摘　　要：提出了一种介质谐振器加载的基片集成波导槽阵列天线结构,并给出了简单、快速的设计方法。通过Ansoft HFSS仿真软件进一步优化,可得到性能优良的天线设计结果。利用所给设计方法具体设计了一种K波段圆柱形介质谐振器加载的四元横向槽阵列天线,仿真计算结果表明该天线具有大约450MHz的-10dB回波损耗带宽,最大增益为11.8dB,且辐射效率达92%。A novel substrate integrated waveguide slot array antenna loaded with dielectric resonators was proposed, and a simple and quick design approach for this antenna was given. With the help of Ansoft HFSS for further optimization design, good results could be obtained. Using the design approach proposed, a substrate integrated waveguide four-element transverse slot array antenna loaded with cylindrical dielectric resonators at K-band was designed. The simulation results show that the bandwidth of-10dB return loss is about 450MHz, and the maximum gain of 11.8dB and radiation efficiency of 92% are obtained.
