Abstract
The present disclosure relates to a dual-polarized antenna comprising a dipole radiator, a resonant cavity radiator and a reflector. The resonant cavity radiator is arranged below the reflector and radiates through a slot in the reflector, and the dipole radiator is arranged above the reflector, with a signal line and/or a carrier of the dipole radiator extending through the slot.
Claims16
A dual-polarized antenna comprising:
- a dipole radiator;
- a resonant cavity radiator;
- and
- a reflector,
- wherein the resonant cavity radiator is arranged below the reflector and radiates through a slot in the reflector, and wherein the dipole radiator is arranged above the reflector, with a signal line and a carrier of the dipole radiator extending through the slot;
- wherein at least one conductor of an excitation structure of the resonant cavity radiator extends through an opening of the carrier, the opening of the carrier comprising an opening in a printed circuit board carrying the dipole radiator and the signal lines of the dipole radiator or in a sheet metal structure, the opening of the carrier being closed or open to the outside, and wherein the excitation structure and both conductors of the excitation structure of the resonant cavity radiator extend into a cavity through a sidewall of the cavity of the resonant cavity radiator.

An antenna array comprising at least one dual-polarized antenna and at least one further antenna, wherein the at least one dual-polarized antenna comprises:
- a dipole radiator;
- a resonant cavity radiator;
- and
- a reflector,
- wherein the resonant cavity radiator is arranged below the reflector and radiates through a slot in the reflector, and wherein the dipole radiator is arranged above the reflector, with a signal line and a carrier of the dipole radiator extending through the slot;
- wherein at least one conductor of an excitation structure of the resonant cavity radiator extends through an opening of the carrier, the opening of the carrier comprising an opening in a printed circuit board carrying the dipole radiator and the signal lines of the dipole radiator or in a sheet metal structure, the opening of the carrier being closed or open to the outside, and wherein the excitation structure and both conductors of the excitation structure of the resonant cavity radiator extend into a cavity through a sidewall of the cavity of the resonant cavity radiator.
