Effect of shape and surroundings on harmonic transponder performance

Harmonic transponders utilise two distinct, harmonically spaced frequencies to communicate with the reader device. For efficient performance, the transponder antenna needs to be properly matched at these frequencies. This work investigates how the transponder performance is affected when the shape of the transponder changes through bending or when the transponder is in the proximity of an object with varying material parameters. The obtained results show that the performance of the transponder is more affected by the properties of the object it is attached to. With different bending states, the harmonic response of the transponder does not change significantly, meaning that the design could be suitable for conformal applications.
