摘要

本文提出了一种用于探地雷达的圆极化矩形贴片超宽带(UWB)天线。设计的几何结构由准矩形辐射体和局部地平面构成。它印刷在低成本的FR-4基板上，具有25 - 30 - 1.5毫米的紧凑尺寸。计算得到的CP准矩形贴片天线的阻抗带宽(IBW)范围为3.16 GHz ~ 13.7 GHz(125.03%)。此外，该样机的测量IBW范围从3.2 GHz到大于14 GHz(>125.58%)，覆盖了整个UWB范围。此外，所设计的天线具有较宽的轴比带宽(ARBW)，从4.23 GHz扩展到7.02 GHz(49.6%)。因此，可以在整个工作带宽内模拟出具有良好峰值增益和高辐射效率的稳定辐射模式。

Circularly polarized quasi-rectangular patch UWB antenna for GPR applications

In this paper, a Circularly Polarized (CP) rectangular patch Ultra-Wideband (UWB) antenna is presented for Ground Penetrating Radar (GPR) applications. The designed geometry is constructed of a quasi-rectangular radiator and a partial ground plane. It is printed on the low-cost FR-4 substrate that has a compact size of 25?30?1.5 mm3. The calculated Impedance Bandwidth (IBW) of the proposed CP quasi-rectangular patch antenna is spanning from 3.16 GHz to 13.7 GHz (125.03%). Moreover, the measured IBW of the fabricated prototype is spanning from 3.2 GHz to greater than 14 GHz (>125.58%) which covers the entire UWB range. Besides, the designed antenna reveals a wide Axial Ratio Band-Width (ARBW) extending from 4.23 GHz to 7.02 GHz (49.6%). Therefore, stable radiation patterns with an agreeable peak gain and high radiation efficiency are simulated over the whole working bandwidth.
