PN7160 antenna design and matching guide
●PN7160 is a highly integrated NFC transceiver IC for contactless communication at 13.56 MHz. This transceiver IC utilizes an outstanding modulation and demodulation concept completely integrated for different kinds of contactless communication methods and protocols at 13.56 MHz.
●It is able to operate both in reader/poller mode and in card/listener mode.
●PN7160 is intended to be connected to an external coil antenna through a specific matching/tuning network.
●The purpose of this document is first to provide some guidelines regarding the design of an NFC antenna intended to be connected to PN7160 (recommended antenna characteristics).
●It then depicts a measurement method to evaluate the performances of the antenna before it is connected to NXP NFC chips.
●The next chapter explains how to determine the tuning/matching network to be placed between a given antenna and PN7160 (based on the antenna electrical equivalent circuit).
●RF performance validation procedure is finally proposed.
