The Behavior of CPW-Fed Sierpinski Curve Fractal Antenna

Abstract In this paper, the behavior of Coplanar Waveguide (CPW) fed SIERPINSKI curve fractal antenna is studied. The results show that there is a relationship between the iteration number and the resonance frequencies. With increase in the number of iteration the resonance frequency decreases with a constant ratio. The use of fractal structures to design antennas makes them more miniaturized. The simulated results obtained from CADFEKO a Method of Moments (MoM) model based Solver and measurement using Vector Network Analyzer Anritsu MS2026C are in good agreement.

摘要 本文研究了共面波导（Coplanar Waveguide, CPW）馈电的谢尔宾斯基曲线分形天线的性能。研究结果表明，迭代次数与谐振频率之间存在明确关联：随着迭代次数增加，谐振频率以恒定比例降低。采用分形结构设计天线可有效实现天线小型化。基于矩量法（Method of Moments, MoM）求解器的CADFEKO仿真结果，与使用安立MS2026C型矢量网络分析仪的实测结果具有良好的一致性。
