ANTENNAS WITH UNIQUE ELECTRONIC SIGNATURE

摘要

Methods and apparatus are disclosed for manufacturing antennas (100) with a unique signature and for identifying an antenna (100) using its unique signature. An exemplary antenna comprises a radiating element (104) and a ground element (102), between which a resistor-inductor-capacitor (RLC) circuit (106) is connected. The RLC circuit (106) is designed to generate a return-loss profile that serves as a unique antenna signature. The return-loss profile of the RLC circuit (106) exhibits a resonance frequency outside the antenna's working bandwidth.
