| 摘要 |
<p>The invention relates to a dual polarised radiating element (1) for a cellular base station antenna, comprising:
-a reflector surface (21) for reflecting radiation energy,
-four radiating monopoles (4a to 4d) distributed around an aperture area (9), each radiating monopole comprising a footing (42a to 42d) protruding from said reflector surface and a flange (41a to 42d) 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,
wherein it further comprises:
-four element feeds (5a to 5d), each capacitively coupled to a respective monopole and protruding radially therefrom within the aperture area (8);
-powering means (6ac, 6bd, 7a to 7d, 7ac, 7bd) connected to the element feeds.</p> |
