摘要
提出了一种倒F型平面印刷结构的双频天线,其PCB尺寸为20mm(长)×13mm(宽)×1.5mm(厚)。天线工作于2.3—2.49GHz和5.14—5.84GHz频段,带内驻波小于2.0,水平面方向图呈全向辐射性能,适用于WLAN系统应用。仿真设计在综合考虑天线主要结构参数对阻抗特性的影响之后,加工了天线实物并在不同的应用环境条件下进行实测。数据表明,实验结果与仿真结果一致,最终的天线具有结构简单、易于加工、方便集成的特点。
A dual-band inverted-F planar printed antenna is presented in this paper. The size of the antenna is 20mm（height）×13mm（width） ＆#215; 1.5mm（thickness）. It operating frequency range is 2.3-2.49GHz and 5.14-5.84GHz and its in-band voltage standing wave ratio （VSWR） is less than 2.0. Its horizontal pattern is suitable for WLAN applications because it has omni-directional radiation pattern. Fully considering the influences of structure parameters and impedance characteristics in simulation, the antenna in-kind is produced and tested in different application conditions. Data demonstrate that experimental results accord with the simulation results and the antenna has the features of simple structure, convenient production and integration.
