Abstract

This letter presents the design of a patch antenna array to radiate relatively uniform fields in the near-zone of array aperture for radio frequency identification (RFID) applications. This design allows one to define a target zone for RFID tag detections as interested in the department store management system and reduces the interferences resulted from the scatters outside this target zone. The design procedure is presented with both simulations and experimental measurements examined to validate the concept.
