摘要： This disclosure describes a radio frequency identification (RFID) tag that includes a three-dimensional (3D) loop antenna. The 3D loop antenna includes a first conductive portion having a length and width that substantially exceed a thickness. The length and width of the first conductive portion substantially lie in a first plane. The 3D loop antenna includes a second conductive portion having a length and width that substantially exceed a thickness. The length and width of the second conductive portion substantially lie in a second plane that is substantially parallel to the first plane. An RFID circuit electrically connected to the loop antenna excites a current through the first and second conductive portions in a current loop that lies in a third plane that is not substantially parallel to the first and second planes. In some instances the third plane may be substantially perpendicular to the first and second planes.

摘要： In general, the disclosure describes an RFID tag designed such that the tag is both covert and not easily blocked from the interrogation signal by the hand or other body part of a person. In particular, the RFID tag is designed to have a long, narrow aspect that allows placement of the tag in locations on or in a book that are inconspicuous to the casual observer while extending beyond a hand of a person holding the book by the spine on or near a geometry centerline. The RFID tag includes a dipole segment and a loop segment coupled to the dipole segment. The loop segment of the modified dipole antenna provides the antenna with larger signal strength than conventional dipole antennas. Moreover, the conductive loop segment also provides improved impedance matching capabilities to allow the modified dipole antenna to match the impedance of an integrated circuit (IC) chip of the RFID tag.

摘要： This disclosure describes RFID tags designed to provide improved impedance matching capabilities. An RFID tag may include a radiating component and a tuning component located on different layers of the RFID tag. The radiating component and tuning component are located proximate to one another to provide a proximate coupling (e.g., an inductive and/or capacitive coupling). In one embodiment, at least a portion of the radiating component of a first layer overlaps at least a portion of the tuning component of a second layer, resulting in a proximate coupling. The tuning component may be used for tuning the antenna, e.g., matching an impedance of the radiating element and an IC chip electrically connected to the tuning component. Because the radiating element does not have to be designed to match impedances, the radiating element may be designed to provide better gain, polarization purity, larger radar cross section or other antenna parameters.
摘要翻译：本公开描述了设计用于提供改进的阻抗匹配能力的RFID标签。 RFID标签可以包括位于RFID标签的不同层上的辐射部件和调谐部件。辐射部件和调谐部件彼此靠近设置以提供近端耦合（例如，电感和/或电容耦合）。在一个实施例中，第一层的辐射部件的至少一部分与第二层的调谐部件的至少一部分重叠，导致紧密耦合。调谐组件可用于调谐天线，例如匹配辐射元件的阻抗和与调谐组件电连接的IC芯片。因为辐射元件不必被设计成匹配阻抗，所以辐射元件可以设计成提供更好的增益，极化纯度，更大的雷达截面或其他天线参数。
