摘要

本文介绍了一种具有稳定增益的宽带超表面天线。提出了一种加载非均匀六边形槽的4 × 4方形补片超曲面。为了在宽带范围内实现稳定的辐射性能，选择两种电流方向相同的特征模式作为超表面的工作模式。采用缝隙天线对超表面进行激励。通过将超表面天线和缝隙天线的谐振模式相结合，获得了宽带。测量结果表明，该天线−10 dB阻抗带宽为4.36 ~ 8.21 GHz (61.2%)， 2 dB增益带宽为4.36 ~ 7.2 GHz(49.1%)，峰值增益值达到10.6 dBi。

A broadband stable gain antenna using nonuniform hexagonal-Slot metasurface

ABSTRACT This paper demonstrates a broadband metasurface antenna with stable gain. A 4 × 4 square patches metasurface loaded with nonuniform hexagonal slots is proposed. To achieve stable radiation performance in broadband range, two characteristic modes with the same current direction are selected as operating modes of the metasurface. A slot antenna is employed to excite the metasurface. By combining the resonant modes of metasurface and slot antenna, the broadband is obtained. The measured results show that, the −10 dB impedance bandwidth of the proposed antenna is 4.36–8.21 GHz (61.2%), the 2 dB gain bandwidth is 4.36–7.2 GHz (49.1%), and the peak gain value reaches 10.6 dBi.

期刊介绍： Publishing eight times per year, Electromagnetics offers refereed papers that span the entire broad field of electromagnetics and serves as an exceptional reference source of permanent archival value. Included in this wide ranging scope of materials are developments in electromagnetic theory, high frequency techniques, antennas and randomes, arrays, numerical techniques, scattering and diffraction, materials, and printed circuits. The journal also serves as a forum for deliberations on innovations in the field. Additionally, special issues give more in-depth coverage to topics of immediate importance. All submitted manuscripts are subject to initial appraisal by the Editor, and, if found suitable for further consideration, to peer review by independent, anonymous expert referees. Submissions can be made via email or postal mail.
