ANTENNA SYSTEM WITH RADIATING ELEMENT FED VIA SIDE REGION

We generally describe an antenna system (200, 300, 400, 500) comprising a dual-polarized radiating element (202, 302, 402, 600, 700) extending generally in a first direction (212) parallel or substantially parallel to a reflector (204) of the antenna system (200, 300, 400, 500). The dual-polarized radiating element (202, 302, 402, 600, 700) is configured to emit an electromagnetic wave. The antenna system further comprises a feeding structure (206) extending generally in a second direction (214) having a component perpendicular to the reflector (204) of the antenna system (200, 300, 400, 500). The feeding structure (206) is spaced apart, in relation to the first direction (212), from a center portion (203, 303, 403, 603, 703) of the dual-polarized radiating element (202, 302, 402, 600, 700). The antenna system further comprises a coupling feeding line (210, 312, 404a, 404b, 404c, 404d, 602, 702) electrically coupling the center portion (203, 303, 403, 603, 703) of the dual- polarized radiating element (202, 302, 402, 600, 700) with the feeding structure (206) for feeding an electrical signal via the feeding structure (206) through the coupling feeding line (210, 312, 404a, 404b, 404c, 404d, 602, 702) to the center portion (203, 303, 403, 603, 703) of the dual-polarized radiating element (202, 302, 402, 600, 700). The antenna system further comprises a dielectric substrate (301) at least partially extending parallel to the first direction (212). The dual-polarized radiating element (202, 302, 402, 600, 700) is at least partially arranged on a first side (301a) of the dielectric substrate (301). The coupling feeding line (210, 312, 404a, 404b, 404c, 404d, 602, 702) is at least partially arranged on one or both of the first side (301a) and a second side (301b) of the dielectric substrate (301), wherein the first side (301a) faces towards a direction opposite to a direction towards which the second side (301b) faces. L'invention concerne de manière générale un système d'antenne (200, 300, 400, 500) comprenant un élément rayonnant à double polarisation (202, 302, 402, 600, 700) s'étendant généralement dans une première direction (212) parallèle ou sensiblement parallèle à un réflecteur (204) du système d'antenne (200, 300, 400, 500). L'élément rayonnant à double polarisation (202, 302, 402, 600, 700) est configuré pour émettre une onde électromagnétique. Le système d'antenne comprend en outre une structure d'alimentation (206) s'étendant généralement dans une s
