1. A reflector sub-assembly for an antenna assembly configured to support Frequency Division Duplex, FDD, and Time Division Duplex, TDD, modes of operation, the reflector sub-assembly comprising:
a reflector defining at least one reflector opening;
at least one first printed circuit board, PCB, arranged to cover the at least one reflector opening so as to prevent electromagnetic radiation from passing through the at least one reflector opening, the first PCB having
a first PCB side directed towards the reflector and having a metallic layer thereon, and
a second PCB side directed away from the reflector and comprising one or more first electric lines;
an array of first radiators to support a TDD mode, the first radiators extending through the at least one reflector opening in the reflector and having
a feeding end directed towards the at least one first PCB and electrically connected to at least one of the one or more first electric lines; and
a distant end facing away from the at least one first PCB and carrying at least one first radiating element; and
one or more second radiators to support an FDD mode, the one or more second radiators having
a feeding end positioned, in a planar projection, within the array of first radiators; and
a distant end facing away from the reflector and carrying at least one second radiating element.
