摘要
RCS在发现或识别数据以指定目标方面具有重要作用。每个目标都有一个独特的签名，用于识别将要测试的结构类型。单基地雷达使用单天线，因为它减少了特定极化信号的散射。此外，它在同一位置接收和发送。有许多应用利用方形贴片天线(SPA)，如微波系统，空间应用和....等。本文利用2014版CST软件对2.4 GHz频率下的SAP进行了设计和仿真，并将其作为确定RCS面积的目标。此外，对所设计的天线进行了多种衬底材料(FR4、RT- Roger 5880、Taconic、Baklite和DuPont-951)的建模和仿真。模拟了单站雷达在3-13 GHz和(0、60和90)度入射角下的雷达截面。仿真结果表明，在入射角θ =0°时，衬底介质材料为杜邦-951的天线的最佳RCS为-26 m2左右。
Influence Different Dielectric Materials For Square Patch Antenna on RCS
RCS has an important role in discovered or identified data for target designation. Each target has a unique signature utilizing to recognize the structure kind that will test. The monostatic radar uses a single antenna because it reduces the scattering of signals for a specific polarization. Moreover, it receives and transmits in the same location. There are many applications utilizing the Square patch antenna (SPA) such as microwave systems, space applications and .... etc. This paper is designing and simulating the SAP in 2.4 GHz frequency also it is used as a target to determine RCS area by utilizing CST software version 2014. Furthermore, the designed antenna is modeled and simulated for various kinds of substrate material (FR4, RT- Roger 5880, Taconic, Baklite, and DuPont-951). The radar cross-section of monostatic radar is simulated at 3-13 GHz and the incident angles utilized from (0,60, and 90) degrees. Finally, the simulation result appears that the best RCS of the designed antenna with the substrate dielectric material (Dupont -951) is around -26 m2 at the incident angle θ =0°.
