Comparison of Different Electromagnetic Solvers for Modeling of Inkjet Printed RFID Humidity Sensor

چکیده
This paper focuses on the EM modeling of an inkjet printed humidity sensor for UHF RFID systems originally presented in [1]. EM modeling is used to predict the sensor readings as well as to design the tag for certain operating frequencies. Therefore accurate EM modeling is crucial. This paper presents a comparison between three different types of EM solvers in modeling of the humidity sensor; ADS Momentum, Ansoft HFSS and CEMS. As a result, the ADS Momentum managed to predict the impedance matching of the tag most accurately. This suggests that Momentum, whose solving method is based on the method of moments, is best suited for modeling such thin and complex RFID tags.
