US Patent 9246236 Dual-polarization radiating element of a multiband antenna

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.
