Spotlight On Massive MIMO/Beamforming
MIMO System Simulation In WinProp

This white paper presents and discusses practical examples of communication simulations involving MIMO technology. It also discusses two workflows existing for MIMO simulations and presents an example with relevant results for each.

Design And Physical Realization Of Phased-Array Antennas For MIMO And Beam-Steering Applications

This white paper explores basic phased-array theory and the design considerations behind next-generation antenna systems and examines the new capabilities recently added to electronic design automation (EDA) software such as the NI AWR Design Environment platform.

Millimeter-Wave Beamforming: Antenna Array Design Choices And Characterization

This paper discusses fundamentals of beamforming technology, including signals, antennas, and current transceiver architectures. The paper included calculation methods for radiation patterns and some simulations results, as well as showing some real-world measurement results for small linear arrays.

What’s So “Massive” About Massive MIMO?

As the list of mobile services available grows, technologies that provide these services must evolve in order to meet this demand while simultaneously improving the overall cost structure to consumers and service operators. Massive MIMO is a key element in 5G cellular networks.

How To Design Base Station (Or Microcell) Antenna Arrays For 5G Wireless Networks

This white paper describes a simulation workflow in Ansys HFSS used to design 5G base station (or microcell) arrays. It looks to tackle problems related to the antenna’s beamforming capabilities that use MIMO techniques and describes modeling techniques used for millimeter-wave antenna arrays.

Understanding The Basics Of MIMO Communication Technology

MIMO technology is ideal for communications applications where clear line of sight is harder to achieve and the abundance of RF and microwave systems can pose interference issues. This paper covers a range of basics of MIMO communications for readers of all technical levels.

How Big Is A Wavelength?

In traditional arrays an inter element spacing of less than half the wavelength (<λ><λ/2) is required to mitigate grating lobes. To understand the shift in system design this brings about, this paper looks at the physical scale of different wavelengths compared to some familiar references.
