小型化UHF RFID抗金属标签天线的设计

一种小型化UHF RFID抗金属标签天线的设计

内容简介：针对射频识别(RFID)标签天线小型化、抗金属环境的实际需求,利用PIFA天线的设计原理和开槽线技术,设计了一种基于微带天线结构的抗金属标签天线,将原有标签尺寸缩小近2/3,该标签天线工作频段为860~960 MHz,尺寸约30 mm×30 mm×4 mm,置于180 mm×180 mm的金属板上,增益大小为3 dBi左右,频段内驻波小于1.5,满足了标签小型化、抗金属、低成本的要求.

Abstract：According to the actual demand of miniaturization anti?metal environment for the radio frequency identification (RFID)tag antenna,a kind of tag antenna based on micro?strip antenna structure was designed with PIFA antenna principle and slotted line technology. The size of the tag was decreased to one?third as the original one. The work frequency band of the tag antenna is 860~960 MHz,its size is 30 mm×30 mm×4 mm,and the gain is 3 dBi. It is mounted on the 180 mm×180 mm metal plate. VSWR is less than 1.5 in the frequency range. It meets the demands of miniaturization,anti?metal and low cost.
