Abstract:
Radio frequency identi cation (RFID) is a rapidly growing technology area and it has numerous advantages such as none-LOS and contact-less operation, multiple tag identi cation, long read range and tag re-programmability. During last decade, smart phones began to spread tremendously and this fact makes RFID very popular for consumer applications. With new evolutions in chip technology, RFID has the potential to lead many industries. The aim of this thesis is to provide a design process for a 13.56 MHz RFID reader and antenna that used in a special TV application. The nal design is placed in a TV unit and it provides that only speci c users that equipped with particular passive cards can access particular menus and applications on TV. Therefore, users can control their personal menus and information in electronic device in a secure way. In this thesis, the design methodology of the reader and the antenna is presented and at the end of the work, the nal reader design achieves communication up to about 5 cm with passive cards which is desired operation distance for similar near eld communication applications. Also, return loss is obtained as 27 dB at operation frequency of 13.56 MHz.
