This paper shows the design of a novel compact Planar Inverted F antenna (PIFA) for Ultra-High Frequency (UHF) band passive radio frequency identification (RFID) tag. The antenna is designed to operate at 915 MHz frequency. Electromagnetic simulation commercial software (Ansoft HFSS) based on finite element method (FEM) was used to simulate the antenna parameters. This antenna shows good performance and the maximum reading distance of RFID tag placed using low cost substrate polyethylene terephthalate (PET) on a 10 μm thickness aluminum surface layer, with around 9.8 m, and the overall size is 46.1 × 28.58 × 6 mm3. The proposed antenna provides a valuable reference for RFID tag antenna design mounted on metal surface, and it can be widely used in UHF RFID systems. |
