标签用贴片天线及使用该贴片天线的RFID用标签
摘要：
本发明的目的在于提供一种即使附设在包含液体的物体或金属上，也不劣化通信距离且简便而便宜的结构的标签用贴片天线及使用该贴片天线的RFID用标签。标签用天线(3)构成为包括：隙缝(5)，其沿着天线图案的边缘的一部分(6a、6b)形成于该边缘的附近；以及馈电点，其对由于该隙缝(5)而与所述天线图案(3)的主体相隔该隙缝(5)的宽度的、上述边缘的一部分(6)的中间部分切开而形成，用于向标签用LSI供电。标签用贴片天线(3)和连接在上述馈电点上的标签用LSI(4)通过PET等的树脂体(2b)模塑为卡状，进而通过粘合剂(9)粘合在作为电介质的市场上出售的通用脂基板(7)上，并且在通用脂基板(7)的粘合面的相反面上粘附有导体膜(8)。
摘要（英）：

A patch antenna for tag is provided. The communication distance of the patch antenna is not impaired even if the patch antenna is attached to an object or a metal containing liquid, and is provided with a convenient and low cost structure. A tag for RFID employing the patch antenna is also provided. The patch antenna (3) for tag comprises a slit (5) formed in the vicinity of the edge of an antenna pattern along a portion (6a, 6b) thereof, and a feeding point to an LSI for tag formed by cutting the middle part of a portion (6) of the edge spaced apart from the body of the antenna pattern (3) by the width of the slit (5). The patch antenna (3) for tag and the LSI (4) for tag connected with the feeding point are molded of a resin body (2b) such as PET into card-shape and bonded to a general purpose resin substrate (7) available on the market as a dielectric through adhesive (9), and a conductive film (8) is applied to the side of the general purpose resin substrate (7) opposite to the adhesive surface.
