Abstract

We present a linear Vivaldi-antenna array with a misalignment-robust nongalvanic transition and scan-range-improving parasitic resonators for 5G FR2-1 base-station applications. The array covers most of the Ka-band (26.5–40 GHz) on a scan range of

$\pm 60 {\mathrm {^{\circ}}}$

with a total active reflection coefficient of below −10 dB and a scan gain of above 10 dBi. Furthermore, the parasitic resonators increase the scan range to

$\pm 85 {\mathrm {^{\circ}}}$

between 30 and 35 GHz. A prototype of the array is measured and the performance is confirmed to coincide well with the simulations.

提高扫描距离的ka波段寄生谐振腔孔耦合vivaldi天线阵列设计

我们提出了一种线性vivaldi天线阵列，该阵列具有失调鲁棒的非电跃迁和提高扫描范围的寄生谐振器，适用于5G FR2-1基站应用。该阵列在$\pm 60 {\ mathm {^{\circ}} $的扫描范围内覆盖了大部分ka波段（26.5 - 40ghz），总主动反射系数小于−10 dB，扫描增益大于10 dBi。此外，寄生谐振器在30至35 GHz之间将扫描范围增加到$\pm 85 {\ mathm {^{\circ}} $。实验结果表明，该阵列的性能与仿真结果吻合较好。
