摘要
提出了一种超宽带低雷达散射截面积的全金属天线。该天线采用了全金属Vivaldi作为辐射单元,通过利用一种新型的频率选择表面结构来降低工作频段内的雷达散射截面积。此频率选择表面结构由三层周期性平面结构和双层介质构成,具有超宽带、带宽可控等特性。改变金属层的开槽宽度和中间结构的宽度,可以调整频率选择表面工作频段的带宽及中心频点位置,从而实现频率带宽可调,使其可以应用于天线不同工作频段雷达散射截面积的降低。
An ultra-wideband metal antenna with low radar cross section is proposed. The antenna adopts the metal Vivaldi as the radiation element, and utilizes a new-type frequency selective surface structure to reduce the radar cross section within the working frequency band. The frequency selective surface structure is composed of three layers of periodic planar structure and double layer medium, which has the characteristics of ultra wide bandwidth and controllable bandwidth. By changing the slot width and the width of the middle layer metal structure, can adjust the working frequency bandwidth and center frequency of the frequency selec-tive surface structure, so as to realize the frequency bandwidth is adjustable, which can be used to reduce radar cross section of the antenna in different working frequencies.
