摘要
设计了一种新型套筒单极子超宽带天线。该天线采用双套筒结构,有效展宽了天线的阻抗带宽。采用HFSS电磁仿真软件对天线进行了仿真优化,加工出实物并进行了测试,该天线在超过4：1的带宽内（0.45~1.9GHz）,驻波比均小于2.5,且具有较好的全向辐射方向图特性,并且实测值与仿真值较一致。
A novel Ultra-wideband, sleeved transmission line-fed subulate monopole antennas with double sleeves is presented. Optimization of the antenna characteristics is carried out by HFSS. while the measurements compared to the simulated results are implemented to the fabricated antenna. The antenna offers an ultrabroadband performance in the frequency band 0.45~1.9 GHz with a VSWR of less than 2.5 ： 1.
