摘要

提出了一种利用地平面上的周期性超表面来提高多波段微带天线增益和指向性的方法。推导了封闭形式关系，并通过三维电磁仿真进行了验证。利用SRRs在地平面上改变周期性超表面结构，研究了天线的性能。结果表明，该方法提高了多波段天线结构的增益和指向性。还观察到，周期性超表面结构可以作为旋钮来调节天线在感兴趣频率上的带宽。

Gain and Directivity Enhancement for Multiband Metasurface Antennas for 5G Applications

A method to enhance gain and directivity of multiband microstrip antenna is proposed using periodic metasurface on the ground plane. The closed form relations are derived and verified via 3D electromagnetic simulation. The antenna performance has been studied by changing periodic metasurface structure using SRRs on the ground plane. It has been shown that the proposed method enhances the gain and directivity of the multiband antenna structure. It is also observed that the periodic metasurface structure can be used as a knob to adjust the bandwidth of the antenna at the frequency of interest.
