摘　　要：改进了一种印刷圆盘单极超宽带天线.利用仿真软件CST对其进行了仿真计算,最后给出了天线的反射损耗曲线和辐射方向图.该天线采用微带线进行馈电.天线基板采用较低的介电常数(ε=2.2),天线的-10dB反射损耗的频率覆盖范围为2.77～14.82GHz.这种天线很适合应用于目前的短程超宽带通信系统.An ultra-wideband printed circular-disc monopole antenna was developed and simulated by CST soft-ware, and in the last the reflection loss curve and the radiation patterns of this antenna were given in this paper. This antenna feeds signals with microstrip line, adopts lower dielectric constant substrate （ ε = 2.2） and has a frequency range of 2.77-14.82 GHz when the reflection loss is - 10 dB. It is suitable for the current short-range ultra-wideband communication systems.
