| Abstract(in English) | Novel 5GHz band semi-passive sensor RF-tag for low power consumption and long reading range is proposed. Tag is composed of a sensor, a wearable cavity-backed slot antenna, a resonant short stub circuit for boosting the rectified DC voltage and a pulse key detector for the wake up operation. Subcarrier multilevel phase shift keying (MPSK) is employed for continuous data communications and distance measurement. Experimental study of fabricated semi-passive RF-tags, i.e., tags for distance measurement and sensing data monitor, is presented in which 20m range response can be achieved by the 20dBm RF output power of reader at 5GHz band. Current requirements of battery in these tags are 800μA (20sps) and 1200μA (10kbps), respectively, which are much smaller than conventional active RF-tags. |
