摘　　要：要本文设计了1种用于强电磁防护的X波段喇叭天线,该天线可根据入射电磁波强度自适应改变天线的场路转化效率,实现场致强电磁防护功能。通过电磁仿真,低强度电磁波入射时,喇叭天线防护设计引入的损耗在X波段8~12GHz工作频段内小于0.85dB,不改变其宽带阻抗匹配特性;高强度电磁波入射时,X波段内的防护效能大于10dB,在11GHz达到峰值的防护效能24.99dB。This article designs an X-band horn antenna for strong electromagnetic protection,which can adaptively change the field path conversion efficiency of the antenna based on the intensity of the incident electromagnetic wave,achieving on-site strong electromagnetic protection function.Through electromagnetic simulation,when low intensity electromagnetic waves are incident,the loss introduced by the horn antenna protection design is less than 0.85dB in the X-band 8-12GHz operating frequency range,without changing its broadband operating characteristics;When high intensity electromagnetic waves are incident,the protective efficiency within the X-band is greater than 1odB,and the protective efficiency reaches a peak of 24.99dB at 11GHz.
