摘要： An RFID reader antenna including: a printed circuit board (PCB) formed as a dielectric substance; a plurality of slot groups, each having a plurality of slots, disposed on a first face of the PCB; a ground face disposed on areas, excluding the plurality of slot groups, of the first face of the PCB; and a feeder formed as a microstrip line with an open end on a second face of the PCB to feed the plurality of slot groups. Because the slots periodically formed on the ground face are fed in series by using the single microstrip line, the RFID reader antenna can reliably recognize a larger area with a simple structure. In particular, the RFID reader antenna can be useful for the bookstands for book management or smart shelves for displaying articles or goods including clothing goods in superstores or hypermarkets through the use of the ILT RFID application.
摘要翻译：一种RFID读取器天线，包括：形成为电介质的印刷电路板（PCB）; 多个槽组，每个具有多个槽，设置在所述PCB的第一面上; 布置在所述PCB的第一面的除了所述多个槽组之外的区域上的接地面; 以及馈送器，其形成为在PCB的第二面上具有开口端的微带线，以馈送多个槽组。由于通过使用单条微带线，周期性地形成在地面上的槽被串联馈送，因此RFID读取器天线可以以简单的结构可靠地识别较大的区域。特别地，RFID阅读器天线可用于书本管理的书店或通过使用ILT RFID应用程序来显示物品或商品，包括超级市场或大型超市中的服装商品的智能货架。
