| 摘 要： | 设计了一种超宽带（ultra-wideband, UWB）定向平面天线二元阵列。两个圆形单极子天线单元通过T 型功分馈电网络组成二元阵。天线在-10dB 以下回波损耗从2.98～10.96GHz，绝对阻抗带宽为7.98GHz，倍频程为3.68。天线增益在3GHz，6GHz 和9GHz 时，分别为3.54dB,5.03dB 和5.67dB。天线最终尺寸为28.4×67 mm2, 厚度为1mm。有效实现了方向图定向性，可用于远距离地面宽带通信系统。

| Abstract: | The design of a directional ultra-wideband printed circular monopole antenna array to operate in the 3.1-10.6 GHzUWB is proposed in this paper. The two printed circular monopole antennas are fed by broadband T-junction power divider. Theantenna has an occupied bandwidth of the return loss on a -10 dB level is 7.98 GHz which is from 2.98 to 10.96 GHz, and the octaveband is 3.68. The gains are 3.54 dB at 3 GHz, 5.03 dB at 6 GHz and 5.67 dB at 9 GHz, respectively. The final size of this antennais 28.4×67 mm2, and the thickness is 1 mm. The characteristic of direction is obtained effectively, and hence the antenna can beused in the directional long-distance terrestrial broadband communications |
