商品描述
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關於將取代條碼的重要新技術的窗口，這項技術注定會改變物流和產品數據處理的面貌。在過去的二十年中，無線射頻識別（RFID）迅速發展，通過沃爾瑪（Wal-Mart）、K-Mart和美國國防部等關鍵用戶的採用，RFID已加速進入主流市場。由於其靈活性、能在視線之外運作的能力以及高數據承載能力，RFID擁有許多潛在應用。然而，儘管對2018年市場價值達250億美元的樂觀預測，潛在用戶仍然對成本和投資回報感到擔憂。本書清楚地展示了對於一種完全可列印的無晶片RFID標籤以及一個強大且高效的讀取器以整合標籤數據的需求，接著描述了這兩者。書中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負載單極天線和不對稱耦合螺旋多諧振器製作無晶片RFID標籤。該標籤通過“光譜簽名”技術編碼數據，並且目前已進入第三代版本，配備在5至10.7GHz範圍內運作的超寬頻（UWB）讀取器。
