摘要
介绍了一种低成本高效率的W波段4×4基片集成波导(SIW)缝隙阵天线。天线阵为双层结构,上层为辐射层,采用宽边纵向偏移缝隙驻波阵,可以实现高的辐射功率,下层为馈电层,采用SIW串联缝隙馈电方式,减小了传统功分网络带来的传输损耗和实现难度。对天线阵进行了优化设计,采用标准低成本PCB工艺制作了天线阵实物样品并进行测试。测试结果与仿真结果吻合较好,天线阵在94GHz时,最大增益为16.8dB,反射系数-30.1dB,-10dB带宽为92.6～96GHz,副瓣电平19.5dB,天线阵口径效率为83%。
This article introduces a low-cost and high-efficiency W-band 4×4 substrate integrated waveguide(SIW)slot array antenna.The antenna consists a two-layer structure:the top radiation layer uses wide edge longitudinal offset slots standing wave array,which could realize high radiation efficiency;the bottom feeder layer adopts substrate integrated waveguide central rotate slots for feeding,which could decrease the transmission loss and realize difficulty of traditional power divider networks.Simulation software Ansys Electronic is used for optimizing the antenna array.The antenna sample is fabricated using the standard printed circuit board process.The test results are in good agreement with the simulation results.The maximum gain of the antenna array at 94 GHz is 16.8 dB,reflection coefficient is-30.1 dB,-10 dB bandwidth is 92.6-96 GHz,sidelobe level is 19.5 dB,the aperture efficiency of antenna array is 83%.
