	本文提出了一种基于改进型的微带振子型宽带宽角扫描天线。该宽带宽角扫描天线具有频带宽、体积小、结构简单等特点。使用Ansoft HFSS软件建模、仿真和优化，该天线在2.7~3.5 GHz范围内电压驻波比小于2.5，在2~4GHz范围内天线电压驻波比除少数频点的个别扫描角外，驻波比小于3.5，绝对工作带宽达到2 GHz。该天线可广泛适用于大规模相控阵雷达领域。<br />
In this paper, a wide-band wide-angle scanning antenna based on improved microstrip dipole type is presented. The wide-band wide-angle scanning antenna has some advantages as wideband, small volume, simple structure and so on. An soft HFSS is used to model, simulate and optimize the antenna. The simulation results show that the VSWR is less than 2.5 from 2.7 - 3.5 GHz, and the VSWR is less than 3.5 from 2 - 4 GHz excepted for a few frequency points with the absolute working bandwidth of 2 GHz. The antenna may be widely used in the field of large-scale phased array radar.
