Advanced Low Power Long Distance RF-Tag Systems by Using Modulated Subcarrier Wave
Hitoshi Kitayoshi, Kunio Sawaya (Tohoku Univ.) SIS2007-47
Abstract (in Japanese) (See Japanese page) 
(in English) Novel semi-passive sensor RF-tags for a low power consumption and a long reading range are proposed. Tags are 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, is proposed. Experimental study of fabricated semi-passive RF-tags, i.e., tags for distance measurement, tri-axial acceleration sensor and electrocardiographic monitor, is presented, in which 35 m range response can be achieved in the 3mW/MHz ARIB STD-T81 reader at 2.45 GHz band. Current requirements of battery in these tags are 10uA (20sps), 633uA (350sps) and 583uA (350sps), respectively, which are much smaller than conventional active RF-tags.
