Abstract: Backscatter communication (BackCom) has emerged as a promising solution for ultra-low-power wireless information transmissions. Traditionally, it is commonly assumed that BackCom links can only be established at the frequencies at which the backscatter tag antennas resonate. In our study, it has been shown that it is feasible for BackCom systems to operate beyond the antenna resonant frequencies. A novel scattering cross-section (SCS)-assisted optimization approach is proposed, where the operating bands of the system are defined based on the experimentally measured SCS of the entire tag rather than tag antenna resonant frequencies. Simulation results demonstrate that the BackCom system can operate effectively beyond narrow resonant frequencies, enabling more flexible frequency band selections. These findings highlight the significance of tag scattering characteristics in optimizing BackCom designs.
