1. A broadband antenna comprising:
an electrically conductive circular metal plate having a cylindrical passive radiator element mounted at a center point of a top surface of said plate, a plurality of supplementary radiator elements mounted in an evenly spaced manner around a concentric circle pattern spaced and coaxial from said center point, adjacent supplementary radiator elements being spaced not less than half the wavelength of a predetermined minimum frequency of radio wave band of said antenna; a plurality of passive director elements mounted in an evenly spaced manner around periphery of said plate, and said supplementary radiator elements being connected in one point through signal input supply wires of equal length to an antenna switch controlled by a processor, and signal outputs of said antenna switch being connected to an adder by equal length output wires, whereby said antenna has an omnidirectional radiation pattern in an azimuth plane.
