一种激光全息RFID标签
摘要：
本实用新型公开了一种激光全息RFID标签，包括RFID标签（500）和贴装在该RFID标签（500）上的激光全息膜（10），其特征在于，所述激光全息膜（10）的金属反射层（103）为对称的两部分，该两部分之间留有隙缝或通过非磁性绝缘材料条相互隔开，使得两部分相互绝缘，其中，该隙缝或非磁性绝缘材料条位于所述RFID标签（500）的中心轴线上。本实用新型通过将全息膜金属层分成对称的两部分来消除全息膜金属层对电磁波的屏蔽，通过改进天线设计来消除全息膜对天线阻抗的影响，对全息膜的尺寸没有限制，并能够增强天线的辐射，提高RFID标签的读取距离。
摘要（英）：

The utility model discloses a radio frequency identification device (RFID) label with a laser hologram, which comprises an RFID label (500) and a laser hologram membrane (10) bonded to the RFID label (500). The RFID label is characterized in that the laser hologram membrane (10) is provided with a metal reflecting layer (103) with two symmetrical parts which have a narrow gap in between or are separated by a non magnetic insulation material strip to be insulated with each other. The narrow gap or the non magnetic insulation material strip is arranged on the central axis of the RFID label (500). The RFID label removes the shields from the metal reflecting layer of the laser hologram membrane against electromagnetic waves by separating the metal reflecting layer of the laser hologram membrane into two symmetrical parts, removes the effects caused by the laser hologram membrane on antenna impedance by improving designs of antennas, has no limit on the size of the laser hologram membrane, and increases the radiation of the antennas and the read-distance of the RFID label.
