1. A radiation structure for operation over a range of frequencies comprising:

  • a one piece radiating element in the form of a wide, thin electrical conductor, said conductor having first, second and third sections;

    said first section adapted for connection to a feed circuit;

    said second section connecting said first and third sections and spacing them apart;

    said conductor having an elongated slot through its thin dimension direction which extends at least from within said first section to within said third section to separate said second section into first and second spaced apart balanced transmission line members;

    said first section connecting said first transmission line member to said second transmission line member;

    said first section having a length from said first transmission line member to said second transmission line member which is substantially an odd integer multiple of one-half wavelength at a frequency in said range of frequencies when said element is connected to said feed circuit;

    said third section comprising a dipole electrically coupled to said first section by said balanced transmission line members of said second section; and

    said element being free of ground conductors extending parallel to said second and third sections.
