Long Range Passive Rfid Tag For Sensor Networks

Furthermore the long range rfid tags have a reading range that is usually up to 328 100 m and are designed with technology of low power consumption in order to ensure longer battery life.

Long range passive rfid tag for sensor networks. The study also demonstrates mathematically and experimentally that our proposed longest range uhf rfid cavity type tag antenna has a longer read range than existing passive tag antennas. Long range passive rfid tag for sensor networks published in. Long range passive rfid tag for sensor. 2005 ieee 62nd vehicular technology conference 2005.

Therefore it is strongly desired to develop an rfid tag applicable to a long reading range to realize novel communication network systems. High frequency hf passive rfid tags. This paper presents a passive cavity type ultra high frequency uhf radio frequency identification rfid tag antenna having the longest read range and compares it with existing long range uhf rfid tag antenna. In this paper we focus on uhf rfid long range passive tag antenna published from 2013 to now.

Long answer passive rfid. Long range passive rfid tag for sensor networks published in. The longest ranges of rfid tags using conventional dipole antenna have been 3 3 m at 2 45 ghz 1 and 9 25 m at 915 mhz 2. Unlike active rfid tags passive rfid tags only have two main components the tag s antenna and the microchip or integrated circuit ic.

It supports fast tag read write operation with high identification rate. The tags respond to different needs and are design to be suitable for multiple environments and purposes.

Generally speaking three main parts make up in a passive rfid system an rfid reader or interrogator an rfid antenna and rfid tags. 2005 ieee 62nd vehicular technology conference 2005. However even the read ranges of passive tags published before 2013 are shorter than the proposed one.
