Abstract: A radiating element of a broadband antenna comprises a foot supporting first and second components disposed in a first plane which are two half-wavelength symmetrically fed dipoles generating a linear dual polarization, both comprising two arms. According to the invention, the radiating element further comprises at least one third component chosen from among a dipole or a patch disposed within a second plane placed above the first plane, and each of the components is made up of a volume fractal pattern.

Abstract: An antenna, intended to transmit and receive radio waves within a given frequency band, comprises at least one radiating element, placed on a flat reflector, comprising a radiating device disposed within a plane parallel to the reflector's plane, at least one conductive line feeding the radiating element, at least one parasitic element disposed above the radiating element, which comprises a two-dimensional base belonging to a plane parallel to the radiating device's plan, associated with a third dimension that gives it a volumic shape.

Abstract: The object of the present invention is an antenna system comprising at least one first antenna and at least one second antenna, each comprising spaced-apart radiating elements aligned along the longitudinal axis of the antenna, the second antenna being disposed a short distance away from, and parallel to, the first antenna, characterized in that the plane perpendicular to the longitudinal axis passing through a radiating element of the first antenna is displaced in the direction of the longitudinal axis with respect to the plane perpendicular to the longitudinal axis passing through the radiating element of the second antenna which is closest to it.

Abstract: A polarized antenna for sending and receiving polarized radio frequency signals is disclosed which includes a dipole and a reflector plate. The dipole is formed as a single part including the radiating arms and feeding structures, thereby requiring minimum assembly. This dipole can be formed by molding conventional materials, such as copper, aluminum, and plastic, which can then be plated. The feeding structure through which the cable passes features a slotted aperture. The impedance of the dipole is based on the width of these apertures and the size of the cable conductor. By having a single-body construction, the dipole of the present invention provides, good impedance, low intermodulation distortion, good port-to-port isolation, and good pattern purity.
