| 摘 要： | 设计了一种P波段小型化超宽带天线。该天线采用微带线对五边形辐射单元进行馈电,接地板上蚀刻了锯齿形边沿的矩形宽缝。通过天线参数的仿真优化,最终实现了相对带宽约95%、尺寸为0.27λ×0.17λ(λ为低频点的自由空间波长)的超宽带P波段小型化印刷天线。仿真结果表明:天线的工作频带为300.5~848.8MHz,带内回波损耗均在-10dB以下,整个频段内天线的增益均在3dBi以上,天线为全向辐射。该天线具有平面结构,形状简单,易于共形的特征。最后制作了天线样件并进行了测试,测量结果与仿真结果吻合较好。

| Abstract: | A miniaturized ultra-wideband antenna is designed in P band. The antenna is fed by a pentagon coupled feeding structure. An improved rectangular slot with saw-tooth edge is etched on the ground. The results of parameters show that the bandwidth of the designed antenna is 293.4~830.3 MHz with relative bandwidth 95% and the return loss is less than -10 dB. The size of the antenna is ( is the wavelength of the lowest frequency). The average gain is over 3dBi in the operating range and the antenna is a kind of omni antenna. The antenna is a planar construction and is simple in shape and easy in conformation. A sample antenna is fabricated and tested. The experimental results are in good agreement with the simulation results. |
