© 2021, The Author(s), under exclusive license to Springer Nature Switzerland AG.This paper aims to establish an analysis of the impact in the resonance frequency of a Radio Frequency Identification (RFID) inlay operating in Ultra High Frequency (UHF) by changing its internal dimensions. Obtaining the resonance frequency in terms of the S11 parameter is crucial in order to design RFID labels that meet specific requirements. The use of a Computer Aided Design (CAD) tool was considered to design the RFID inlay, while the simulations were performed using the MWS-CST Studio Student Edition software. Satisfactory results were met in order of verifying central frequency shifting as long as the internal dimensions of the inlay have been adjusted in two rounds of simulations. Additionally, it was possible to demonstrate a gain greater than 2 dB and 30 MHz bandwidth, showing that the tested conditions can be seen as a good starting point for future works to advance the studies in the context herein presented. The RFID tags designed in this paper benchmarks an antenna widespread in the RFID market. Meanwhile, the theoretical basis obtained by observing the antenna theory and analyzing the results has been used to contribute to all the process of building an RFID tag and stimulate the expansion of RFID technology worldwide.
