这封信介绍了将Vivaldi天线集成到针对60 GHz WiGig应用的印刷电路板(PCB)上。天线制造采用了意法半导体基于玻璃基板的集成无源器件(IPD)技术。在自由空间中，辐射方向图测量表明，在56~65 GHz的端射方向上，实现的增益大于4dBI。详细研究了天线集成对印制板的影响，结果表明，天线的反射系数受到合理的干扰，但辐射方向图，特别是主波束指向方向有很大的变化。通过对Vivaldi积分时沿印刷电路板传播的表面波的分析，提出了一种新的拓扑结构，以保持端射方向的主辐射，同时提高实现增益。
The integration of a Vivaldi antenna on a printed circuit board (PCB) targeting 60-GHz WiGig applications is presented in this letter. The integrated passive device (IPD)technology from STMicroelectronics based on a glass substrate is used for the antenna manufacturing. In free space, the radiation pattern measurements show a realized gain higher than 4 dBi in the endfire direction from 56 to 65 GHz. The impact of the integration of the antenna on the PCB is investigated in details showing reasonable disturbance of the reflection coefficient, but strong modifications of the radiation pattern, especially the pointing direction of the main beam. From the analysis of the surface waves propagating along the PCB when the Vivaldi is integrated, a novel topology is proposed to preserve the main radiation in the endfire direction with enhanced realized gain.
