ABOUT THE PHOTO

Passive RFID systems, consisting of readers and tags, are expected to replace bar codes as the primary means of identification, inventory and billing of everyday items. The tags typically consist of an RFID chip placed on a flexible film containing a planar antenna. The antenna captures radiation from the reader's signal to power the tag electronics, which then responds to the reader's query. The PENI Tag (Product Emitting Numbering Identification Tag) shown, developed by the University of Pittsburgh in a team led by Professor Marlin H. Mickle, integrates the antenna with the rest of the tag electronics. RFID systems involve many electomagnetics concepts, including antennas, radiation, transmission lines, and microwave circuit components. (Photo courtesy of Marlin H. Mickle.)

關於照片



被動式 RFID 系統由讀取器和標籤組成,預計將取代條碼成為識別、庫存和計費日常物品的主要手段。標籤通常由放置在柔性薄膜上的 RFID 芯片和平面天線組成。天線捕捉讀取器信號的輻射以供電標籤電子元件,然後對讀取器的查詢做出回應。圖中所示的 PENI 標籤(Product Emitting Numbering Identification Tag)由匹茲堡大學的 Marlin H. Mickle 教授領導的團隊開發,將天線與其他標籤電子元件集成在一起。RFID 系統涉及許多電磁學概念,包括天線、輻射、傳輸線和微波電路元件。(照片由 Marlin H. Mickle 提供。)
