    • 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.
    • 本公开描述了包括三维(3D)环形天线的射频识别(RFID)标签。 3D环形天线包括具有基本上超过厚度的长度和宽度的第一导电部分。 第一导电部分的长度和宽度基本上位于第一平面中。 3D环形天线包括具有基本上超过厚度的长度和宽度的第二导电部分。 第二导电部分的长度和宽度基本上位于基本上平行于第一平面的第二平面中。 电连接到环形天线的RFID电路在位于不基本上平行于第一和第二平面的第三平面中的电流回路中激发通过第一和第二导电部分的电流。 在一些情况下,第三平面可以基本上垂直于第一和第二平面。
