【摘要】 提出一种新型的三频平面倒F天线结构。通过在矩形贴片上开双U形槽,非常容易获得三频特性,而且可以很方便地实现对三个谐振频率的单独调节。文中设计了一个工作在GSM/DCS/ISM三个频段的平面倒F天线,采用基于矩量法的IE3D软件进行建模、仿真和分析,实测结果与仿真结果相当吻合。此外,由于这种天线只用一个同轴探针馈电,尺寸小并且结构简单,因而容易设计、制作和调节。更多还原

【Abstract】 In this paper,a novel triple-band PIFA structure has been proposed.By etching two U-shaped slots in a rectangular patch,the triple-band character can be obtained easily.The triple resonant frequencies can be tuned independently by changing corresponding parameters.An antenna for GSM/DCS/ISM has been presented.The designed antenna is simulated by IE3D software and agrees quite well with the experimental result.Additionally,the proposed PIFA only uses a single feed,and has a compact profile and simple structure.Hence it is easy to design,manufacture and adjust.更多还原
