Methods to Improve Performance of RFID Antenna Used for E-Commerce

Abstract:

Firstly, this article focous on the requirements for RFID antenna of ecommerce--a fractal design of folded dipole antenna by moment method for simulation analysis of the designed antenna, the return loss performance of the antenna are calculated. In order to have more redundancy for the performance of the antennas in actual use when in all kinds of bad environment to function properly, we try to use methods of additional passive patch, microcosmic fractal structure and mirror compensation structure to improve the performance of the antenna. Then we compare the effects of multiple antenna performance improvement methods, and find the best optimization design project. According to the design of antenna, it’s resonant frequency is 2.4GHz, the minimum return loss value is -46.27dB, the bandwidth is 544MHz. Secondly, in view of the engineered practice, the article also discusses the influence of substrate parameters on the performance of the antenna in detail.
