| 摘 要： | 针对传统的水平极化波导缝隙对全向天线带宽较窄、成本较高的缺点,该文提出了一种基于基片集成波导(S IW)工艺的全向辐射的波导缝隙天线。该天线由2个背靠背安装的S IW缝隙天线阵组成,并且由隐藏在两波导之间的带状线通过探针馈电。可以实现复杂的并行馈电网络,在不影响天线全向性的同时扩展阵列带宽。给出了天线的图片和结构图。该天线水平面方向图起伏小于2.5 dB,而端口反射系数小于-10 dB的带宽达到12.5%。这种多层方案可以用于同时对增益和带宽有较高要求的场合。

| Abstract: | Traditional horizontal polarization waveguide double-slot omni-directional antenna arrays have various disadvantages,such as narrow bandwidth and high cost.This paper presents an omni-directional waveguide slot antenna based on substrate integrated waveguide technology that has two back-to-back mounted radiating waveguides fed by a stripline hidden between them.This improvement enables implementation of complex parallel feeding networks and can achieve wide bandwidths while keeping omni-directional radiatio... |
