The demo supports ISO/IEC 15693, ISO/IEC 14443A, and ISO/IEC 14443B communication protocols. This application report describes a simple demo of antenna multiplexing that can help when using the TRF7970A in applications with multiple antennas.
NFC tags are powered by the NFC reader using magnetic coupling (so called near field). You .
The demo supports ISO/IEC 15693, ISO/IEC 14443A, and ISO/IEC 14443B communication protocols. This application report describes a simple demo of antenna multiplexing that can help when using the TRF7970A in applications with multiple antennas.NFC tags are powered by the NFC reader using magnetic coupling (so called near field). You need to research the use of much smaller loop antennas which will control the distance over which you can power the transponder NFC tags.
I have an application whereby I need to use one reader IC with 10 antennas. It does not need to read very quickly, once per second or so. What is the best way to do this? Each antenna will be about 1.5" (38mm) spacing in a line. So the length of the farthest antenna is about 15" (380mm) from the IC. Application is like a vending machine. Should I:A contactless reader/NFC design might require multiple tap points for credentials and/or phones. In order to keep the system cost as low as possible, this functionality can be achieved using multiple antennas with a single contactless reader IC.In Figures 1 and 2, the NFC reader excites current at 13.56 MHz through the reader NFC antenna (which is really an inductor). This induces a magnetic field, which furthur (via mutual coupling) induces an electric current in the smartphone's NFC antenna when they are closely placed.How to design an antenna for dynamic NFC tags. Introduction. The dynamic NFC (near field communication) tag devices manufactured by ST feature an EEPROM that can be accessed either through a low-power I2C interface or an RF contactless interface operating at 13.56 MHz.

Explore the hub and download the Antenna Design Tool for faster antenna tuning and matching. It has a simple GUI to make it very easy to start designing and simulating antennas and it works with all standard NXP NFC Reader ICs on the market.1. Introduction. Scope. The document will introduce the MiniVNA Pro instrument for measuring HF loop antenna parameters and antenna matching for NXP RFID transceiver. Compared to classical Vector Network Analyzer this instrument is cheap and portable. As of very recently, there is a new NXP antenna design tool which includes antenna design guidance for passive tags/connected tags, and reader antennas (vs. just reader antennas), with pre-loaded parameters for most NXP IC offerings. Check out the NFC Antenna Tool to find out more.
To reduce the cost of our RFID reader, we would like to use an HTRC110 to control 2 antennas using a multiplixing system. I found application note AN11314 which describes how to use a single reader with multiple antennas.The demo supports ISO/IEC 15693, ISO/IEC 14443A, and ISO/IEC 14443B communication protocols.
