摘要
在某型宽带平面单脉冲天线系统的研制中,采用了多层四元微带天线阵作为馈源,运用T型功分器和威尔金森功分器设计了一个一分四路的功分器作为阵列的馈电网络,并利用商业软件HFSS对整个阵列进行了仿真和优化设计。通过实验测量,该天线阵的阻抗带宽达到了24.8%,在工作带宽内,方向图特性良好,满足了系统的设计要求。
In the development of some type of broadband planar monopulse antenna system, one microstrip antenna array of muhilayer four-unints is used as the feed source and a forth divider used as the feed network is comprised of a T-type divider and two Wilkinson dividers. Then, the simulation and optimization of the antenna array are carried out by the commercial software HFSS. Through the measurement, the antenna array has 24.8% im- pedance width and good beam pattern characteristics, which fully satisfy the design requirement of the system.
