发明名称 Multiple-cavity antenna
摘要 An antenna for a Radio-Frequency IDentification (RFID) system is disclosed that comprises a resonant structure, an RFID load element, and a floating coupling element. One of the two terminals of the RFID load element is connected directly to the resonant structure, and the other terminal is connected to the floating coupling element. The floating coupling element is electrically isolated from the resonant structure; its presence provides an improved impedance match to the RFID load element.
