Designing an antenna for MAX66300

The purpose of this application note is to give more information on how to implement an antenna design needed for the MAX66300 NFC/RFID Reader and Authenticator IC.

MAX66300 Analog Front-End Description
The MAX66300 analog front-end (AFE) integrates a transmission and reception chain compliant with all the 13.56MHz air interface standards.
In effect, the MAX66300 internal Configuration Word register (Option bits) permits setting the following parameters:
Uplink communication (reader to tag):
  – Modulation index: 100% or 7% to 30%
  – Data rate and data encoding, frames
Downlink communication (tag to reader):
  – Subcarriers: 424kHz to 484kHz (ISO 15693). The user can adapt the reader chip internal filters to get the maximum
    performance.
  – Data rate, data encoding, frames.
The different configurations, offered by the reader chip, that the MAX66300 supports:
  – ISO 15693 standard
