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。
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.
