Abstract

An ultra-wideband (UWB) combined antenna for high-power microwave (HPM) application is designed in this paper. Tapered-slot balun is adopted to enhance the power capacity. In order to realize the smooth impedance variation from the feeder to the free space and improve the radiation efficiency and percentage bandwidth (PBW), principles of exponential taper, triangular taper and Klopfenstein taper are analyzed. The results of combined antennas with three types of impedance tapered structures are compared. Also, the size of magnetic dipole is optimized by adjustable plate to improve the low-frequency performance. Finally, a high-power ultra-wideband (HP-UWB) combined antenna with length of 300 mm is designed and simulated. With excitation of the high-power bipolar pulse whose amplitude is 125 kV, width is 2.7 ns and center frequency is 268 MHz, the weighted radiation efficiency of the antenna is 82.6%, while PBW is 146.9%. The power capacity of the antenna can reach to 200 MW.

大功率微波超宽带组合天线的设计与仿真

设计了一种用于大功率微波应用的超宽带(UWB)组合天线。采用锥形槽平衡器，提高功率容量。为了实现从馈线到自由空间的平滑阻抗变化，提高辐射效率和百分比带宽(PBW)，分析了指数锥度、三角形锥度和克洛芬斯坦锥度的原理。比较了三种阻抗变细结构组合天线的性能。同时，采用可调板优化磁偶极子的尺寸，提高了低频性能。最后，设计并仿真了一种长度为300mm的大功率超宽带(HP-UWB)组合天线。在幅值为125 kV、宽度为2.7 ns、中心频率为268 MHz的高功率双极脉冲激励下，天线的加权辐射效率为82.6%，PBW为146.9%。天线的功率容量可达200mw。
