Spatial statistics is a powerful tool for analyzing data that are illustrated as points or positions in regular non-regular state space. Techniques proposed to investigate the spatial association between neighboring based on point process analysis. One of main goals simulate real (such antenna base stations) using type most closely matches data. patterns could be detailed describing observed an...

Modern wireless networks such as 5G require multiband MIMO-supported Base Station Antennas. As a result, antennas have multiple ports to support range of frequency bands leading arrays within one compact antenna enclosure. The close proximity the results in significant scattering degrading pattern performance each band while coupling between leads degradation return loss and port-to-port isolat...

Mobile network operators demand small base station antennas and high physical layer throughputs. In the downlink, high physical layer throughputs can be achieved by exploiting transmit diversity. Given that the correlation between different propagation paths reduces the achievable throughput, it is commonly conjectured that the greater the transmit antenna spacing, the better the radio link per...

We present a new compact wideband MIMO (multiple input multiple output) antenna – the double-sided 4-port armtapered self-grounded monopole array, briefly referred to as the butterfly antenna, in the paper. The antenna is very compact with low correlation between ports and high diversity gain. The genetic algorithm optimization scheme has been employed in the design. Simulation results have bee...

Plane-wave generators (PWGs) for over-the-air testing of 5G base stations offer the advantages efficiency and economy. Many new bands, such as n28, are progressively being introduced, driving bandwidth improvement PWGs. The cost amplitude–phase control networks is also increased by broadband range required testing. In view above challenges, in this paper, a low-frequency ultra-wideband PWG repo...

<span>Massive internet of things (IoT) in 5G has many advantages as a future technology. It brings some challenges such lot devices need massive connection. In this case, multiple-input multiple-output (MIMO) systems offer high performance and capacity communications. There is challenge correlation between antennas MIMO. This paper proposes three-sectors MIMO base station antenna for 5G-N...
