In order to deliver the large increase in wireless data transfer needed for the new 5G wireless standard, spectrum in the millimeter wave range will be needed. There is simply not enough available spectrum in the sub 6GHz range. The millimeter wave range is largely unregulated with wide chunks of available bandwidth making it ideal for data transfer applications.
This paper discusses absorber technologies and their uses in 5G mmWave systems. It identifies Laird absorbers for this frequency range and describes how they are tested and characterized.
