Description

多馈入超高频RFID标签天线
技术领域
本发明涉及天线领域，尤其涉及一种多馈入超高频RFID标签天线。
背景技术
RFID(Radio Frequency Identification，射频识别)是一种通过无线射频方式进行非接触式的双向数据通信，从而对目标进行识别的技术。RFID***通常由读写器和电子标签组成。电子标签包括天线及标签芯片，通过天线发射或接收电磁波与读写器进行数据交换，从而实现电子标签的识别。现有的超高频RFID天线通常都只包括一个馈入点，当标签芯片故障时，单馈入RFID天线无法正常工作；或当标签天线需要支持多种标准的频段时，单馈入RFID天线无法满足用户的需求。
发明内容
有鉴于此，有必要提供一种多馈入超高频RFID标签天线，以解决上述技术问题。
本发明提供一种多馈入超高频RFID标签天线，该标签天线包括一天线结构、一基板及一接地面，该基板位于该接地面的上方，该天线结构与该接地面连通，该天线结构包括一辐射单元、多条微带线及多个标签芯片，其中，每两条微带线之间连接一标签芯片，从而形成一微带馈电回路。
相较于现有技术，本发明提供的多馈入超高频RFID标签天线包括多个标签芯片，当标签芯片相同，其中一个标签芯片故障时，该RFID标签天线仍能够正常工作，保证应用该标签天线的标签能正常进行识别。当标签天线具有不同的工作频段时，应用该标签天线的标签可在不同国家或地区进行识别。

如下具体实施方式将结合上述附图进一步说明本发明。
具体实施方式
请参考图1，其示出了本发明第一实施方式中的多馈入超高频RFID标签天线1。请一并参考图2，该标签天线1包括一天线结构10、一基板20及一接地面30。在本实施方式中，该天线结构10位于该基板20的上方，该基板20位于该接地面30的上方，该天线结构10还与该接地面30连通。
如图1及图2所示，该天线结构10包括辐射单元101、第一微带线102、第二微带线103、第三微带线104、第四微带线105、第一标签芯片106及第二标签芯片107。其中，该第一标签芯片106连接于该第一微带线102及该第二微带线103之间，该第二标签芯片107连接于该第三微带线104及该第四微带线105之间，从而形成两条微带馈电回路。
在本实施方式中，该第一微带线102通过一第一导柱108与该接地面30连通，该第二微带线103通过一第二导柱109与该接地面30连通，该第三微带线104通过一第三导柱110与该接地面30连通，该第四微带线105通过一第四导柱111与该接地面30连通，从而使得该天线结构10与该接地面30连通。其中，该第一导柱108、第二导柱109、第三导柱110及第四导柱111可开路或短路。
在本实施方式中，该辐射单元101为一矩形的辐射面，该第一微带线102、第二微带线103及该第一标签芯片106位于该辐射单元101的侧边L1附近，该第三微带线104、第四微带线105及该第二标签芯片107位于该辐射单元101的与该侧边L1相邻的侧边L2附近。该第一微带线102、第二微带线103及该第一标签芯片106形成的微带馈电回路与该第三微带线104、第四微带线105及该第二标签芯片107形成的微带馈电回路分别设置于该辐射单元101相邻的两条侧边附近可提高该标签天线1的隔离度。
请参考图3，在一第二实施方式中，该第一微带线102、第二微带线103及该第一标签芯片106位于该辐射单元101的侧边L1附近，该第三微带线104、第四微带线105及该第二标签芯片107也可位于该辐射单元101的与该侧边L1相对的侧边L3附近。此时，该第一微带线102、第二微带线103及该第一标签芯片106形成的微带馈电回路与该第三微带线104、第四微带线105及该第二标签芯片107形成的微带馈电回路分别设置于该辐射单元101相对的两条侧边附近。
可选地，在上述的两个实施方式中，该第一标签芯片106及第二标签芯片107为相同的两个标签芯片，当其中一个标签芯片故障时，应用该标签天线1的标签仍然可以通过另一标签芯片进行识别。
可选地，在上述的两个实施方式中，该第一标签芯片106及第二标签芯片107具有不同的工作频段，从而符合不同国家或地区的RFID设备的频段标准，使得应用该标签天线1的标签可在不同国家或地区进行识别。
请参考图4，在一第三实施方式中，该辐射单元101也为一矩形的辐射面，该天线结构10包括辐射单元101、两条第一微带线102、两条第二微带线103、两条第三微带线104、两条第四微带线105、两个第一标签芯片106及两个第二标签芯片107。其中，该两个第一标签芯片106分别连接于一第一微带线102及一第二微带线103之间，该两个第二标签芯片107分别连接于一第三微带线104及一第四微带线105之间，从而形成四条微带馈电回路。
在本实施方式中，每一标签芯片位于该辐射单元101的一条侧边附近。其中，该两个第一标签芯片106设置于该辐射单元101相对的两个侧边附近，该两个第二标签芯片107设置于该辐射单元101的另两个相对的侧边附近，该第一标签芯片106及该第二标签芯片107具有不同的工作频段。
在本实施方式中，由于设置有两个相同的第一标签芯片106及两个相同的第二标签芯片107，当其中一第一标签芯片106或第二标签芯片107故障时，应用该标签天线1的标签可通过相同的另一标签芯片进行识别。由于该第一标签芯片106及第二标签芯片107具有不同的工作频段，从而符合不同国家或地区的RFID设备的频段标准，使得应用该标签天线1的标签还可在不同国家或地区进行识别。
最后应说明的是，以上实施例仅用以说明本发明的实施方案而非限制，尽管参照较佳实施例对本发明进行了详细说明，本领域的普通技术人员应当理解，可以对本发明的技术方案进行修改或者等同替换，而不脱离本发明技术方案的精神和范围。
