摘要

摘要提出了一种采用衬底集成波导(SIW)技术，采用紧凑的两层6 × 6波束形成网络(BFN)和6 × 2缝隙天线实现的低轮廓六波束天线。所提出的6 × 6 BFN的主要组件是3 × 3多孔径耦合器、层间混合耦合器和嵌入在两个微波衬底上的几个移相器。该天线的设计、仿真和制作工作范围为28 - 32ghz。该天线的尺寸为82 × 31.8 × 0.787 mm 3，与同类产品相比，由于其尺寸紧凑，因此可以成为5G应用的合适选择。样机测试表明，该结构具有稳定的波束形成性能，仿真结果与实测结果吻合良好。天线产生±9°、±30°和±54°方向的6束辐射，具有良好的回波损耗和隔离性。

A low-profile SIW multi-beam antenna array fed by a compact two-layer 6 × 6 BFN

Abstract This paper presents a low-profile six-beam antenna implemented by a compact two-layer 6 × 6 beamforming network (BFN) and a 6 × 2 slot antenna in substrate integrated waveguide (SIW) technology. The main components of the proposed 6 × 6 BFN are 3 × 3 multi-aperture couplers, interlayer hybrid couplers, and several phase shifters which are embedded on two microwave substrates. The proposed antenna has been designed, simulated, and fabricated for the frequency range of 28–32 GHz. The size of this antenna is 82 × 31.8 × 0.787 mm 3 , which can be a suitable choice for 5G applications due to its compact dimensions compared to similar works. Prototype testing shows that the proposed structure presents a stable beamforming performance both in simulation and measurement with good agreement. The antenna generates six radiation beams in directions ±9°, ±30°, and ±54° with good return losses and isolations.
