3.6.6 Antenna circuit
The Transceiver circuit is divided into 3 Parts: the Antenna, Matching Circuit, and EMC
Filter. The matching part of the transceiver circuit is responsible for the matching
resistance of the whole Tx circuit. To tune your Antenna to the target resistance C1 and
C2 have to be adjusted. For more information’s about Antenna design and Tuning see
AN11019 (“CLRC Antenna Design Guide”) and AN78010 (“13.56 MHz RFID Proximity
Antennas”).
