This vital new resource offers engineers and researchers a window on important new technology that will supersede the barcode and is destined to change the face of logistics and product data handling. In the last two decades, radio-frequency identification has grown fast, with accelerated take-up of RFID into the mainstream through its adoption by key users such as Wal-Mart, K-Mart and the US Department of Defense. RFID has many potential applications due to its flexibility, capability to operate out of line of sight, and its high data-carrying capacity. Yet despite optimistic projections of a market worth $25 billion by 2018, potential users are concerned about costs and investment returns. Clearly demonstrating the need for a fully printable chipless RFID tag as well as a powerful and efficient reader to assimilate the tag’s data, this book moves on to describe both. Introducing the general concepts in the field including technical data, it then describes how a chipless RFID tag can be made using a planar disc-loaded monopole antenna and an asymmetrical coupled spiral multi-resonator. The tag encodes data via the “spectral signature” technique and is now in its third-generation version with an ultra-wide band (UWB) reader operating at between 5 and 10.7GHz.
商品描述(中文翻譯)
這本重要的新資源為工程師和研究人員提供了一個窗口，讓他們了解將取代條碼並改變物流和產品數據處理面貌的重要新技術。在過去的二十年中，射頻識別技術（RFID）發展迅速，通過沃爾瑪、K-Mart和美國國防部等主要用戶的採用，RFID已經進入主流。由於其靈活性、能夠在視線之外操作以及高數據傳載能力，RFID具有許多潛在應用。然而，儘管樂觀預測到2018年市場價值將達到250億美元，潛在用戶仍然關注成本和投資回報。本書清楚地展示了對於一個完全可印刷的無晶片RFID標籤以及一個強大而高效的讀取器來整合標籤數據的需求，並對兩者進行了描述。本書首先介紹了該領域的一般概念，包括技術數據，然後描述了如何使用平面圓盤載入的單極天線和非對稱耦合螺旋多諧振子製作無晶片RFID標籤。該標籤通過“光譜簽名”技術編碼數據，現在已經進入第三代版本，配備了一個在5至10.7GHz之間運行的超寬帶（UWB）讀取器。
