Reader systems for passive RFID tags suffer
from a strong self generated interferer at the receiver, caused
by transmitter to receiver leakage. This problem is often
addressed by leaking carrier cancelers which compensate
the leaking carrier at a single frequency. In this paper we
present measurements of the leakage channel in an RFID
system. Based on the obtained results, we evaluate the leakage
reduction that can be achieved by a novel analog broadband
leakage canceller in the RF domain. Our proposed method
allows for suppression of transmitter noise components.
Moreover, it facilitates new broadband technologies, such as
precision localisation or chipless RFID.
