摘要

摘要: 为了实现X波段超宽角扫描，提出一种新型的紧耦合阵列天线单元设计，并结合等效电路分析优化天线参数。采用集成式Marchand巴伦馈电，可以实现偶极子与巴伦共基板印刷，进而减小天线的重量与成本。阵列口径上方加载垂直寄生覆层及水平单层电介质板，两者共同作用以改善宽角扫描时阻抗变换。仿真结果表明该天线可实现X波段（8～12 GHz）E面80°、H面70°的扫描角，且有源驻波比小于3。该天线结构简单紧凑，易于加工制作。

Abstract: –To realize X-band ultra-wide-angle scanning, the paper proposes a novel tightly coupled array antenna unit design, and combines the equivalent circuit to analyze and optimize antenna parameters. With the integrated Marchand balun, dipole and balun can be fabricated on the same PCB, thus reducing antenna’s weight and cost. Introducing the vertical parasitic superstrate and horizontal dielectric layer above the antenna aperture, the two work together to improve the impedance transformation during wide-angle scanning. The results show that the scanning angle ranges up to 80° in E-plane while 70° in H-plane, with an active VSWR<3, in X-band (8–12 GHz). The antenna is simple, compact and easy to fabricate.
