| 摘 要： | 设计了一种三角形嵌套结构的具有四个频带的多频天线,该天线由三个三角形金属环和一个三角形金属片形成的辐射单元嵌套构成,四个单元共用一个顶点,可通过共面波导进行馈电。应用电磁仿真软件CST进行仿真分析,结果表明多频天线的频带个数、中心频点和带宽是由嵌套三角形的个数、高度和顶角角度控制,且各频点与相应单元的高度之间具有一致的规律。仿真设计了2.4GHz、3.5GHz、5.2GHz和5.8GHz四个频带的多频三角形分形嵌套单极印刷天线,并制作了天线实物进行实验验证。研究表明,三角形分形嵌套天线通频带可控性良好,且尺寸较小,易于制造,可广泛应用于WLAN/WiMAX等领域。

| Abstract: | A multi-band antenna with triangle-nested construction is proposed and designed,which can operate in four bands.The antenna is nested by four radiator units,including three triangle metal-rings and a triangle metal-patch.The four units have a common vertex,which can be fed by coplanar waveguide.The proposed antenna model has been simulated and analyzed by CST.The simulated results present that the number of multi-band,the central frequency and bandwidth can be controlled by the number and height of triangle... |
