摘要
本文中我们研究了基于人工局域表面等离激元谐振器的电小尺寸多频天线,其电尺寸仅为0.11λ×0.1λ,覆盖GSM900,GSM1800,Wi Fi三个频带,具有较高增益。仿真结果和实验测量结果吻合良好。该天线具有尺寸小、增益中等、多频带工作的特点,可用于无线能量收集、物联网、无线传感网等领域。
Here a subwavelength multiband high gain receiving antennas have been proposed using corrugated ring resonator printed on a thin dielectric substrate with spiral-shaped defect ground structure(DGS). The multiband antennas have a small size of only 0.11λ*0.1λ, covering GSM900, GSM1800, Wi Fi bands. Numerical simulations and measurements agree well. Such subwavelength multiband high gain receiving antennas are necessary for efficient wireless energy harvesting(WEH), which can find more applications in various areas including internet of things(Io T), wireless sensor network(WSN), etc.
