摘要
设计了一种新颖小型共面波导馈电的喇叭形超宽带天线,接地面不同于传统矩形而采用接地面围绕辐射体两侧向顶部延伸的方式,并且靠近馈线的接地面使用两阶阶梯凹槽,利用仿真软件仿真优化辐射体和接地面的结构参数,天线加工后的尺寸为27 mm×30 mm×1.6 mm,实测阻抗带宽为2.5～12.0 GHz,在3.1～10.6 GHz范围内基本呈全向性,并且具有较稳定的增益,约为2.5 ～ 6.0 dBi.
A novel CPW-fed compact UWB horn shape monopole antenna is proposed. The ground is extended toward two sides of the radiator different from the traditional solid rectangle, and the ground is two stair shaped close the feed line. Simulation software is used to analyze and optimize the structure parameters of the radiator and ground, the antenna size is 27 mm × 30 mm× 1.6 mm. Measured results show impedance bandwidth is 2. 8 ~ 12. 0 GHz, and the proposed antenna is nearly omni-direction over the oper- ating bandwidth, and also has stable gain about 2. 5 ~ 6. 0 dBi.
