This paper is presented a Compact Wideband Rectangular Microstrip Antenna for the S and C Bands Applications. This proposed antenna has designed by Optimized Defected Ground Structure, tempered feedline as feed technique and superstrate with reflector. These three techniques have been utilized to achieve a wideband, high gain and compactness of the antenna due to enhance the perfect impedance matching. This antenna design is designed and tested on the substrate material of the FR4 epoxy of the thickness of 1.6mm at 6 GHz. The design and results simulation of this design has been done in HFSS 14 V software and the fabricate design is tested with the combinational network analyzer in the anechoic chamber. The results of the simulated and fabricated have been observed as the impedance bandwidth is 3.56 GHz (from 2.65 to 6.21 GHz) and 4.07 GHz (from 2.3 to 6.37 GHz) respectively. The simulated and measured designs of the proposed antenna have been a good agreement between them. The main applications of this antenna are lower 5G (sub 6 GHz), WiMax, WLAN and SatCom.

本文介绍了一种适用于 S 和 C 波段应用的紧凑型宽带矩形微带天线。该天线采用优化缺陷接地结构、回火馈线作为馈电技术和带有反射器的覆盖层设计。由于增强了完美的阻抗匹配，这三种技术已被用于实现天线的宽带、高增益和紧凑性。该天线设计是在厚度为 1.6mm 的 FR4 环氧树脂基板材料上设计和测试的，频率为 6 GHz。该设计的设计和结果仿真已在 HFSS 14 V 软件中完成，并且在消声室中使用组合网络分析仪对制造设计进行了测试。观察到模拟和制造的结果是阻抗带宽为 3.56 GHz（从 2.65 到 6.21 GHz）和 4.07 GHz（从 2. 3 至 6.37 GHz）分别。所提出的天线的模拟和测量设计在它们之间具有很好的一致性。这种天线的主要应用是较低的 5G（低于 6 GHz）、WiMax、WLAN 和卫星通信。
