本文提出了一种基于两相状态的多波束交换方案，该方案实现在定制设计的4x4天线阵列上，工作带宽为1.5GHz，约为14GHz。实验验证了天线阵列和波束切换方案。一个设计用于产生两个相位状态的相位网络被用于实验验证波束切换，并提出了五个波束状态，尽管这可以扩展到使用分裂波束作为构建多波束的构建块的其他配置。该天线可以在多用户毫米波大规模MIMO场景中找到潜在的用途，这些场景需要沿选择方向同时发送多个波束。
The paper presents a two-phase state based multi-beam-switching scheme implemented on a custom-designed 4x4 antenna array operating with a bandwidth of 1.5GHz around 14GHz. The antenna array and the beam-switching scheme have been experimentally validated. A phasing network designed to produce two phase states is used to experimentally validate the beam-switching and five beam states are presented, though this can be extended to other configurations using the split beam as a building block to construct multiple beams. The antenna can find potential use in multi-user millimetre-wave massive MIMO scenarios which require simultaneous multiple beams along selective directions.
