An antenna comprising a network of arrayed radiating elements, a first reflective means comprising a flat central part upon which are disposed the radiating elements and longitudinally folded edges on either side of the array of elements, and at least one second reflective means which is a choke reflector disposed outside of the space separating the radiating elements of the reflector's folded edge. The second reflective means is separated from the first reflective means by a layer of dielectric material in order to connect it to the first reflective means by way of capacitive coupling.

Choke reflector antenna

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.
