摘　　要：为了满足现代无线通信系统对小型超宽带天线的需求,提出了一种小型的超宽带单极子缝隙天线,天线印刷在0.4 mm厚的FR4介质基板上,尺寸为25.5×24 mm2。该天线的辐射单元为矩形辐射贴片,馈电线两侧有两个对称的C形寄生贴片,地面开有四个矩形凹槽和一个Φ形凹槽,辐射贴片与地面通过同轴馈线连接。利用HFSS2022软件对天线进行仿真优化,天线带宽为3~10.8 GHz,具有良好的带宽特性。In order to meet the demand of modern wireless communication systems for small ultra wideband monopole slot antenna,this paper proposes a coaxial fed miniaturized ultra wideband antenna,which is printed on a 0.4 mm thick FR4 dielectric substrate with a size of 25.5×24 mm^(2).The radiation unit of this antenna is a rectangular radiation patch,with two symmetrical C-shaped parasitic patches on both sides of the feed wire.There are four rectangular grooves and Φ-shaped groove on the ground,and radiation patch are connected to the ground through coaxial feeders.This paper uses HFSS2022 software to simulate and optimize the antenna,which has a bandwidth of 3~10.8 GHz and good bandwidth characteristics.
