The　present　invention　discloses　a　multi　slot　compact　UHF　RFID　tag　antenna　model　suitable　for　double-side　anti　metal.　This　design　achieves　precise　adjustment　of　tag　resonance　frequency　by　creating　multiple　grooves　on　the　top　and　bottom　of　this　tag,　while　maintaining　a　compact　physical　size　(40mm　×　28mm　×　3.2mm),　making　it　easy　to　use　in　various　environments.　In　addition,　the　tag　design　also　solves　the　problem　of　reading　difficulties　that　traditional　RFID　tags　may　encounter　when　attached　to　metal　surfaces.　Even　on　the　metal　surface,　the　chip　and　antenna　can　maintain　good　impedance　matching,　ensuring　stable　reading　distances　of　at　least　6　meters　and　5.6　meters　can　be　achieved　even　on　a　200mm　×　200mm　metal　plate　with　a　transmission　power　of　4W　EIRP.　©　2024　IEEE.
