This document is aimed at providing 13.56 MHz RFID systems designers with a practical cookbook on how to optimize RFID systems and antennas. A thorough analysis of the most important RFID system
Ideally I'd like something that had a 3 to 4 foot range, but given that doesn't seem to be possibly with anything non powered currently, I need to find better ways of fitting a regular RFID read close enough to where I want to make the short range work for me. For example.How to design a 13.56 MHz customized antenna for ST25 NFC / RFID Tags. Introduction. The ST25 NFC (near field communication) and RFID (radio frequency identification) tags extract their power from the reader field. The tag and reader antennas are inductances mutually coupled by the magnetic field, similarly to a voltage transformer (see Figure 1).
For engineers who work in RFID antenna test, this note discusses 13.56 MHz RFID antenna testing and designing with network and impedance analyzers. Learn more! rf spectrum rfid 13.56 Reader IC manufacturers, e.g. Philips/NXP have data sheets and application notes that discusses antenna matching. Knowing the L and R of your coupler coil, you are able to calculate a matching circuit and necessary input power to achieve a certain field strength at the tag location.
Abstract: Since RFID technology is developed, 13.56 MHz RFID system with its excellent performance is widely applied. 13.56MHz RFID system is a passive system. So the performance of the antenna directly affects the performance of the RFID system.
