Compact and Lightweight Harmonic Tags for Insect Tracking with an X-Band Harmonic Radar

This paper presents novel printed harmonic tags designed for use with an X-band harmonic radar. Compared to conventional wire-based tags, the presented tags are more compact and do not require additional support structures to mount on an insect. At the same time, they are significantly lighter than previously reported printed designs, weighing less than 5 mg. Their performance was validated through measurements, confirming their potential for insect tracking applications.
