| 摘 要： | 综合多种技术,提出了一种宽频带小型化的三频PIFA天线。基于缝隙加载技术,在辐射贴片上开双L形槽以形成多个电流路径,从而产生多个谐振频率;引入折叠的辐射片结构以缩小天线的轮廓;通过较宽的馈电带片激励来展开天线各个频段的带宽。天线的仿真与测试结果吻合较好,证实了该新型天线具有较宽的工作频带和良好的辐射特性,能较好地满足GSM/DCS/ISM三个频段的要求,还覆盖了S-DMB频段,具有一定的实用价值。

| Abstract: | A broadband and small tri-band planar inverted-F antenna is proposed in this paper.Based on slot-loading,multiple current paths can be generated with two L-shaped slots etched in the radiation patch,resulting in multiple resonant frequencies.Besides,antenna's size is greatly reduced by introducing the folded structure.In addition,the antenna band can be broadened to a large extent when excited by a wide feed sheet.The measured results are in well agreement with the simulation results.Both of them show that ... |
