摘要
对微带天线频带的展宽方法进行了研究,借助于时域有限差分法进行数值计算.经过反复修改设计,选择了在接地板“开窗”的方法,并且贴片设计为“U”型结构.对天线的散射参数、方向图等参数进行了仿真分析;用聚四氟乙烯玻璃漆布敷铜板作为原材料、对天线进行了实际制作;用AV3616XA射频微波网络分析系统对天线进行了测试.均得到了较好的结果,相对带宽达到了27%.
Microstrip antennas bandwidth enhancement method is studied, and calcutation is made for the process by using finite-different time-domain （FDTD） method. Through revision and design, opening the window method was chosen for ground plate and metal patch shape was designed U-model constitution, and antenna scattering parameter and radiation pattern were simulated and analyzed. Besides, the antenna is tested by AV3616XA RF network analyzer and good results are acquired with 27% relative bandwidth.
