Abstract:

To meet the engineering requirement, a 2.45GHz RFID tag antenna and its minimization design are described. The antenna is presented with 450MHz bandwidth under the condition of VSWR less than 1.5, 1.4dB gain, and with the dimension of 37mm×45.8mm. After the minimization, the antenna shows a dimension of 31.8 mm×28.5mm, around 47% reduction of area compared to the original one. Its bandwidth is about 220MHz under the condition of VSWR less than 1.5, and 1.2dB gain. The measured results are compared with the simulated results, and good agreement is obtained.

Key words: RFID tag antenna, printed dipole antenna, minimization
