Increasing of RFID System Read Range

Abstract

This paper describes some computations needed to increase RFID system read range twice without any changes in RFID reader. The increasing of read range is done only by proper selection of RFID marker parameters – coil diameter and number of turns. Another way – generating stronger magnetic field from reader – can not be used because requirements ofsome limitations given by valid standards must be taken into account.
