Abstract
An antenna arrangement for multi frequency band operation makes it possible to reduce the number of antennae on a base station antenna mast. The antenna includes a first radiator element for operation in a first frequency band and a second radiator element for operation in a second frequency band. The second element is arranged in a different plane from said first element. The first element is placed so that it symmetrically overlaps the second element. A conductive ground plane is provided with a device for feeding energy to the radiator elements, and the radiator elements are arranged for providing dual polarization. An array antenna includes groups of high and low frequency elements.
