Patent ID: 8350775

Claim:
An antenna arrangement, comprising: at least one radiator assembly comprising a vector dipole array; a supporting structure disposed beneath the vector dipole array, supporting and configured for feeding RF energy to the vector dipole array, a reflector arrangement comprising an electrically conductive reflector surface, and at least one electrically conductive longitudinal or transverse web, the reflector arrangement further comprising a printed circuit board, an electrically conductive ground plane structure being disposed on said printed circuit board, the reflector arrangement further comprising a reflector frame comprising a coupling surface that runs parallel to the printed circuit board ground plane structure, the coupling surface being capacitively coupled to the ground plane structure and mechanically and electrically-galvanically connected to the at least one longitudinal or transverse web; the coupling surface defining therein a window through which the printed circuit board ground plane structure is exposed to the vector dipole array to thereby capactively couple, through the window, the printed circuit board ground plane structure with the vector dipole array, the supporting structure holding and supporting the at least one vector dipole array radiator assembly above the printed circuit board in the region of the window.
