| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | Novel 5 GHz 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 20 m range response can be achieved by the 20 dBm RF output power of reader at 5 GHz band. Current requirements of battery in these tags are 800μA (20sps) and 1200μA (10kbps), respectively, which are much smaller than conventional active RF-tags. | |
