Resistive and conductive fabrics sometimes referred to as electro-textiles have wide applications in RFI shielding, anti-static, RFID, wearable antennas, radar absorbing materials for military and automotive applications. Many commercially available conductive and resistive fabrics do not have material specifications at millimeter-wave frequencies such as 77 GHz of interest here. Therefore, the easiest...
Active RFID sensors are increasingly replacing their wired counterparts. However, their need for batteries, high unit costs and vulnerability to harsh environmental conditions (i.e., vibration, shock, temperature) make the passive RFIDs a favored option, even if they are associated with shorter distance detections. In addition to their limited read range, current passive sensor tags are relatively...
Harmonic radar systems provide an effective modality for tracking insect behavior. This letter presents a harmonic radar system proposed to track the migration of the Emerald Ash Borer (EAB). The system offers a unique combination of portability, low power and small tag design. It is comprised of a compact radar unit and a passive RF tag for mounting on the insect. The radar unit transmits a 5.96...
