摘　　要：设计1款基于开槽技术的低RCS宽带磁电偶极子天线。文章首先根据电流分布状态分析了开槽减缩天线RCS的原理,在此基础上设计了1款工作于X波段的磁电偶极子天线并在天线地板上开菱形槽。仿真结果表明:天线工作频段为7.03-12.80GHz,增益在9.3-12.4GHz稳定在4dBi以上,方向图在E面和H面上的拟合度高。对比未开槽天线,在8.2-11.8GHz频段范围内,RCS得到有效减缩,最大缩减32dB,同时天线保持良好辐射特性。In this paper,a low RCS broadband magnetoelectric dipole antenna based on slotting technology has been designed.The principle of the slot antenna RCS reduction from the current distribution of state,on the basis of the design of a magnetic dipole antenna operating in X-band and diamond-shaped open slot antenna on the floor.The simulation results show that the antenna operating frequency range is 7.03GHz to 12.80GHz,and the gain is stable above 4dBi from 9.3GHz to 12.4GHz.The pattern has a high degree of fit on the E and H planes.Compared to the unslotted antenna,the RCS is effectively reduced in the 8.2 GHz to 11.8 GHz band,with a maximum reduction of 32 dB,while the antenna maintains good radiation characteristics.
