摘　　要：给出了波导窄边缝隙天线频带特性的分析方法。对于行波天线,基于缝隙电导在频带内的变化改变了口径分布,进而影响天线波瓣性能。该文对不同缝隙分布的天线带内性能计算,探讨了主要设计参数的选择。制作了一个试验天线,测试结果与理论分析一致。In this paper, the frequency bandwidth characteristics analysis method of the narrow wall slotted-waveguide array is presented. In nonresonant waveguide-fed slot-antenna arrays, the slots conductance is variational in frequency bandwidth, and it will change the aperture distributions and affect the beam performances. By calculating the beam performances corresponding different slots distributions, the selections of the main design parameters are discussed. An experiment antenna is made and results are consistent with the theoretical analysis.
