To prevent far-field radiation characteristics degradation while increasing bandwidth, an attempt has been made to design and fabricate a microstrip antenna. An electromagnetic band gap (EBG) structure, including a layer of a metallic ring on a layer of Rogers 4003C substrate, is used. For a better design, a patch antenna with and without the EBG substrate has been simulated. The results show that the bandwidth can be improved up to 1.6 GHz in X-band by adding the EBG substrate. Furthermore, using this structure, a dual-band antenna was obtained as well. Finally, to validate the simulation results, a comparison has been done between simulation data and experimental results which demonstrate good agreement.

使用用于 X 波段应用的单层超材料基板提高平面天线的带宽

为了在增加带宽的同时防止远场辐射特性劣化，已经尝试设计和制造微带天线。使用了电磁带隙 (EBG) 结构，包括在 Rogers 4003C 衬底层上的金属环层。为了获得更好的设计，我们对带有和不带有 EBG 基板的贴片天线进行了仿真。结果表明，通过添加EBG衬底，X波段带宽可以提高到1.6 GHz。此外，利用这种结构，还获得了双频天线。最后，为了验证仿真结果，对仿真数据和实验结果进行了比较，结果显示出良好的一致性。
