The fifth generation (5G) network communication systems operate in the millimeter waves and are expected to provide a much higher data rate multi-gigabit range, which is impossible achieve using current wireless services, including sub-6 GHz band. In this work, we briefly review several existing designs of millimeter-wave phased arrays for 5G applications, beginning with low-profile antenna array that either fixed beam or scan only one plane. We then move on offer two-dimensional (2D) capability, highly desirable majority applications. Next, main body paper, discuss two different strategies designing scanning arrays, both circumvent use conventional phase shifters scanning. note it search alternatives range because legacy lossy costly; furthermore, such as active shifters, include radio frequency amplifiers, expensive power-hungry. Given backdrop, propose potential desired 2D performance range. first these Luneburg lens, excited by waveguide microstrip patch realize capability. second design, turn phased-array shifter replaced switchable PIN diodes varactor diodes, inserted between radiating slots shifts Finally, approaches enhance gain modifying configurations. describe novel techniques realizing one-dimensional (1D) scans reconfigurable metasurface type panels.
