为了应对大规模无线通信的三个重大挑战，包括传播损失，长距离传输和通道褪色，我们旨在建立带有紧凑型尺寸的Bowtie元素的混合天线阵列，用于光束形成应用。在这项工作中，我们严格地证明，与其他可用天线阵列相比，Bowtie元素可以显着改善混合天线阵列的光束性能，而且还可以显着改善其几何元素的偶极元素。我们的SINR值提高了15 dB，天线效率提高了20％，DOA估计的显着提高，与Bowtie元素的混合天线阵列的指导性相比有20％，与其几何元素相比，通过其几何元素进行了三类分类ls-S-SVM（最小二）Supports Supplate vector vector vector vector vector vector vector vector vector vector vector vection veation vection veation。提出的杂化天线阵列显示了3D均匀的方向性，并伴随着其在3D均匀的梁扫描能力中的出色性能。在40.83 dBi的情况下，缔立保持恒定，角度θ的变化和41.21 dbi，其角度变化。带有Bowtie元素的混合天线阵列的无与伦比的功能和性能使其成为大规模无线通信中光束应用应用的潜在候选者。
To address three significant challenges of massive wireless communications including propagation loss, long-distance transmission, and channel fading, we aim at establishing the hybrid antenna array with bowtie elements in a compact size for beamforming applications. In this work we rigorously demonstrate that bowtie elements allow for a significant improvement in the beamforming performance of the hybrid antenna array compared to not only other available antenna arrays, but also its geometrical counterpart with dipole elements. We have achieved a greater than 15 dB increase in SINR values, a greater than 20% improvement in the antenna efficiency, a significant enhancement in the DoA estimation, and 20 increments in the directivity for the hybrid antenna array with bowtie elements, compared to its geometrical counterpart, by performing a three-class classification LS-SVM (LeastSquares Support Vector Machine) optimization method. The proposed hybrid antenna array has shown a 3D uniform directivity, which is accompanied by its superior performance in the 3D uniform beam-scanning capability. The directivities remain almost constant at 40.83 dBi with the variation of angle θ, and 41.21 dBi with the variation of angle ϕ. The unrivaled functionality and performance of the hybrid antenna array with bowtie elements makes it a potential candidate for beamforming applications in massive wireless communications.
