antennas with a unique signature and for identifying an antenna using its unique signature. An exemplary antenna comprises a radiating element and a ground element, between which a resistor-inductor-capacitor (RLC) circuit is connected. The RLC circuit is designed to generate a return-loss profile that serves as a unique antenna signature. The return-loss profile of the RLC circuit exhibits a resonance frequency outside the antenna's working bandwidth.
