摘要
利用HFSS v12软件设计了一种太阳能电池作为天线辐射体的RFID电子标签天线.利用太阳能电池的射频特性,将太阳能电池作为天线的辐射贴片.因此太阳能电池既可以提供能源,也可以发送和接收电磁波;提出的天线为多层结构,采用H形缝隙耦合馈电方式,可以较容易实现宽频谐振以及天线与芯片的阻抗匹配;给出了该天线的仿真结果,仿真结果表明天线性能良好,满足RFID应用要求.
The RFID tag antenna with integrated solar cells as antenna radiator is designed by software HFSS v12. Using the RFID properties of the solar cells, the radiating patch element of a planar antenna is replaced by a solar cell. The original feature of a solar cell remains, but additionally the cell is now able to receive and transmit electromag- netic waves. The structure with multiple layers and H-shaped aperture coupled is used to achieve broadband as well as the match between the antenna and chip. Simulations are given to verify present design, and the results show that the designed antenna with good performance is satisfied for RFID application.
