Patent ID: 8416141

Claim:
Dual polarised radiating element for a cellular base station antenna, comprising: a reflector surface for reflecting radiation energy, four radiating monopoles distributed circumferentially around an aperture area prescribed by the inner perimeter of the four radiating monopoles and in which an electric field is generated that forms a magnetic source, each radiating monopole comprising a footing protruding from said reflector surface and a flange located above the reflector surface and protruding from said footing radially towards an outside, the flanges from adjacent monopoles extending radially perpendicular to each other, four element feeds comprising each a footing portion and a flange portion connected to an upper part of the footing portion and perpendicular thereto, where each footing portion is capacitively coupled to a respective radiating monopole at a level of its footing and each flange portion protruding radially from the respective radiating monopole within the aperture area, a power source connected to the four element feeds.
