摘要
提出并分析了两类基于基片集成波导(Substrate Integrated Waveguide,SIW)的缝隙稀疏阵列天线.减少缝隙单元的数目,对于(基片集成)波导缝隙阵列天线具有重要的意义,可以简化设计、展宽带宽、降低加工工艺要求等.阵列天线稀疏化明显降低了缝隙单元间的互耦,使得低副瓣天线的设计更容易.全波仿真结果有效验证了设计的正确性和有效性.
Two types of longitudinal slot antenna sparse arrays based on substrate integrated waveguide （SIW） technology are proposed and investigated. This design method could lead to an enhanced bandwidth and a lower requirement for fabrication accuracy, while preserving acceptable radiation properties. Moreover, it is easy to realize low sidelobe levels （SLID performance due to the lower internal and external mutual couplings. The full wave simulation results show that the sparse designs are effective and feasible.
