摘　　要：设计了一款能应用于金属货物识别的新型标签天线——准八木标签天线。基于折合振子和错位阵列技术,并使用高介电常数的介质基材,使天线的厚度限制在0.024λ,从而满足标签天线尺寸的要求。经实测验证,新型天线贴附在金属物体表面时,能达到5dBi的增益。This paper presents a novel quasi Yagi tag antenna for RFID of metallic object. 5 dBi antenna gain is achieved when the antenna is mounted on a metal ground plane. The boom-length of antenna is limited in the range of based on several technologies, such as folded dipole, staggered array and the material with high permittivity to fit the requirement of tag with low profile.
