摘要

本文设计了一种改进的紧凑型超宽带定向领结天线，用于水下探地雷达测量。该天线采用新月形双层贴片结构和带凹槽的圆柱形反射腔，尺寸为89毫米× 89毫米× 50毫米。此外，提出了一种新的电磁波吸收介质，并在反射腔内填充，提高了天线的时域性能。组装好的天线在人工湖中进行了测量。测量结果表明，该天线具有157 ~ 600 MHz的宽工作频带，主瓣方向增益为2.76 ~ 7.77 dBi。此外，还进行了野外雷达试验。雷达图像显示出清晰的目标响应，表明该天线可以很好地用于水下探测。

A Modified Compact UWB Directional Bow-Tie Antenna for Underwater GPR

In this letter, a modified compact ultrawideband directional bow-tie antenna is designed and used for underwater ground-penetrating radar measurement. The antenna features a compact size of 89 mm × 89 mm × 50 mm, achieved through the use of a crescent-shaped, double-layer patch structure and a cylindrical reflective cavity with grooves. In addition, a novel electromagnetic wave-absorbed medium is presented and filled within the reflective cavity, improving the time-domain performance of the antenna. The assembled antenna was measured in an artificial lake. The measurement results show that the proposed antenna has a wide operating band of 157 MHz to 600 MHz, and a gain of 2.76 dBi to 7.77 dBi in the main-lobe direction. Furthermore, a field radar experiment is also conducted in the lake. The radar image shows a clear target response, indicating that the antenna can be used well for underwater detection.

期刊介绍： IEEE Antennas and Wireless Propagation Letters (AWP Letters) is devoted to the rapid electronic publication of short manuscripts in the technical areas of Antennas and Wireless Propagation. These are areas of competence for the IEEE Antennas and Propagation Society (AP-S). AWPL aims to be one of the "fastest" journals among IEEE publications. This means that for papers that are eventually accepted, it is intended that an author may expect his or her paper to appear in IEEE Xplore, on average, around two months after submission.
