Hybrid Frequency‐Polarisation Coding Method for Chipless Radio‐Frequency Identification Tags With Angular Orientation

IET Microwaves, Antennas &Propagation, Volume 19, Issue 1, January/December 2025.
In this paper, a hybrid coding method for chipless radio‐frequency identification (RFID) tag with angular orientation is proposed. Frequency‐shift coding is achieved by controlling the size of three complementary split single ring resonators (CSSRR). And on the basis, we add a dimension of polarisation coding, which is achieved through changes in the ...
