摘要： A radio frequency identification system comprises a radio-frequency identification substrate and an interrogator. In one embodiment, the radio-frequency identification substrate comprises a plurality of radio-frequency identification devices. In one embodiment, a controller on the substrate controls a first one of the plurality of radio-frequency identification devices based on a state of a second one of the plurality of radio-frequency identification devices. In one embodiment, an antenna system includes an S-shaped portion electrically coupled to an integrated circuit along a central portion of the S-shaped portion. Adjusting the parameters of the segments making up the S-shaped portion controls performance characteristics of a radio-frequency identification device.

摘要： A radio frequency identification (RFID) tag includes an antenna having a shape providing a machine-readable or human-readable code or symbol. For example, a machine-readable code may comprise a bar code, or other suitable optical code. Human-readable symbols may include, for example, text, alpha-numeric symbols, icons, or pictographs. Using human-readable antenna forms, an RFID tag may be used as a label, for example, to add a distinctive look to the tagged product, to further identify the tag or product it is attached to, or for branding the tag or attached product.
摘要翻译：射频识别（RFID）标签包括具有提供机器可读或人可读代码或符号的形状的天线。例如，机器可读代码可以包括条形码或其他合适的光学代码。人可读符号可以包括例如文本，字母数字符号，图标或象形文字。使用人类可读取的天线形式，RFID标签可以用作标签，例如，为标记的产品添加独特的外观，以进一步识别标签或附加到其上的产品，或用于标记标签或附属产品。

摘要： An RFID tag may include an antenna substrate comprising a conductive layer etched or deposited to form an antenna, and a circuit substrate comprising a conductive layer etched or deposited to form a circuit, the antenna electro-magnetically coupled to the circuit. An RFID tag may be formed from an insert substrate comprising an insulative layer between two conductive layers, one of the conductive layers etched to form an antenna and the other conductive layer etched to form a circuit. The insert substrate may be received in an envelope formed by a label substrate, which may carry a pressure sensitive adhesive.

摘要： An RF transponder comprises a transponder integrated circuit, an antenna connected to the transponder integrated circuit, and at least one parasitic element adapted to interact electrically with the antenna and thereby affect antenna impedance. The orientation of the parasitic element with respect to the antenna is selected to achieve a desired operational frequency band for the RF transponder. Specifically, the spacing between the antenna and the parasitic element is selected to achieve the desired operational frequency band. For example, a first selected spacing may enable an operational frequency band suitable for a first geographic region (e.g., the United States), a second selected spacing may enable an operational frequency band suitable for a second geographic region (e.g., Europe), and a third selected spacing may enable an operational frequency band suitable for a third geographic region (e.g., Japan).
