Abstract: An example system is provided. In some embodiments, the system may include a coupler. In some embodiments, the coupler may include a first ground layer. In some embodiments, the coupler may include a conductive layer. In some embodiments, the conductive layer is substantially infinite shaped. In some embodiments, the coupler may include a first dielectric layer positioned between the first ground layer and the conductive layer. In some embodiments, the coupler may include a second ground layer having an aperture. In some embodiments, the coupler may include a second dielectric layer positioned between the conductive layer and the second ground layer. In some embodiments, the system may include a feed path configured to transport a plurality of radio frequency identification transponders through a defined region proximate the coupler. In some embodiments, the system may include a controller.

Abstract: Various embodiments illustrated herein disclose a radio-frequency identification (RFID) reader having a first RFID tag having a first antenna element operating at a first transmit power. The first RFID tag receives, in a first time interval, a first interrogation command from a first RFID reader through the first antenna element. The first RFID tag transmits, in the first time interval, a first response signal to the first RFID reader. The RFID reader comprises a second antenna element that operates at a second transmit power and a processor communicatively coupled to the second antenna element. The processor transmits, in the first time interval, a second interrogation command to one or more second RFID tags through the second antenna element. The first RFID tag transmits, in a second time interval, a third interrogation command to a first RFID tag of a second RFID reader through the first antenna element.
