介绍了一种用于工业储罐中25ghz工业雷达测量的介质透镜天线。由于直径的限制，孔径效率是这些应用的重要基准。该方法采用了一个巨大的聚四氟乙烯透镜体，在直径为74 mm时，测量孔径效率为104%。这相当于25.9 dBi的增益。主瓣的3db角宽度为8.4°/ 8.6°，副瓣电平为−17.0 dB /−17.6 dB。
A dielectric lens antenna for 25 GHz industrial radar measurements in industrial tanks is presented. Due to the limited diameter, the aperture efficiency is an important benchmark for these applications. The presented approach uses a massive PTFE lens body, which results in a measured aperture efficiency of 104% at a diameter of 74 mm. This corresponds to a gain of 25.9 dBi. The main lobe has a tight 3 dB angular width of 8.4°/ 8.6° with a side lobe level of −17.0 dB /−17.6 dB.
