摘要

提出了一种基于基片集成波导(SIW)技术、360°角覆盖的60 GHz开关波束喇叭阵列链路模型。每个阵列有八个相同的打印喇叭元素。这些元件相对于另一个定向45°，并且可以单独激发以在水平面上产生8个端火光束。在视距(LoS)和非视距(NLoS)方向上测量和模拟两个阵列之间的空中传输系数。通过对模拟远场的后处理优化，确定了激元的相位中心(PCs)，并将其纳入Friis方程，以准确地模拟传输。

360° Switched Beam SIW Horn Arrays at 60 GHz, Phase Centers, and Friis Equation

The link model of switched beam horn arrays at 60 GHz based on the substrate integrated waveguide (SIW) technology with 360° angular coverage is presented. Each array has eight identical printed horn elements. The elements are oriented 45° relative to one another and can be individually excited to produce eight endfire beams in the horizontal plane. The over-the-air (OTA) transmission coefficients are measured and simulated between two arrays, in the line-of-sight (LoS) and non-LoS (NLoS) directions. The phase centers (PCs) of the excited elements are determined from post-processing optimization of simulated far-fields and incorporated in the Friis equation to accurately model the transmission.
