摘要:
研究一种基于超表面的60 GHz 1×2宽带天线阵列.为降低传输损耗,天线阵列由间隙波导功分器馈电,间隙波导传输线两侧放置电磁带隙结构,能量通过缝隙与顶层超表面耦合,从而向空间辐射.天线阵列安装在Rogers 4350b介质基板上,由超表面辐射器引入的准TM30谐振模式与缝隙辐射单元的本征模式结合,从而拓展天线带宽,改善天线增益.研究结果表明:天线阵列-10 dB |S11| 带宽仿真结果为49.3~65.0 GHz,实测结果为48.5~64.8 GHz,覆盖57.0~64.0 GHz范围的无授权毫米波通信频段;在匹配带宽内,天线的最大增益为11.8 dB,3 dB增益带宽为15%.
Abstract:
A 60 GHz 1×2 gap waveguide coupled feed broadband antenna array based on hypersurface is studied. In order to reduce the transmission loss, the antenna array is fed by an optimized gap waveguide power divider. The electromagnetic band gap structure is placed on both sides of the gap waveguide transmission line, and the energy is coupled with the super surface of the top layer through the gap, so as to radiate into space. The antenna array is mounted on the Rogers 4350b dielectric substrate. The quasi TM30 resonant mode introduced by the hypersurface radiator is combined with the eigenmode of the slot radiating element to improve the bandwidth and gain of the antenna. The research results show that the antenna array -10dB |S11| bandwidth, the simulation results are 49.3 to 65.0 GHz, the measured one ranges from 48.5 to 64.8 GHz, covering 57.0 to 64.0 GHz unauthorized millimeterwave communication band; in the matching bandwidth, the maximum gain of the antenna is 11.8db, and the 3dB gain bandwidth is 15%.
