ABSTRACT:
Readability of overlapping radio frequency identification (RFID) devices on overlapping objects, such as RFID labels on stacked garments, is improved by having different antenna configurations for the overlapped RFID devices. Each pair of closest overlapped RFID devices may have different respective antenna configurations. The different respective antenna configurations may be mirror images of one another, or may have the same shape, with a relative rotation between the two. The different antenna configurations may substantially fill an antenna-receiving portion that is located in the same relative location in each of the RFID devices, with the antenna-receiving portion covering most of an area of the RFID devices. Feedpoints of the different antenna configurations, for receiving a strap or interposer for coupling to the antenna configurations, may be in the same relative location.
