摘要

提出了一种允许极化可重构的超表面天线。质谱天线由质谱天线和源天线组成，由一个小气隙隔开。质谱由衬底上的16个相同的单位细胞组成，其中每个单位细胞是一个角截断的正方形补丁。源天线采用微带馈电槽天线(MFSA)。MS将MFSA产生的线极化(LP)信号转换成具有更宽回波损耗带宽(RLBW)的圆极化(CP)信号。通过旋转MS相对于MFSA，可以实现不同的极化。为了验证仿真结果，制作并测量了MS天线。仿真结果与实测结果吻合良好。MS天线的工作频率为2.4 GHz，适用于WLAN应用。

A 2.4 GHz Polarization Reconfigurable Metasurface Antenna

A metasurface (MS) antenna that allows polarization reconfigurability is proposed. The MS antenna is formed by a MS and source antenna, separated by a small air gap. The MS consists of 16 identical unit cells on a substrate, where each unit cell used is a corner truncated square patch. A microstrip fed slot antenna (MFSA) is used as the source antenna. The MS converts the linearly polarized (LP) signal generated by the MFSA into a circularly polarized (CP) signal with wider return loss bandwidth(RLBW). By rotating the MS relative to the MFSA, different polarizations could be achieved. For verification of simulation results, the MS antennas are fabricated and measured. Simulated and measured results show good agreements. The MS antenna has an operating frequency of 2.4 GHz, suitable for WLAN applications.
