摘　　要：给出一种双层分形微带贴片天线,天线的馈电元和寄生元都进行了Minkowski分形处理,研究了单元分形迭代次数和凹入宽度(indentationwidth)对天线谐振频率的影响.加工并测试了试验天线,计算与实验结果吻合较好.结果表明,该新设计比常规矩形贴片天线尺寸小,并具有较宽的工作带宽和二维对称性,适合于双极化天线应用.This paper discusses a stacked fractal microstrip antenna in which both the fed patch and the parasitical patch are fractal with Minkowski islands. The effects of the fractal indentation width and the iterative generations on the antenna performance are analysized. A test fractal microstrip antenna is made and the measurement shows good agreement between the numerical calculations and the experimental results. The new design is much smaller in size than a convention rectangular patch antenna. Moreover, it has a medium bandwidth and 2D symmetry, suitable for dual-polarized antenna applications.
