Abstract
An electrically large zero-phase-shift line (ZPSL) segmented loop antenna backed by an inductive perforated ground plane is proposed for ultra-high frequency near-field RFID systems. The ZPSL segmented loop configuration enables a uniform distribution of magnetic field over an electrically large interrogation zone, while the backed inductive perforated ground plane is introduced to realize a stronger magnetic field for a longer reading range, even with a thinner overall profile as compared with a metal ground plane backed counterpart.
