This book presents state-of-the-art millimetre wave antennas for next generation 5G communications. The propagation losses associated with the millimetre waves and the signal blockage due to the objects present between transmitter and receiver require novel antenna topologies to address these issues. Various aspects of antenna design related to millimetre wave 5G communication including 28-GHz channel characteristics, mmWave antenna requirements, antenna design strategies for 28 GHz, MIMO/multibeam antennas, and mmWave lens antennas are highlighted. Apart from the general antenna requirements...
