This article goes through the most popular electromagnetic solvers for periodic structures, describing their optimal use cases, advantages and disadvantages. As a practical example, a 4x4 mmWave cavity antenna array is simulated using a Time Domain Solver, Direct Frequency Domain Solver and Domain Decomposition Solver. The goal is to compare the available 3D solvers and find the most optimal settings for simulations of periodic structures.

Researchers require a flexible and scalable test bed to gain insight into the performance of their evolving 6G designs. Keysight has developed a test bed for the D- (110 to 170 GHz) and G-Bands (140 to 220 GHz) to measure error vector magnitude (EVM). 

This application note demonstrates use of HYPERLABS’ broadband coaxial components as general-purpose analog signal processing components for the generation of novel time-domain waveforms.

With 3GPP finally recognizing these benefits and including it in the Release 18 standard, it is now nearly certain that the access network is going Full Duplex making Self-Interference Cancellation technology a critical piece of the puzzle. Read about the progress being made.

GRIN dielectric lenses/antennas have been a hot topic of research for virtually every microwave/mmWave application, from military/defense, aerospace/space, to commercial telecommunications. There have even been several companies, products, and government/DoD grants using GRIN dielectric lens/antenna technology. This article provides some discussion around recent research (since 2018) on GRIN dielectric lenses/antennas, and an overview of GRIN dielectric lenses/antennas being deployed or intended for practical use.
