摘　　要：基于基片集成波导技术与标准印刷电路板工艺,设计并实现了缝隙阵列全向天线。为展宽带宽,天线由两个相同子阵组成。采用带状线T型功分器和共面波导转接,实现天线的平衡馈电结构。测试结果与全波仿真结果表明,对称平衡馈电基片集成波导缝隙阵列全向天线具有良好的全向性,较高的增益,相对较宽的带宽和紧凑的结构。Based on the substrate integrated waveguide （SIW） technology and the standard PCB process, an SIW slot array omni-directional antenna is designed, fabricated and measured. The antenna consists of two same sub-arrays to achieve wide bandwidth. The balanced feeding structure is realized using a stripline T-junction power divider and a coplanar waveguide transition. The measured data, which are in agreement with the full-wave simulation results, show that the symmetrically balanced feeding SIW slot array omni-directional antenna features good omni-directivity, high gain, relatively wide bandwidth and also compact structure.
