Investigation of Characteristics of RFID-antennas with Different Configurations of Microstrip Meander-line

The theme: "Investigation of Characteristics of RFID-antennas with Different Configurations of Microstrip Meander-line" The graduation thesis - master's thesis consists of 60 pages with 40 figures and 1 table. While writing the thesis 30 reference sources were used. The paper includes the following sections: introduction, four chapters, conclusion and references. The applicability of the chosen theme is shown in the introduction. Also, the introduction provides an assessment of the current state of RFID technology, defines the purpose of the paper and tasks to achieve the goal. The first chapter provides an overview of RFID tags, its components, and the main parameters of the antennas used for radio frequency identification. The technical implementation of RFID tags, the advantages of using antennas with a microstrip meander line, as well as the topology of such RFID antennas, are described in the second chapter. In the third chapter, the analysis of radiation patterns and amplification of RFID antennas with various configurations of a microstrip meander line at operating frequencies 866 and 915 MHz was carried out using the MMANA-GAL program. In the fourth chapter, the MathCAD program calculates and analyzes the range of RFID antennas with different configurations of a microstrip meander line at 866 and 915 MHz operating frequencies. The final part contains conclusions are drawn about the effect of the meander-structure period, the configuration of the microstrip meander line and the operating frequency on the radiation pattern, the gain and range of the antenna, and the possibility of using RFID antennas with various configurations of the microstrip meander for radio frequency identification at 866 MHz and 915 MHz.
