N2 - A novel passive RFID tag for a long reading range composed of a divided microstrip antenna and a rectifying circuit boosting the DC voltage is proposed. Experimental study of fabricated passive tag using varactor diodes, in which 30 m range response can be achieved at 860-950 MHz band, is described. Passive tags for temperature-monitoring system at 2.45 GHz band is also fabricated to demonstrate validity of proposed tags for a range longer than 9 m. The tags have sizes of 90×60×4 mm and 60×25×4 mm for 900 MHz and 2.45 GHz bands, respectively.
