摘要

本文提出了一种高增益、宽带宽的毫米波双频超表面天线。该天线由一个印刷脊隙波导、两个t形槽和超表面组成。超表面的所有目标模态均由两个t形槽激发。加在槽上的超表面增强了辐射性能，提高了增益。设计并仿真了该天线实例，其- 10-dB带宽分别为11.3% (26.73 ~ 29.83GHz)和11.3% (38.03 ~ 42.6 GHz)，最大增益分别为9.85 dBi和10.33 dBi。

A Millimeter-Wave Dual-Band Wideband Metasurface Antenna Based on Printed Ridge Gap Waveguide Feeding

In this paper, a millimeter-wave dual-band metasurface antenna is proposed with high gain and wide bandwidth. The proposed antenna is composed of a printed ridge gap waveguide, two T-shaped slots, and the metasurface. All target modes of the metasurface are excited by two T-shaped slots. The metasurface loaded on the slots enhances the radiation performance and improves the gain. An example of the proposed antenna is designed and simulated with the −10-dB bandwidths of 11.3% (26.73–29.83GHz) and 11.3% (38.03–42.6 GHz), and the maximum gains of 9.85 dBi and 10.33 dBi.
