摘要

提出了一种具有机械调谐的频率可重构天线，可在2.51 ~ 3.70 GHz范围内进行频率调谐。该设计包括一个缝隙天线和一个具有等腰三角形环单元单元的新型超表面。通过旋转该天线，该天线在频率重构中获得了良好的性能。该天线结构紧凑，直径为50mm，高度为3mm，在整个调谐范围内的辐射效率高达90%。实测和仿真结果验证了可重构天线的宽频可调性，证明了该天线适用于先进的多标准无线通信应用。

Mechanically reconfigurable antenna based on novel metasurface for frequency tuning-range improvement

A frequency-reconfigurable antenna with mechanical tuning, providing the frequency tuning from 2.51 to 3.70 GHz, is presented. The design comprises a slot antenna and a novel metasurface (MS) with isosceles triangular-loop unit cells. Through pivoting of the novel MS, this antenna achieved good performance in the frequency reconfiguration. Moreover, the reconfigurable antenna have the advantages of compact structure with a diameter of 50mm and a height of 3mm, and good radiation efficiency of up to 90% across the tuning-range. Measured and simulated results testify the wide frequency tunablity of the reconfigurable antenna, and demonstrate it is suitable for advanced multi-standard wireless communication applications.
