The purpose of this paper is to examine some these challenges from the point of view of antenna design for 5G. These include: low-cost and low-loss phase shifters for scanning array antennas; low-profile high gain aperture; wideband circularly polarized antenna elements for arrays; wide-angle beam scan .
