摘　　要：本文研究了V形无芯片标签的散射特性,并通过检测标签散射场在水平和垂直两个方向的分量,识别出每个标签.考虑到实际操作中标签不可能与入射信号始终保持垂直关系,研究了标签倾斜时的识别误差.此外,还研究了均匀平面波垂直和斜入射到标签时,在倾斜方向接收到的散射场的分布情况,及标签的识别结果.结果表明:准确识别标签的收发装置之间的最大夹角为10°.This issue studies the scattering characteristics of the V-shaped chipless tag.It is identified by measuring the scattered field in the horizontal and vertical directions.Considering the actual operation,it is difficult to always keep vertical between the tag and the incident signal,so we study the case that the tag is tilted.In addition,the issue also presents scattering fields and the identification results in the oblique direction when the plane wave incidences to the tag in the vertical and oblique direction.The simulation results show that the biggest angle is 10°between sending and receiving devices for identifying tags accurately.
