摘要

提出了一种用于超高频近场RFID系统的电感式穿孔接地面的电大零相移线(ZPSL)分段环路天线。ZPSL分段环路配置使磁场均匀分布在一个电大的询问区，而背面的感应穿孔接地面被引入实现更强的磁场，更长的读取范围，即使与金属接地面相比，更薄的整体轮廓。

An Inductive Perforated Ground Backed Thin Electrically Large Zero-Phase-Shift Line Loop Antenna for UHF Near-Field RFID Reader

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.
