7. Advanced Antenna Systems for 5G Mobile Communication

High-speed wireless communication has become an integral part of our present day to day life. From cellular mobile to satellite or WiMAX to Radio Astronomy, everywhere high-speed wireless data communication is in increasing demand, which was started by Maxwell, Hertz, and other eminent scientists. One of the basic advantages of wireless communication is the non-requirement of data transmission medium between transmitting antenna and receiving antenna. Since Marconi’s invention of radio devices, its emergence as broadcast radio to recent technology developments has made advanced antenna systems (ASS) a viable option for multi-user, multiple-input, multiple-output technology (MU-MIMO) deployments in 5G-NR wireless networks. In this chapter, authors have presented different types of antenna structures which are suitable for massive array applications (more than 8 channels), which have been investigated by the authors. Presently, microstrip-based antenna and antenna arrays are used widely, but due to their high fabrication cost and limitation of power handling capacity, investigations on dielectric antenna (travelling wave type) were carried out which provided ultra-wide band nature suitable for ASS in 5G Mobile Network in sub-6 GHz band.
