| 摘 要： | 为了有效地对超宽带天线进行小型化,通过对平面椭圆单极子超宽带天线进行切半和切边处理,设计了尺寸为10mm×17mm的小型超宽带天线。为了改善因对天线进行切半而恶化的全向辐射特性,在小型超宽带天线的辐射体中引入了缝隙结构。仿真结果表明:改进的小型超宽带天线在整个超宽带频带内具有良好的阻抗匹配和全向辐射特性。该天线的测量结果与仿真结果基本吻合。

| Abstract: | A compact ultra wideband antenna with the size of 10mm-17mm is designed by half cutting and trimming the planar elliptical monopole ultra wideband antenna. A notch structure is placed in the radiator, to improve the omni-directional radiation pattern of the proposed antenna. The simulated results show that the improved antenna has good impedance match and omni-directional radiation pattern, over the whole ultra wideband frequency band. The measured results are closed with the simulated results very well. |

| Keywords: | ultra wideband (UWB) antenna monopole antenna miniaturization impedance match omni-directional radiation pattern |
