摘　　要：采用矩量法分析了缝隙宽度对窄边压缩型波导缝隙天线的导纳随频率变化的影响,得出了窄缝带宽特性优于宽缝的结论。结合波导缝隙天线的设计方法分析了有源导纳的带宽特性,并给出了一种宽缝、窄缝混合排列的新型宽带结构,仿真结果证明了该方法的准确性和有效性。The method of moments is used to analyze, the influence of gap width on the admittance of narrow compression waveguide slot antenna changing with the frequency, and concluded that the Narrow Gap wide bandwidth characteristics superior to the conclusions. Bird slot antenna with the design of active admittance of the bandwidth, and gives a wide slit, Narrow mixed with the new broadband structure, the simulation results proved the accuracy and effectiveness.
