摘要
为满足电磁兼容测试系统中对天线具有大功率的需求,设计并实现出一款0.2~2.5GHz高功率超宽带双脊喇叭天线。采用两段同轴线级联的方式对同轴脊波导转换结构进行了改进。仿真及实测结果表明,该方式在有效保证天线具有超宽带特性的同时,其承受功率大于800W连续波,近场场强值大于200V/m,满足设计要求,可应用于电磁兼容辐射抗扰度测量中的大功率发射,具有较高的应用价值。
In order to meet the high-power requirements of the antenna in the electromagnetic compatibility test system, a0.2~2.5 GHz high-power ultra-wideband dual-ridge horn antenna was designed and implemented.The conversion structure of the coaxial ridge waveguide is improved by adopting the cascade connection of two coaxial lines.Simulation and actual measurement results show that this method can effectively ensure that the antenna has ultra-wideband characteristics, while its withstand power is greater than 800 W continuous wave, and the near-field field strength is greater than 200 V/m, which meets the design requirements and has high application valueinhigh-power emission of electromagnetic compatibility radiation immunity measurement.
