摘要

为了实现x波段的超广角扫描，提出了一种新的紧耦合阵列天线单元设计方案，并结合等效电路分析。利用集成的Marchand balun，偶极子和balun可以印刷在同一块PCB上，从而降低了天线的重量和成本。在天线孔径上加载垂直寄生层和水平介电层，以改善天线大角度扫描时的阻抗匹配。仿真结果表明，该天线在x波段(8-12 GHz)可实现e面80°和h面70°的扫描角，有源驻波比< 3。该天线结构简单，外形低，易于加工。

Design of X-band Ultra-wide-angle Scanning Phased Array Antenna

In order to realize the ultra-wide angle scanning of X-band, a new design of tightly coupled array antenna unit is proposed, and combined with the equivalent circuit analysis. With the integrated Marchand balun, the dipole and balun can be printed on the same PCB, thereby reducing the weight and cost of the antenna. The vertical parasitic superstrate and horizontal dielectric layer are loaded on the antenna aperture to improve the impedance matching when the antenna is scanned at a large angle. The simulation results show that the antenna can achieve a scanning angle of 80° on the E-plane and 70° on the H-plane in the X-band (8–12 GHz), with acitive VSWR< 3. The antenna has a simple structure, a low profile, and is easy to process.
