rfid tag capacitor Capacitor Tuning the RFID tag to resonate at the carrier frequency produces the maximum communication range. This tuning is accomplished by matching the antenna inductance with a tuning capacitor to produce resonance at 13.56 MHz. The equation for resonance is: For these RFID ICs, the resonant frequency f0 is 13.56 MHz, L is the antenna Try the phone App first to get the hang of it. Easier for testing and understanding the whole .

This tuning is accomplished by matching the antenna inductance with a tuning capacitor to produce resonance at 13.56 MHz. The equation for resonance is: For these RFID ICs, the resonant frequency f0 is 13.56 MHz, L is the antenna The frequency at which the circuit has the optimal (maximal) response, its resonance frequency, is determined by the value of the capacitor and inductor (see the resonance frequency in the linked Wikipedia article).A passive RFID tag contains an RFID integrated circuit (IC), resonant capacitor (C), and antenna (L), as shown in Figure 1. The antenna and capacitor form a parallel LC resonant circuit. The LC circuit must be tuned to the reader’s carrier frequency for maximum performance (read range).

For 13.56 MHz passive tag applications, a few microhenries of inductance and a few hundred pF of resonant capacitor are typically used. The voltage transfer between the reader and tag coils is accom-plished through inductive coupling between the two coils.In this paper, a printed RFID tag and rectifier circuit manufactured a using low-cost screen printing process is presented. The capacitors of rectifier circuit are made of flexible high dielectric constant (Hi-DK) It seems that each I/O pin has a parasite capacitor and a pair of clamping diodes inside the chip. When the AC current that is induced by the magnetic field of the RFID reader hits those pins,.

In order to ease RFID tag design, decrease cost and improve Transponders and Tags performances, IPDiA launched a full range of RFID capacitors, offering a broad range from 10pF to 330pF with High Q and High SRF to fulfill to all requirements. These Silicon capacitors offer no capacitance drift upon applied voltage In order to ease RFID tag design, Murata launched a full range of low profile RFID capacitors, offering a broad range from 10pF to 330pF. Manufacturing process was adjusted to address the key electrical parameters. When the reader initiates a data exchange it first drives the antenna for, typically, 15 to 50 msec. That excites the resonant circuit on the tag and charges the capacitor. Data is exchanged using backscatter modulation. As the tag switches a load on and off, the reader's antenna experiences a change in voltage.
