Research of Antenna on Circular Microstrip Meander-Line for RFID

The theme: "Research of Antenna on Circular Microstrip Meander-Line for RFID" The graduation thesis consists of 46 pages with 18 figures. While writing the thesis 16 reference sources were used. The paper includes the following sections: introduction, four chapters, conclusion, list of symbols 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 technology and its components, and the frequency bands used for radio frequency identification. The design and methods of calculation of microstrip antennas, as well as the advantages of using the meander-line antennas of this type, are described in the second chapter. The third chapter is a comparison of programs for modeling antennas. The fourth chapter via MMANA-GAL program analysis patterns carried out for the two types of microstrip antennas with different meander-period structure, and with different widths of the microstrip conductor at the frequencies 866 and 915 MHz. The final part contains conclusions on the impact of the period of the meander structure, the operating frequency and the width of the microstrip conductor on the antenna pattern and the possibility of using the transmitter on the circular microstrip meander-line RFID frequencies in the 866 MHz and 915 MHz.
