天线阵就是按某种几何规则排列形成的一组天线，其中的单个天线称为“阵元”。 排成直线的一组天线称为线阵，最常见的是均匀线阵。“均匀”是指各阵元之间的距离相等，天线“均匀排列”。当然，也有非均匀线阵。 线阵的方向图是一维的，一般应用于 ...

All 5G systems networks are going to use MIMO (massive input, massive output) antenna arrays and beamforming. Many 5G systems will operate in millimeter wave (mmWave) spectrum. Designing MIMO arrays ...

Dublin, March 21, 2025 (GLOBE NEWSWIRE) -- The "Macro Passive/Massive MIMO Antenna Array Antenna Vendor Market Share Analysis, 2022-2023" report from EJL Wireless Research has been added to ...

Extensive efforts have been made in designing large multiple-input multiple-output (MIMO) arrays. However, there is still a gap between array antenna design and MIMO performance evaluation in ...

A radar can be used to locate a buried object. Therefor the radar should operate at low frequencies to be able to penetrate the medium the object is buried in and it should have a high spatial ...

2019 will see the world’s first 5G commercial deployments in some markets. Whether 5G networks can be constructed economically is a focus of global operators. One of the common expectations of 5G is ...

Beamforming, based on multiple-input, multiple-output (MIMO) phased-array antennas, looks to make up a component part of the overall 5G cellular technology. While phased-arrays have been the basis of ...
