【摘要】 提出了一种用于低副瓣雷达的印刷振子阵列天线的多级微带线/带状线混合馈电网络结构,具有集成度高、结构紧凑、重量轻等优点。并基于对各子网络散射矩阵的级联分析,获得了S波段中相对带宽为10%的1∶48多级混合网络的良好的散射矩阵特性。测试结果表明了本文方法的有效性。更多还原

【Abstract】 A new multi-stage microstrip and strip hybrid feeding network of printed dipole array antenna for low side-lobe radar is given,which is easy to be integrated with the radiation dipoles,and also compact and light.Moreover,on the basis of the cascaded analysis of the scattering matrix of the sub-networks,the good performances of 1∶48 hybrid network with the relative bandwidth 10% in S-band are obtained.The measured results are given and found to be valid.更多还原
