摘要
为了满足宽带高功率微波辐射系统紧凑化的需求,设计了一个口径面尺寸为20 cm×20 cm的电-磁振子组合型天线,采用三维全波电磁场仿真,得到该天线在0.3~1.7 GHz 带宽内的驻波比小于3,且在此带宽内天线增益均大于2。仿真分析了该天线结构的尺寸、电流环长度以及天线开口角度对电-磁振子组合型天线阻抗带宽和增益的影响。在此基础上,给天线馈入峰值为226 kV的宽带信号,仿真得到天线的最大辐射因子为150 kV,等效峰值功率为358.8 MW,辐射效率约70.6%。仿真结果表明:组合振子天线能够满足宽带高功率微波的辐射要求,同时满足辐射系统紧凑化和高辐射效率的要求。
Abstract
To meet the demands of compactness and miniaturization of the wideband high power microwave radiation system, an electric-magnetic vibrator combined antenna with an aperture of 20 cm×20 cm is designed. By applying the 3D full wave electromagnetic field simulation tool, it is proved that the antenna voltage standing wave ratio is less than 3 and the antenna gain is larger than 2 within the bandwidth of 0.3-1.7 GHz. Meanwhile, the influences of the size of the antenna structure, the length of the current loop and the angle of the antenna aperture on the antenna impedance bandwidth and the gain are investigated. On this basis, fed by the wideband signal with a peak voltage of 226 kV for simulation, the maximum radiation factor reaches 150 kV, the equivalent radiation power reaches 358.8 MW and the radiation efficiency is 70.6%. The results indicate that the electric-magnetic vibrator combined antenna can meet the radiation requirements of the high power wideband microwave, the compactness of the radiation system and high radiation efficiency.
