Abstract: An antenna, in particular for a mobile communication cell site, has radiators, a reflector, a first layer, a second layer, a third layer, and at least one phase shifter with at least one delay line and a shifting device. The radiators are mounted at the front side of the first layer, and the reflector for the radiators is provided by one of the layers. The second layer comprises a cutout extending vertically through the second layer, the cutout being closed to the front by the first layer and to the rear by the third layer forming a cavity. The delay line is arranged within a vertical projection of the cavity, and the shifting device comprises a shifting portion arranged in the cavity covering the delay line at least partly.

Abstract: A mobile radio antenna includes a complete reflector is formed as one piece or by or connected to the at least one or more reflectors, or comprises at least one or more reflectors. The complete reflector comprises on the two outer longitudinal sides thereof extending in the longitudinal direction a first shield wall which shields the first and/or passive component space and/or distribution space, and a second shield wall connects directly or indirectly to the first shield wall. The two second shield walls extending on the longitudinal sides of the complete reflector protrude in the backwards direction of the antenna across a mounting plane or a section plane along which plane the first or passive component space and/or distribution space is separated or divided from the second or active component space.
