Dual polarised radiating element for cellular base station antennas
Abstract:
The invention relates to a dual polarized radiating element for a cellular base station antenna, comprising a reflector surface for reflecting radiation energy, four radiating monopoles distributed around an aperture area, 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 the outside, the flanges from adjacent monopoles extending radially perpendicular to each other. The element further comprises four element feeds, each capacitively coupled to a respective monopole and protruding radially therefrom within the aperture area, and powering means connected to the element feeds.
