摘要

本文设计了一款基于超表面结构的低剖面、宽带型、双端射表面波天线。该天线是由沿x方向一维调制等效折射率的超表面构成。超表面的基本单元结构采用亚波长方贴片。由仿真结果可知,该天线在2.4GHz增益达6.486 d Bi,-10 d B阻抗带宽达66.32%,并且在整个工作频带范围内方向性和增益都保持良好。
In this paper, a low-profile, broadband and bidirectional end-fire surface-wave antenna based on the modulated one-dimensional meta-surface is designed. The antenna consists of the one-dimension meta-surface with the effective refractive index, which is modulated along the x-axis. The basic unit structure of the meta-surface is constructed using the sub-wavelength patch. As illustrated by the simulated results, with the aid of the meta-surface, the peak gain values in two end-fire directions could achieve 6.486 d Bi at 2.4GHz. Accordingly, its-10 d B fractional impedance bandwidth is as high as 66.32 %. In addition, the directivity, as well as the gain, of the proposed antenna maintains stable over the entire operational frequency band.
