Abstract

Tank level measurement is an important research area in radar technology. Level measurement using radar technology is a safe solution even under extreme process conditions, such as high pressure, temperature, and vapors. Special antennas are required to meet electromagnetic requirements such as high gain, low sidelobe level, and high bandwidth. Another requirement is a small size and good manufacturability of the antenna. One promising solution is the use of microstrip antennas for tank-level measurements. This paper presents a special microstrip antenna, that meets the main requirements in addition to a circular antenna layout, which fills optimally the tank hatch. To do this, we created a special antenna layout with a suitable feeding network and added an optimized ring around the antenna system, which significantly reduces the sidelobe level. The center frequency of the antenna is 25 GHz with a 1 GHz bandwidth.

摘要

油箱液位测量是雷达技术中的一个重要研究领域。即使在极端的工艺条件下，如高压、高温和蒸汽，使用雷达技术进行液位测量也是一种安全的解决方案。特殊的天线需要满足高增益、低旁瓣电平、高带宽等电磁要求。另一个要求是天线尺寸小、制造工艺好。一种有前途的解决方案是使用微带天线进行油箱液位测量。本文提出了一种特殊的微带天线，除了圆形天线布局外，它还满足主要要求，该布局可以最佳地填充油箱舱口。为此，我们创建了一个具有合适馈电网络的特殊天线布局，并在天线系统周围添加了一个优化的环，这显著降低了旁瓣电平。天线的中心频率为 25GHz，带宽为 1GHz。
