Abstract
An RFID device (10) is provided. The RFID device (10) includes a first loop antenna (14) embedded in a device body (12), and a second loop antenna (16) embedded in the device body (12). The first loop antenna (14) and the second loop antenna (16) partially overlap each other by a set distance (d). This results in a suppression of a cross-coupling between the first loop antenna (14) and the second loop antenna (16), and allows for an optimum use of the space that is available for the antennas on the device body (12). In this manner, a reliable operation of the two antennas within desired communication ranges can be obtained.
Claims16
An RFID device comprising:
- a device body;
- a first loop antenna embedded in the device body, the first loop antenna extending in a first plane;
- and
- a second loop antenna embedded in the device body, wherein the second loop antenna partially overlaps the first loop antenna when viewed in a direction perpendicular to the first plane.
