Abstract: A tremendous increase in the achievable data rates will be expected from the fifth generation (5G) wireless standard. This increase (almost x1000) will be spread between the antenna systems, network architecture, radio front ends, and signal structure. Multiple-input-multiple-output (MIMO) technology has been utilized heavily in 4G terminals and will continue to serve as a key technology in 5G ones as it provides data rate increase without power or bandwidth increase. In addition, backward compatibility with 4G dictates the use of MIMO in 5G enabled terminals. The use of millimeter-wave (mm-wave) bands is essential to provide high data throughputs due to the excess bandwidth they offer and has already been approved for 5G use. In this talk, technology trends and the features of 5G wireless standards will be presented. Then some of the major enabling technologies for 5G such as massive MIMO (MaMi) and mm-wave will be highlighted along with their features and applications. Challenges in the design of antenna systems for these enabling technologies will be discussed in terms of complexity, size, etc. Specifications and design guidelines will follow. Several metallic based mm-wave MIMO antennas, dielectric-resonator antennas (DRAs), active integrated and reconfigurable MIMO Antennas will be discussed. In addition, MaMi arrays with beam-steering capabilities will be presented. The concept and modeling of multi-functional antenna systems and integrated 4G/5G handset antenna solutions will be shown with real examples.
