提出了一种新型45度线极化基板集成波导中馈串联矩形介质谐振器天线阵列的建模、设计和优化。应用隐式空间映射技术来优化天线阵列。建立了可调电路模型作为粗略/代理模式，并使用全波求解器作为精细模型。使用八元件阵列展示了高设计和优化效率。仅通过两次迭代就优化了阵列天线的反射系数。在毫米波频段 (34-36 GHz) 运行的八元件天线阵列的实验数据用于验证设计和建模技术的性能。测量的辐射方向图表明，在 2.2 GHz 的工作阻抗带宽上，宽边波束的最大辐射增益为 13.55 dB。
The modeling, design, and optimization of a new substrate integrated waveguide middle-fed series rectangular dielectric resonator antenna array with 45 degrees linear polarization are presented. The implicit space mapping technique is applied for the optimization of the antenna array. A tunable circuit model is built, which serves as the coarse/surrogate mode, and a full-wave solver is used as the fine model. High design and optimization efficiency is demonstrated using an eight-element array. The reflection coefficient of the array antenna is optimized with only two iterations. The experimental data for the eight elements antenna array, operating at the millimeter-wave band (34-36 GHz), are used for the validation of both performance of the design and modeling techniques. The measured radiation pattern demonstrates a broadside beam with a maximum radiated gain of 13.55 dB over an operating impedance bandwidth of 2.2 GHz.
