Abstract: A RFID tag or label comprises a RFID tag module (comprising an electronic identification circuit and a coupling means) and an antenna structure coupled to the coupling means. The RFID tag module is separate from, separable or arranged to be severable from, the antenna structure. The tag module can be placed in or on an object and the antenna structure in or on packaging material for use with the object. A patch antenna type RFID tag antenna structure has a ground plane spaced from the patch antenna so as to increase the range of the tag. The ground plane is not substantially larger than, and electrically insulated from, the patch antenna. The ground plane is flexible, so the RFID tag structure can be worn by a human, and can be incorporated into a piece of clothing. A RFID antenna structure for use with a tag reader is made flat and robust so that it can be mounted on the ground to be walked upon or driven over. A bi-directional YAGI type RFID tag antenna structure has director elements on two opposite sides so that the YAGI antenna radiates in two opposite directions. An object includes a gain increasing metallic structure for increasing the gain of a RFID tag when placed near the object so as to form a RFID tag antenna structure.

Abstract translation: RFID标签或标签包括RFID标签模块（包括电子识别电路和耦合装置）和耦合到耦合装置的天线结构。 RFID标签模块与天线结构分离，可分离或布置成可分离。 标签模块可以放置在物体中或其上，并且可以放置在与物体一起使用的包装材料中或其上的天线结构上。 贴片天线型RFID标签天线结构具有与贴片天线间隔开的接地平面，以增加标签的范围。 接地平面基本上不大于并且与贴片天线电绝缘。 地平面是灵活的，所以RFID标签结构可以被人佩戴，并且可以并入一件衣服。 与标签读取器一起使用的RFID天线结构被制成平坦且牢固的，使得其可以安装在地面上以便被行走或被驱动。 双向YAGI型RFID标签天线结构在两个相对侧具有导向元件，使得YAGI天线沿两个相反的方向辐射。 一种物体包括增加金属结构，用于当放置在物体附近时增加RFID标签的增益，从而形成RFID标签天线结构。
