ABSTRACT:
A hexagonal array structure of a dielectric rod for shaping a flat-topped element pattern (FTEP) is provided. The hexagonal structure of dielectric rods forming a flat-topped element pattern (FTEP) includes: a center element for forming a unit radiation pattern of the FTEP through an electromagnetic wave mutual coupling by receiving a polarization signal of a basic mode; a plurality of first ring elements arranged at vertexes of a regular hexagon based on the center element for forming the unit radiation pattern by electromagnetic wave mutual coupling with the center element and an electromagnetic wave; and a circular waveguide array supporting unit for supporting the center element and the plurality of first ring elements.
