N2 - This paper introduces a new design methodology to achieve at least ± 90° scanning half-power beamwidth (HPBW) coverage for linear millimeter-wave (mm-Wave) antenna arrays. The method is to integrate a universally applicable and low-cost slim high dielectric-constant superstrate (HDS)-mimic metasurface above conventional antenna arrays such as patch, dipole and loop arrays. The HDS-mimic metasurface can effectively broaden the beamwdith of array element pattern. Moreover, it serves as transmitting surface when the beam is scanned at the broadside directional and wave guided surface when scanned at large angle. Thus, ultrawide angle beam scanning is realized. Three distinct design examples are presented to illustrate the design guidelines and considerations. With attractive features as low-cost, high integration, universal applicability and more than ± 90° scanning HPBW coverage, the design method is anticipated to find extensive applications in mm-Wave phased array technologies for wireless communication and radar systems.
