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.

A crossed polarization antenna system including a substantially flat and rectangular reflector and at least one radiating cell carried by the reflector, each cell including at least two first conductor elements assembled tail-to-tail and energized by a first external power supply forming a first dipole. Each radiating cell includes two second conductor elements mounted in exactly the same way as the first elements and energized by a second external power supply forming a second dipole. The conductor elements are V-shape bent elements with the second elements mounted orthogonally to the first elements. Applications include mobile telephones.
