宽带单脊波导缝隙天线的设计

内容简介：根据传输线方程推导了单脊波导辐射缝隙有源导纳的计算公式,结合三维电磁仿真软件HFSS提取了天线阵列中辐射缝隙的有源电导,设计了一个8元单脊波导缝隙线阵,实测结果表明,副瓣为-23.61dB,VSWR≤2时的相对带宽为8%,约为矩形波导缝隙天线的2倍。

Abstract：From the transmission line equations single ridge waveguide slot active admittance formula is derived.With three-dimensional electromagnetic simulation software HFSS,the active radiation conductance of the gap in the antenna are obtained.An 8-element single ridge waveguide slot array is designed.Experimental results show that the side lobe is-23.61dB,relative bandwidth for VSWR less than 2 is about 8%,which is about 2 times of that in rectangular waveguide slot antenna.
