This book presents the state-of-the-art millimetre wave antennas for next-generation 5G communications. The antenna is an integral part of a communication system, and it is regarded as an intelligent sub-system which can support beamforming, multiple-input, multiple-output (MIMO), massive MIMO and other multiplexing techniques for advanced communication systems. Since propagation losses associated with the millimetre waves (mm-waves) and the signal blockage due to the objects present between transmitter and receiver restrict the performance of the millimetre wave wireless system, novel antenna topologies are required to address such issues. In the book, various aspects of the antenna design are highlighted related to millimetre wave 5G communication including 28-GHz channel characteristics, mm-wave antenna requirements, antenna design strategies for 28 GHz, MIMO/multibeam antennas and mm-wave lens antennas.

The use of the optical spectrum for wireless communications has gained significant interest in recent years. Applications range from low-rate simplex transmission links using existing embedded CMOS cameras in smartphones, referred to as optical camera communications (OCC), mobile light fidelity (LiFi) networking in homes, offices, urban and sub-sea environments to free-space gigabit interconnects in data centers and point-to-point long-range wireless backhaul links outdoors and in space. This exciting book focuses on the use of optical wireless communications (OWC) for mobile use cases. Channel modeling techniques are provided for mobile multiuser scenarios, and will introduce key building blocks to achieve LiFi cellular networks achieving orders of magnitude improvements of area spectral efficiency compared to state-of-the-art. Challenges that arise from moving from a static point-to-point visible light link to a LiFi network that is capable of serving hundreds of mobile and fixed nodes are discussed. An overview of recent standardization activities and the commercialization challenges of this disruptive technology is also provided.
