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.

Dual-polarization radiating element for broadband antenna

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.
