This article presents a UHF radio frequency identification tag antenna used in proximity to the chest of a human body for student ID card identification.The proposed tag antenna is a rectangular slot‐type patch structure printed on a PVC card. For near‐body applications, stratified square plates with physical parameters are used as a human model. The radiation properties of the slotted tag antenna placed near the model and the absorption effects due to human body are investigated. The research used the HFSS simulator to optimally design the antenna and employed the FEKO simulator to verify the simulated results. The designed tag was constructed for testing the reading range. The measured reading range achieved is around 4.2 m as the tag is put close to the chest. © 2013 Wiley Periodicals, Inc.
