摘要

提出了一种基于宽带天线的紧凑单极天线设计方案，适用于双陷波的三波段WLAN/WiMAX应用。通过引入一个短段负载的接地和两个蚀刻在辐射贴片上的新型回形针结构，可以实现紧凑的整体尺寸31 mm 33 mm 1 mm和三个独立的工作频段，有效覆盖2.4/5.2/5.8 GHz WLAN频段和2.5/3.5/5.5 GHz WiMAX频段。采用紧凑型回形针结构，与常用的U型槽相比，可节省约37%的尺寸面积，有效提高带缺口的形成效率。仿真和实测结果表明，该天线具有良好的类偶极子辐射特性，在工作频带内具有可观的增益。此外，研究了两种蚀刻回形针结构的主要参数，分别控制两种止动带的位置和带宽，并在此基础上对三个工作带进行独立调节。

A Printed Monopole Antenna for Triple-Band WLAN/WiMAX Applications

A new compact design of monopole antenna for triple-band WLAN/WiMAX applications with two band-notches based on broadband antenna is presented. By introducing a stub loaded ground and two new paper clip structures etched on radiation patch, a compact overall dimension 31 mm 33 mm 1 mm and three separated operating bands effectively covering 2.4/5.2/5.8 GHz WLAN bands and 2.5/3.5/5.5 GHz WiMAX bands can be achieved. Compared with familiar U type slot, the introduced compact paper clip structure can save about 37% of dimension regions, which could effectively improve efficiency of band-notch formation. Simulated and measured results demonstrate that the proposed antenna has good dipole-like radiation characteristics with appreciable gain across the operating bands. Besides, main parameters of the two etched paper clip structures are investigated to control the positions and bandwidths of the two stop-bands, respectively, on basis of which the three working bands can be adjusted independently.
