摘　　要：设计了一款高增益、低副瓣、高效率宽带双极化波导缝隙滤波天线阵。采用四脊波导实现天线宽带性能,采用十字缝结构实现天线辐射单元双极化性能,采用全并馈馈电形式减小了天线阵馈电网络复杂度。通过在天线阵中集成设计直线型频变耦合滤波器,提高了滤波天线的带外抑制性能。实物测试结果与仿真结果吻合良好,验证了设计方法的正确性。A broadband dual-polarization slot waveguide filter antenna array with high gain,low sidelobe and high efficiency was designed.The broadband performance of the antenna was realized by four-ridge waveguide.The dual-polarization radiation performance was realized by the cross-shaped aperture.The full-corporate feed design was contributed to decrease the complexity of the feed network.Furthermore,an in-line frequency-dependent coupling(FDC)filter which can be integrated into the antenna array was synthesized and designed to improve out-of-band suppression.The measured results agree well with the simulated results,which confirms the validity of the proposed approach.
