Wideband tapered slot antenna for applications in ground penetrating radar

摘要

Abstract >A planar slotted patch antenna is proposed for ground penetrating radar (GPR). The proposed antenna has a wide bandwidth ranging from 600?MHz to 4?GHz. Tapered slot feeding, curved ground plane, and slot loading are used for a wideband operation, whereas resistive loading is utilized for removal of notch band. Current loops made by slots are bifurcated with the use of 50?Ω resistors. The antenna is designed and optimized to achieve good performance, especially at lower frequencies while keeping the antenna's physical dimension relatively small. The time‐domain analysis of the antenna is performed, and the comparative graph is added after analysis to validate its performance in the impulse‐based radar. Furthermore, a sandbox test is conducted; the experimental results show the significance of the proposed antenna toward GPR application. </abstract> </span> <span class="z_kbtn z_kbtnclass hoverxs"

<P>建议平面开槽贴片天线，用于接地穿透雷达（GPR）。所提出的天线的宽带宽度范围为600？MHz至4？GHz。锥形槽进给，弯曲的接地平面和槽装载用于宽带操作，而电阻负载用于去除凹口带。通过使用50Ω电阻器的槽制成的电流环。天线设计并优化以实现良好的性能，尤其是在较低频率下，同时保持天线的物理维度相对较小。执行天线的时域分析，并且在分析之后添加比较图以验证其在基于脉冲的雷达中的性能。此外，进行沙箱试验; 实验结果表明，所提出的天线对GPR应用的重要性。</ p> </摘要> </span> <span class="z_kbtn z_kbtnclass hoverxs" style="display: none;">展开▼</span> </div> </div> <div class="record"> <h2 class="all_title" id="enpatent33" >
