Abstract

In this paper, we present the design of a high-performance dual-linearly polarised broadband stacked $2 \times 2$ patch antenna array for SATCOM on-the-move applications. The antenna has been designed to operate in the $[10.7 - 14.5]$ GHz frequency range, covering both the receiving and transmitting SOTM Ku bands, namely, $[10.7 - 12.75]$ GHz and $[13.75 - 14.5]$ GHz, respectively. The array, excited with a feeding system leveraging two perpendicular corporate feeding networks, enables electronically reconfiguration of two orthogonal linear polarisations, which can be combined to synthesise other polarisation states, such as circular. The proposed design targets of robustness, reliability and simplicity have been validated through experimental characterisation, showing a good agreement when compared against full-wave electromagnetic simulations.

Ku波段移动卫星通信双偏振宽带叠片阵列设计

在本文中，我们提出了一种高性能双线性极化宽带堆叠2 × 2$ 2\ × 2$贴片天线阵列的设计，用于SATCOM移动应用。该天线设计工作在[10.7−14.5]$ [10.7-14.5]$ GHz频率范围内，涵盖接收和发射SOTM Ku频段，即：[10.7−12.75]$ [10.7-12.75]$ GHz和[13.75−14.5]$[13.75-14.5]$ GHz。该阵列由利用两个垂直的共同馈电网络的馈电系统激发，可以通过电子方式重新配置两个正交的线性极化，这些极化可以组合以合成其他极化状态，例如圆形。通过实验表征验证了所提出的鲁棒性、可靠性和简单性的设计目标，并与全波电磁仿真结果进行了比较。
