Description

射频识别织物标签
技术领域
本发明涉及根据权利要求1的前序部分的射频识别(RFID)织物标签。
背景技术
WO 02/093524A公开一种RFID织物标签，其具有安置在载体上并连接到RFID芯片的开式天线(open antenna)。该天线是偶极天线的形式，通过RFID芯片细分为两部分，并用作设计用于超高频或者微波段的工作频率的E场天线。与RFID芯片一起，该E场天线形成不适于近程的应答器。
US 2006/0043198A1描述电容地和电感地耦合RFID芯片到偶极天线(E场天线)以及耦合到环形天线(H场天线)的不同方法。这些方法似乎更不适于用在织物标签中。
发明内容
本发明的目的是改善前面提及类型的RFID织物标签，使其同样适合于短距离。
所述目的通过如权利要求1所述的RFID织物标签实现。
由于该天线具有环，RFID芯片通过熔焊、钎焊或者用导电性胶粘剂粘附接合而直接连接到环的侧面，或者，通过电容地或者电感地耦合间接连接到环的侧面，设置有RFID芯片的天线环用作H场天线，在天线环外部的天线部分用作E场天线，RFID织物标签被提供，其例如通过E场天线覆盖远至10米的远程，例如通过H场天线覆盖小于1米的近程。
例如，H场天线主要响应磁波，而E场天线主要响应电波。磁波关于电波相位偏移。在RFID织物标签的情形下，由RFID芯片和天线组成的应答器一般是被动式应答器，其只有当H波或者E波被施加到其上时才变为主动的。其从也称作束的电磁波获得其用于接收和传输的电能。
RFID织物标签的有利的改进在权利要求2-13中描述。
根据权利要求2，RFID芯片永久地连接到天线环的侧面，提供特别简单的方案。
但是，根据权利要求3，还可能安置RFID芯片在辅助载体上的导体环的末端上，至少所述导体环部分在距天线环短的距离处平行于所述天线环延伸，所述导体环电感耦合到所述天线环。根据权利要求4，还可能安置RFID芯片在辅助载体上的导体环的末端上，导体环至少在两个位置与天线重叠或者交叉，并且在距天线短的距离处与天线平行地延伸，并电感耦合到天线。
根据权利要求5，另一可能性是，天线环与天线的其它部分分离并连接到其它RFID芯片。
织物载体是织物片状结构的形式，天线紧固到该结构。为了该目的，天线可以通过利用缝纫或者缝合的方法施加到织物片状结构，例如根据权利要求9，或者，可以以导电油墨的形式印刷上，例如，根据权利要求13。但是，如果天线结合在片状结构中，如权利要求6所述，其更加有利，这能够例如通过将其针织到针织品中而实行，如权利要求7所述。但是，根据实施例，织物片状结构是编织品，在编织品的生产过程中，天线在织机上编织到编织品中，如权利要求8所述，是特别有利的。
如果当安置芯片和导体环时使用辅助载体，辅助载体可以由塑料组成，如权利要求10所述。
根据权利要求11，天线可以由金属线形成。但是，根据权利要求12，还可能由导电涂覆聚合物线形成。
上述部件以及下面的示例性实施中要求保护和描述以及根据本发明使用的部件在其大小、形状、材料的使用及其技术概念方面并不限于任何特定例外，结果，可以使用本申请的各领域中已知的选择标准，而没有限制。
附图说明
本发明的主题的其它细节、优点和特征从下面相关附图的描述中显现，其中：
图1示出具有曲折方式布置的天线和RFID芯片的第一RFID织物标签的平面视图；
图2示出从图1的纵截面II-II剖开的图1的RFID织物标签；
图3示出具有以曲折形式布置的天线、RFID芯片和连接到另一RFID芯片的单独的天线环的第二RFID织物标签的平面视图；
图4示出具有电感地连接到一个天线环的RFID芯片的第三RFID织物标签的平面视图；以及
图5示出从图4的纵截面V-V剖开的图4的RFID织物标签。
具体实施方式
图1和2示出具有织物载体2的RFID织物标签的第一示例性实施例，织物载体2由编织物制成，开式天线4以曲折的方式织入到编织物中。RFID芯片12通过连接基座14紧固到天线的环6的侧面8、10，天线的环6在中心区域中，也就是说，在天线的一半长度处单独出来。连接基座14通过例如熔接、钎焊或者通过导电性胶粘剂连接15到天线4。天线环6形成用于近程的H场天线，天线部分16，18位于天线环6的外面，用作用于远程的E场天线。
图3示出原理上类似于图1和图2地构造的另一RFID织物标签，但是天线4a的天线环6a通过中断部20，22与天线部分16a，18a分开。RFID芯片24连接到天线部分16a，18a，并通过E场覆盖远程。天线环6a的末端连接到RFID芯片12a，其响应近程H。
图4和5示出第三RFID织物标签，类似于前面的例子，其具有载体2，天线4b以曲折的方式安置在载体2中，所述天线顺次细分为用于远程E的天线部分16b，18b和用于近程H的单独出来的天线环6b。在该例子中，RFID芯片12b并不直接连接到天线4b，而是以感应的方式间接连接。为了该目的，RFID芯片12b安置在辅助载体26上，辅助载体26也具有导体环28，导体环28大致平行于天线环6b延伸。RFID芯片12b在导体环28的末端30，32通过其连接基座14连接。承载RFID芯片12b的辅助载体例如通过粘附连接或者编织到载体2上的织物袋连接到载体2，以使得导体环28平行于天线环6b，并且距天线环6b在短距离处，结果，天线4b接收到的能量感应地传输到导体环28，并在RFID芯片12b中变得有效。这都施加到E场波和H场波。
作为对根据图4和5的实施例的替代，导体环可以与天线环重叠或者交叉至少两次，并且在距天线环一定距离至少部分地平行于天线环延伸。
处于相同频率或者不同频率并且在例如1-2500MHz的范围内的波，也就是束，能够用近程H和远程E。在本发明中，重要的是，用于近程H的天线，其例如小于1米，实质上响应波的磁部分。用于远程E的天线，其例如延伸远至10米以用于被动式应答器，实质上响应关于磁部分相位偏移的波或者束的电部分。
