Broadband UHF RFID passive tag antenna for near-body operation

Abstract

A new improved design of a RFID passive tag antenna is presented for patient identification that is operable in the full UHF RFID (860-960 MHz) band. The antenna is based on a low profile printed solution and can be placed near the human body without sacrificing reading range. Extensive numerical simulations were performed and demonstrate that the new proposed configuration improves in relation to previous known solutions for near-body or other problematic surfaces.
