RFID tag antenna based temperature sensing [PDF]
2010 IEEE International Conference on RFID (IEEE RFID 2010), 2010 Temperature monitoring is important in a number of fields, particularly cold supply chain applications. Most commercial wireless temperature sensors consist of transceivers, memory and batteries to maintain a temperature time history but this is expensive and allows for limited sensor deployment.

IEICE Communications Society Magazine, 2008 近年のRFID（Radio Frequency Identification）システムの急速な普及には目覚ましいものがある．使用されているアンテナは，システム全体の中で最も設計が難しいといっても過言ではない．これはアンテナの設計パラメータが，形状，材質，ICとのインピーダンス整合，通信エリアや各種規制等の遵守等々と非常に多岐にわたるためである．RFIDシステム（以下RFID）には使用する周波数帯がいくつか用意されており，13.56MHz帯とUHF帯（860～960MHz），2.45GHz帯等では，動作原理が異なるため，使用するアンテナの種類が異なる．また，RFIDタグを貼り付ける物質（金属や高誘電体等）によっても，アンテナ特性が大きく変化する．本論文では，RFIDタグ用アンテナの設計について述べる．
