ANTENNA Russian patent published in 1995 - IPC

FIELD: radio communication. SUBSTANCE: antenna includes dipole set above horizontal grounded screen manufactured in the form of tube. Current-carrying conductors are connected to central conductor of coaxial feeder which outer conductor is linked to grounded screen. Cylindrical spiral connected to base of metal pin mounted in vertex of dipole is installed along axis of screen. Noninductive resistor is placed between conductive cylindrical spiral and grounded screen. Conductive element is made in the form of additional section of coaxial feeder with outer conductor formed by two cylinders of equal length. Additional conductors with insulation coat are positioned inside conductive cylindrical spiral and are coupled at one lead to noninductive resistor. Description specified relative dimensions of elements of antenna. EFFECT: enhanced functional capabilities. 2 dwg, 1 tbl
