Скачать или смотреть Millimetre waves finally fulfilling their promise - key technologies and applications

Prof Ian Robertson of the University of Leeds speaking at the 2nd Interlligent RF and Microwave Seminar, 14 October 2015 in Cambridge, UK.

The millimetre-wave frequency range is especially important for communications and sensing and will feature strongly in future generations of mobile communications standards. They are finding new applications in machine-to-machine (m2m), wearables, BANs and the Internet of Things (IoT). After the long-since forgotten GaAs vs. silicon debate in the 1990s, silicon has emerged stronger than ever, challenging the III-Vs even in the millimetre-wave range. SiP/SoS technology increasingly underpins the global electronics industry and provides a multi-technology platform by which integrated circuits, devices and components from any technology (Si/SiGe, GaAs, GaN, InP, graphene, ferroelectrics, microfluidic, bionanoelectronic, etc.) can be integrated to form a system. There remain significant challenges to address: On the one hand, there is an urgent need to push down the cost of millimetre-wave systems - for example, as this frequency range is exploited for 5G+ systems, where sophisticated steerable antenna arrays are required. On the other, there is a significant technical challenge to be overcome in order to push the performance envelope so that SiP solutions can be employed for systems beyond 100 GHz, including terahertz systems - as and when the necessary devices become commercially available. SiP/SoS technology will finally deliver the explosion in applications of the millimetre-wave and terahertz bands for applications such as 5G+, IoT, m2m communications, biosensing, imaging, security screening, etc.
