摘要

利用平面等角螺旋天线和阿基米德螺旋天线的优点，设计并仿真了一种复合螺旋天线结构。利用PBG结构的同相反射和光子局域化特性，可以提高天线的辐射性能，拓宽带宽。考虑工程过程，重点研究了衬底厚度、介电常数以及hrfid标签粘贴材料对所设计天线性能的影响。我们还制作了一个天线样品并进行了测量。结果表明，该天线具有较大的性能冗余，良好的谐振频率稳定性和高介电常数环境适应性。

Composite spiral antenna with π snowflake fractal PBG structure designed for modern RFID system

Utilizing the advantages of planar equiangular spiral antennas and Archimedean spiral antennas, a composite spiral antenna structure were designed and simulated. Due to the in-phase reflection and photon localization characteristic of PBG structure, the antenna radiation performance could be improved and the bandwidth be broaden. Considering engineering processes, the influences of the substrate's thickness and dielectric constant, and also different materials on whichRFID tags to be sticked, on the performances of the designed antenna are particularly studied. We also made an antenna sample and measured it. The results show that this antenna has large performance redundancy, good resonant frequency stability and adaptability in high dielectric constant environmental.
