Abstract :
A novel design of a transmission line suitable for leakage field coupling towards RFID inlays at UHF frequencies is presented. The theory of the phase compensating element used in a cascaded configuration for the segmented transmission line is described. The principle is verified by an exemplary design with predicted results from FEM simulations and testing performed with fabricated prototypes.
