Research has shown that more than 70% of information that humans receive is perceived by vision. Similarly, vision systems are also very important for robots and have basically become the standard configuration of robots. It is fundamental for robots to understand the environment and execute tasks, and it is also an important entrance to realize robot intelligence. With the rapid development of Deep Learning (DL) technology in recent years, task-oriented researches in vision, such as visual servoing, target recognition, tracking, and image understanding, have made remarkable progress. However, it should be noted that these visual algorithms are all developed for images with good quality and stable lighting conditions. In fact, robots often need to work in complex, dynamic, or unstructured environment. At this time, vision algorithms often lack adaptive ability and robustness to the environment.

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.
