1. A beam switching antenna system comprising:

  • an antenna element for transmitting and receiving a beam;

    a dielectric body surrounding said antenna element;

    a plurality of conductive reflectors facing a lateral outside of said dielectric body, each of said plurality of conductive reflectors comprising an upper conductive reflector having a length of λ

    /8 and a lower conductive reflector having a length of λ

    /16, where λ

    is a wavelength of a radio wave in air; and

    a ground switch circuit connected to each of said plurality of conductive reflectors,wherein the dielectric body comprises a plurality of circumferential planar surfaces corresponding to the plurality of conductive reflectors.
