寄生分形多三角形结构在多频天线领域的应用推广

The Application and Popularization of the Triangular Shaped Fractal Parasitic Elements in Multi-band Antenna Field

将寄生分形多三角形结构(Triangular Shaped Fractal Parasitic Elements,TSFPE)进行了改进和应用推广,提出一种基于TSFPE的新型双频段振子天线,其具体结构为在振子天线的顶端两边对称地加载多个分形三角形。振子天线两臂控制低频段的辐射,而所加载的TSFPE控制高频段的辐射。仿真和实测结果表明,天线在两个频段都具有良好的性能。新型天线结构的研制成功丰富了多频天线的种类,验证了TSFPE在多频天线领域应用推广的可行性。该研究还将为TSFPE在多频天线领域的进一步应用推广提供参考。

In this paper,the triangular shaped fractal parasitic elements( TSFPE) is modified and generalized. Based on the TSFPE,a novel dual-band dipole antenna is proposed. The dual-band is realized by incorporating TSFPE in front of arms of dipole. The first and second band is realized by arms of dipole and the TSFPE respectively. Both simulation and experiment shows that the proposed antenna has good performance. Through the development of the novel antenna,the kinds of multi-band antenna are enriched and the feasibility of popularizating the TSFPE in multi-band antenna field is preliminary verified. Our study will provide reference for the further application of the TSFPE in multi-band antenna field.
