Abstract:
In an antenna array comprising: a reflector, at least two radiators arranged vertically one above the other, which are located in front of the reflector, and a common feed network with a defined power and phase that feeds the at least two radiators, an arrangement comprising:at least one first primary radiator structure of a first type having a predetermined polarization; at least one second primary radiator structure of a second type arranged at a distance vertically above the first primary radiator structure, said second primary radiator structure having the same predetermined polarization as the first primary radiator structure, the at least one first primary radiator structure of the first type having a different horizontal half-value width than the at least one second primary radiator structure of the second type, and the at least one first radiator structure of the first type having a physical design that is different from the physical design of the at least one second radiator structure of the second type.
