本文在多功能可重构像素天线（RPA）单元的基础上，提出了一种具有复合可重构性的线性稀疏阵列。它具有波束扫描增益波动小、两正交面旁瓣低、极化可重构等潜在优势。具体而言，首先设计了一种由驱动贴片和寄生像元组成的具有同步极化和方向重建能力的RPA，该RPA可以在x波段具有两个圆偏振的可操纵波束方向下工作。采用交叉槽耦合进给，提高极化重构能力，降低混合重构拓扑优化的复杂度。然后，将这些rpa集成到线性稀疏阵列中，实现了两个圆偏振的重构和xoz平面和yoz平面的波束导向。仿真结果表明，该相控阵在波束扫描时的增益波动和旁瓣电平都比以前的相控阵有明显的优势，并且避免了天线光栅瓣的产生。此外，还制作了RPA元件和RPA阵列原型，并对其进行了测试。仿真结果与实测结果吻合较好，表明了所提出的线性稀疏阵列在现代无线通信系统中的应用潜力。
In this paper, on the basis of multifunctional reconfigurable pixel antenna (RPA) elements, a novel linear sparse array with an attractive compound reconfigurability is presented. It has the potential advantages of its beam scanning with low gain fluctuation, low sidelobe in two orthogonal planes, and polarization reconfigurable performance. Specifically, an RPA with simultaneous polarization and pattern reconstruction capabilities, consisting of the driven patch and the parasitic pixels on the same layer of dielectric substrate, is firstly designed, which can work in several operation modes corresponding to steerable beam directions with two circular polarizations in X-band. Cross-slot coupling feed is used to improve polarization reconstruction capability and reduce the complexity of hybrid reconstruction topology optimization. Then, those RPAs are integrated into the linear sparse array to realize the reconfiguration of two circular polarizations and beam steering in xoz- and yoz-plane. Simulation results show that the gain fluctuation and sidelobe level of the array during beam scanning have significant advantages over the previous phased array, and the generation of antenna grating lobes is avoided. Moreover, both RPA element and RPA array prototypes have been fabricated and measured to testify the efficiency. The measured results agree well with the simulated ones, which indicates the application potential in the field of modern wireless communication system of the proposed linear sparse array.
