Abstract

Here an electrically small multiband antenna based on spoof localized surface plasmons (LSPs) has been proposed using corrugated ring resonator printed on a thin dielectric substrate with complementary metallic spiral structure (MSS) on the ground plane. It has been found that the resonant frequencies of spoof LSPs redshift by tuning the arm length of the complementary MSS, which leads to the miniaturization of the antenna. The fabricated multiband antenna has a small size of only 0.11λ × 0.1λ, covering GSM900, GSM1800, and WiFi bands. Such electrically small multiband antenna with high gain is necessary for efficient wireless energy harvesting (WEH), which can find more applications in various areas including Internet of Things (IoT), wireless sensor network (WSN), etc.

基于欺骗局域表面等离子体的电小型多波段天线
本文提出了一种基于欺骗局域表面等离子体(LSPs)的电小型多波段天线,该天线采用波纹环形谐振腔印刷在薄介质衬底上,并在地平面上具有互补金属螺旋结构(MSS)。研究发现,通过调整互补MSS的臂长,诱骗LSPs的谐振频率会发生红移,从而使天线小型化。制作的多波段天线尺寸很小,仅为0.11λ × 0.1λ,覆盖GSM900、GSM1800和WiFi频段。这种具有高增益的电小多频带天线是实现高效无线能量采集(WEH)所必需的,在物联网(IoT)、无线传感器网络(WSN)等各个领域都有更多的应用。
