Abstract

Passive harmonic transponders are used in applications where weight and size restrictions are prohibitive to the use of active radio transmitters, e.g., for insect tracking. A typical harmonic transponder tag consists of a wire dipole antenna and a Schottky diode with a parallel inductance. Despite the simplicity in tag circuit, designing lightweight, compact, and efficient harmonic tags are challenging. In this letter, we describe a design that combines the reliability of a printed circuit with the simplicity and small mass of a wire dipole antenna. We study the interplay of individual system parameters and show that optimizing the tag antenna together with the tuning inductance provides further opportunities for tag miniaturization.
