Abstract
This chapter specifies a concise review of recent research and development in the context of reconfigurable antenna. An attempt has been made to elaborate the distinct types of the 5G reconfigurable antenna with vital technique of the reconfigurability since from its evolution. Several significant prospects of 5G antennas are described to enhance antenna characteristics. Some basic concepts, theories, advantages, disadvantages, applications, and requirements of the Adaptive and MIMO antenna are discussed along with historical accomplishments. These systems can be the promising candidates for next generation network. This paper also provides a futuristic glimpse of UM-MIMO for 6G purpose.
