基于非均匀超表面的带宽和增益改善型缝隙天线设计OA
Design of slot antenna with bandwidth and gain improved based on nonuniform metasurface
针对贴片天线普遍存在带宽及增益性能不足的问题,提出了一种通过非均匀超表面实现的带宽和增益改善型天线.首先,采用带有切角的缝隙贴片作为初始天线;然后,为进一步增强辐射特性,围绕初始天线周围排列了方形切角贴片,以此形成非均匀超表面.仿真结果表明,与初始天线相比,额外产生了两个谐振频率,导致反射系数S11 带宽范围达到4.4～6.6 GHz.此外,轴比值突破了3dB线,3 dB轴比带宽范围为4.7～5.7 GHz,增益平均提高了3 dB,峰值增益达到1…查看全部>>
In order to solve the problem of insufficient bandwidth and gain performance of patch antenna,this paper presents a kind of antenna with bandwidth and gain improved which is realized by a nonuniform meta-sur-face.Firstly,slit patches with cut corners are used as the initial antenna.Then,to further enhance the radiation properties,square corner-cut patches are arranged around the initial antenna to form a nonuniform meta-surface.The simulation results are sho…查看全部>>
