|
Abstract:
本文提出一种L频段低剖面有源相控阵天线，天线阵面采用微带缝隙天线和二次圆极化布阵技术，降低阵面高度，提高天线轴比性能。天线有源链路采用平面布局和高密度一体化集成技术降低整机高度。天线整机高度 < 43 mm，比同等性能的砖式相控阵天线高度降低41%，实现了相控阵天线低成本、低剖面的设计目标。
This article presents an L-band low profile active phased array antenna system. The antenna array adopts microstrip slot antenna form and secondary circular polarization array technology to reduce the height of the antenna system and improve the axial ratio (AR) performance. The antenna active links are integrated into one module using the planar layout and high-density integration technology. The maximum height dimension of the antenna system is lower than 43 mm. It reduced the height by 41% compared to brick phased array antennas with equivalent performance and achieved the low cost-low profile design of the antenna system.
