Návrh antény pro aplikace RFID

Abstract

The aim of this diploma thesis is the design and implementation of an antenna for the use of RFID technology and the assembly of a reading system for the Arduino UNO R3 platform. The antenna will identify tags in the near field, so it is more of a design of a loop antenna to create an inductive bond between the designed antenna and the antenna of the tag or card. The system ensures the identification of the user when entering the object. The user will not be allowed to enter the object without verifying his card. The required card verification range is 20 cm. An antenna tuned to 13.56 MHz was designed for RFID technology. The solution of adapting the antenna to the reader was part of the antenna design. The functionality of the antenna at the required frequency was verified by a practical implementation of the entire system and a practical test of identifying the correct card and the card with the wrong code. The antenna design was verified by measurements on a VNA mini PRO vector analyzer. Verification of the whole system was performed in laboratory conditions.
