Návrh antény pro systémy RFID (Radio Frequency IDentification - bezkontaktní identifikační systém)

Abstract

This thesis deal with antenna design and its adapter circuit for radio frequency identification (RFID) in the frequency band from 13,56 MHz. The first part of the thesis, focuses on general knowledge of systems RFID and frequency band usage itself. Further on a proposal modeling of suitable antennas for choice of frequenci band in commercial simulator CST Microwave Studio is dealt with. On the basic of the results gained this way an optimal antenna is selected. It is then implemented including an adapter circuit and its parameter is subsequently examined in practice. The aim is to find an antenna with the widest reach for the frequency mentioned above and a specific reader on wich the antenna will be tested.
