The aim of this article is to introduce a compact configuration of an arc shape ultra-wideband (UWB) planar antenna with nominal characteristics towards surface penetrating radar (SPR). The design is implemented to enhance antenna gain and bandwidth widening, that makes it a suitable device to be used in the detection or scanning operations. To serve the purpose, a simplified defected ground structure (DGS) method is been adopted, in which different rectangular size slots were induced over the surface of the ground plane to condense the surface current distribution of the radiating patch. Furthermore, the measurements elaborated that the proposed DGS based antenna has a very wide bandwidth from 3 to 16 GHz, which is significantly greater than the defined UWB range. The resultant gain is 6.2 dB that helps in deep penetration and the wider bandwidth can carry more information, which makes the antenna a potential device to be used in detection applications. The detection capacity of antenna has been validated using monostatic and bistatic based experimental configurations. Apart from this, a simple structure and low cost fabrication of antenna makes it appropriate for SPR applications.

本文的目的是向表面穿透雷达（SPR）引入具有标称特性的弧形超宽带（UWB）平面天线的紧凑配置。实施该设计以增强天线增益和带宽加宽，使其成为用于检测或扫描操作的合适设备。为了达到这个目的，采用了一种简化的缺陷接地结构（DGS）方法，在该方法中，在接地平面的表面上引入了不同的矩形尺寸的缝隙，以凝聚辐射贴片的表面电流分布。此外，测量结果详细说明了所提出的基于DGS的天线具有3至16 GHz的非常宽的带宽，该带宽明显大于定义的UWB范围。所得增益为6。2 dB有助于深度穿透，更宽的带宽可以承载更多信息，这使得该天线成为检测应用中潜在的设备。天线的检测能力已使用基于单静态和双静态的实验配置进行了验证。除此之外，天线的简单结构和低成本制造使其适用于SPR应用。
