Antenna system with radiating element fed via side region

An antenna system comprising:

• a dual-polarized radiating element extending generally in a first direction parallel or substantially parallel to a reflector of the antenna system, wherein the dual-polarized radiating element is configured to emit an electromagnetic wave;
• a feeding structure extending generally in a second direction having a component perpendicular to the reflector of the antenna system, wherein the feeding structure is spaced apart, in relation to the first direction, from a center portion of the dual-polarized radiating element;
• a coupling feeding line electrically coupling the center portion of the dual-polarized radiating element with the feeding structure for feeding an electrical signal via the feeding structure through the coupling feeding line to the center portion of the dual-polarized radiating element;
• and
• a dielectric substrate at least partially extending parallel to the first direction,
• wherein the dual-polarized radiating element is at least partially arranged on a first side of the dielectric substrate,
• wherein the coupling feeding line is at least partially arranged on one or both of the first side and a second side of the dielectric substrate, wherein the first side faces towards a direction opposite to a direction towards which the second side faces.
