US 12,738,621 B2 · Infinite shaped coupler

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.
