| 摘 要： | 提出了一种宽带印刷套筒天线，此天线通过选择三角渐变的辐射贴片和平面的套筒结构实现了宽频带特性，在VSWR<2.5 时实测阻抗带宽可覆盖450～1150 MHz，可用于覆盖数字电视频段（470～862 MHz）。同时辐射方向图在水平面也具有良好的全向性。通过顶加载的形式有效地降低了天线的实际高度。

| Abstract: | A printed sleeve antenna with broadband is proposed in this paper. The broadband trait is achieved by graduallychanging the shape of the triangle patch and using a planar sleeves. The metrical impedance bandwidth of 450-1150MHz,in2.5:1 VSWR can cover the frequency band of DTV(470-862MHz). The almost omni-directional radiation pattern at thehorizontal plane is obtained. The height of the antenna is minished by adding a load on the top of the antenna |
