摘　　要：研究了一种基于非对称单脊波导的宽边缝隙天线.在Taylor综合法的基础上计算了非对称单脊波导缝隙天线的缝隙辐射参数,设计了一个11元副瓣电平为-25dB的非对称单脊波导缝隙天线,利用HFSS软件对其进行建模仿真,并对缝隙天线的参数特性作了分析和优化.结果表明,所设计的非对称波导缝隙天线不仅尺寸较小,而且具有良好的带宽和低副瓣特性.The slot antenna based on asymmetrical single-ridged waveguide was researched.Based on the Taylor synthesis method,which could calculate the radiation parameters of the aperture array antenna in the asymmetric single ridge waveguide slot array,an asymmetric single ridge waveguide slot antenna with 11 elements and the side lobe level of-25 dB is designed.The parameters of the slot antenna are analyzed and optimized by the simulation of HFSS software.The results show that the asymmetric waveguide slot antenna is not only small,but also has a good bandwidth and low side lobe characteristics.The work can provide a clue for the design and application of this kind of antenna.
