ISO 15693 ICODE2 RFID coil benefits and effects?

N&R technology supply varies of RFID coil antennas. Our RFID coil antennas are designed for RFID readers and RFID tags. There are many RFID coil antennas for your options. Different size, shape, chips. We also welcome OEM of RFID coil antennas.

 is a main limiting factor of the read range in RFID
applications.
When the time-varying magnetic field is passing
through a coil (antenna), it induces a voltage across the
coil terminal. This voltage is utilized to activate the
passive tag device. The antenna coil must be designed
to maximize this induced voltage.
This application note is written as a reference guide for
antenna coil designers and application engineers in the
RFID industry. It reviews basic electromagnetics
theories to understand the antenna coils, a procedure
for coil design, calculation and measurement of
inductance, an antenna-tuning method, and the
relationship between read range vs. size of antenna
RFID coil.
