摘　　要：在传统谢尔宾斯基(Sierpinski)毯式分形贴片天线的基础上,加上两个短路过孔,使天线能够工作于更多的频段,并且在保持天线体积不变的情况下,使天线的第一频点降低到原来的一半。对所加短路过孔的位置和直径与天线的工作频点之间的关系进行了研究。使用高频电磁仿真软件(HFSS)仿真软件给出了天线S11和方向图的仿真结果,制作了实际的天线,给出了S11实验结果。实验结果与仿真结果基本吻合。A kind of shorted Sierpinski carpet fractal microstrip antenna is proposed for multi-frequency and wide-hand communication. The high frequency structure simulator（HFSS） simulating results indicate that with two metal via holes applied in the antenna, more frequency bands can be obtained. The lowest radiation frequency of the shorted fractal antenna is decreased to almost half of the noneshorted antenna. The relation between the position of the via holes and the radiation frequency band is studied. A real shorted antenna is made. The experiment result matches with the simulating one.
