13,56 MHz RFID antenna for cell phone integrated reader

This paper defines the model and attributes of the cell phone integrated antenna design for the mobile RFID reader using 13 and 56 MHz frequency. This HF frequency band is the most common and fastest growing band used in RFID applications.Radio frequency identification (RFID) is becoming more and more common and its application range is widening continuously. The benefits of RFID are obvious compared to former identification systems, like barcodes. For example, RFID does not need a direct line of sight between the reader and the tag. The development of RFID tags has put pressure on the development of the readers, too, and especially the need of mobile readers has increased through the significant widening of the application range. Because of the presumption that cell phones are nowadays carried by almost all people, they would make a suitable and useful platform for mobile RFID readers as well, as presented in reference. The possibilities and techniques of integrating the RF-part and the user interface (UI) of the RFID reader in the cell phone are presented in future references.
