Prediction Method of RFID Antennas Detection Performance Based on Monte Carlo Analysis

Abstract

This paper presents a method to predict the detection performance of the RFID antenna based on Monte Carlo analysis. The specific designed reader antenna and the typical tags are modeled for electromagnetic simulations. The random numbers are generated by the Monte Carlo method to define the positions and orientations of the arrayed tags. Then, the transmission coefficients related to the different positions and orientations are developed to calculate the misreading probability of the reader antenna under different transmitting power levels. Finally, a passageway-type detection system has been built up to compare with the simulation results. The results show that the method proposed in this paper can better indicate the detection performance of an RFID antenna and provide a new prediction way for the design and application of RFID antennas.
