摘要：

文中提出了一种适用于K波段的低剖面宽带宽角低副瓣圆极化稀疏相控阵天线,该天线单元的辐射部分由带有寄生环形辐射器的圆形贴片和L形贴片组成。为了与四通道T/R组件集成设计,设计了跨层连接微带传输线,并引入单元旋转技术大幅拓宽了天线的轴比带宽。此外,在考虑T/R组件引入的阵元布局制约下,设计了多约束子阵级优化布阵算法,仅通过子阵位置的优化,设计了400单元规模的宽带宽角低副瓣稀疏阵。仿真结果表明,该稀疏阵在44.6%的稀疏率下的法向增益为30.46 dB,波束宽度小于4.5°,扫描±55°内副瓣电平低于-13.13 dB,适用于K波段卫星通信相控阵天线。

Abstract:

This study presents a low profile wide band wide angle low sidelobe circular-polarized sparse phased array antenna for K band. The radiation part of the antenna unit consists of a circular patch with parasitic ring radiator and an L-shaped patch. Due to the feed port limitations of the T/R assembly, the antenna is miniaturized through the underlying microstrip cable connection metal through-hole, making the antenna easy to integrate with the internal T/R assembly. At the same time, the sequential rotation technique is applied in the antenna array to expand the axial ratio bandwidth. In addition, considering the constraints of the element layout introduced by T/R assembly, a multi-constrained subarray level optimization algorithm is designed. Only through the optimization of the subarray position, a 400-cell wide band, wide angle and low sidelobe sparse array is designed. Simulation results show that the sparse array achieves normal gain of 30.46 dB, beam width of less than 4.5° and sidelobes level of less than -13.13 dB within ±55° under the sparse ratio of 44.6%, which is suitable for K-band satellite communication phased array antenna.
