Design, Development and Integration of Novel Antennas for Miniaturized UHF RFID Tags

An overview of design requirements and novel approaches for improved performance UHF radio frequency identification (RFID) tags is presented. Two matching techniques, an inductively coupled structure and a serial stub structure are discussed. Different miniaturized antenna topologies are proposed, focusing on low-profile, high efficiency and high directivity in very compact (less than 3 in times 3 in) configurations.
