摘要:
The subject of this invention is a multiband antenna radiating element comprising a first pair of cross-polarization dipoles each of which comprises two collinear conducting arms, whereby the four conducting arms define a first radiating plane corresponding to a low frequency band. The radiating element also consists of at least a second pair of cross-polarization dipoles each of which comprises two collinear conducting arms, whereby the four conducting arms define a second radiating plan corresponding to a higher frequency band. The first and second radiating planes are parallel; the second radiating plane is positioned above the first from which it is electrically insulated and the surface of the first radiating plane covering the conducting arms of the first pair of dipoles is larger than the surface of the second radiating plane covering the conducting arms of the second pair of dipoles. The first radiating plane can be defined by a first pair of dual cross-polarization dipoles or one printed circuit dipole and the second radiating plane can be defined by a second pair of dipoles chosen from cross dipoles, butterfly dipoles and printed circuit dipoles.

A dual-polarization radiating element for a multiband antenna comprises a support with a high dielectric constant whose shape is roughly cylindrical, having an axis of revolution, at least a first and a second pair of dipoles printed on a first surface of the support, the dipoles of the first pair being roughly orthogonal to the dipoles of the second pair, and conductive lines, to feed each dipole, printed onto a second surface of the support. The support is placed on a flat reflector, with the cylindrical support's axis of revolution being perpendicular to the plane of the reflector.
