Abstract :
A new planar RFID tag antenna is developed, which performs well on metallic objects. Unlike earlier attempts to resist the effect of metal with absorbing and isolating materials, this approach introduces a special structure-¿Multi-Layers¿, and the newly-invented Adaptive Comprehensive Learning Particle Swarm Optimization (A-CLPSO) is implemented in the process of the antenna design. Moreover, with specially-designed algorithms, both the radiation part and the middle ground part are continuous structure without point contact. The overall size of the optimized antenna is 70*50*4 mm3. The simulated and experiment results are shown, which meet the demand of Chinese RFID standard.
