Abstract :
This paper presents develop of insensitive RFID tag independent about variation of chip impedance. Designed tag antenna is operate at 900MHz bands, and it´s performances is maintained when reactance of the chip is changed. If chip reactance changes from -J80 ~ -J270 ohm, this tag takes -10 dB bandwidth in 900 MHz bands. Moreover we confirmed that this tag antenna has ability to use commercial chip model.
