采用两点格式法构造了一种新型的分形结构,并利用其设计了微带分形贴片天线.采用Ansoft HFSS软件对天线进行仿真优化,然后制作了实物并完成实验测量.仿真结果和测量数据表明:一阶和二阶微带分形贴片天线的面积尺寸较传统微带贴片天线分别能够缩减46.85%和60.01%,这与传统的Koch微带分形贴片天线和Minkowski微带分形贴片天线比较,具有良好的尺寸缩减性.因此,该结构在天线小型化领域具有研究价值.

The technique of two points is introduced to construct a novel fractal structure, and the microstrip fractal patch antennas which use the fractal structure are simulated and optimized by Ansoft HFSS, then two fractal antennas are fabricated and measured. The characteristics of the fractal antennas are demonstrated by simulation results and experimental data which show that the size of 1st order and 2nd order antenna is 46.85% and 60.01% smaller than a conventional square patch antenna respectively.The two antennas have compact structure compared to the Koch and Minkowski fractal patch antennas. So the structure has important research value in compact antenna field.
