A multi-band antenna (1) includes a grounding element (10) extending along a horizontal direction and including a side edge (101) with a connecting point (102) and a grounding point (103) distanced from the connecting point by a length, a first radiating element (11) disposed above and parallel to the grounding element (10), a second radiating element (12) apart from the first radiating element and extending upwardly from the side edge of the grounding portion, a connecting element (13) located between the first radiating element and the grounding element, a feeding point (134) disposed on the connecting element (13), and a feeding line (14) including an inner conductor (141) connected to the feeding point and an outer conductor (142) connected to the grounding point. The first radiating element operates in a first frequency band. The second radiating element defines a L-shaped configuration in a side view and operates in a second frequency band. The connecting element (13) includes a first end linked to an end of said first radiating element and a second end connecting to said connecting point of the grounding element. Said first radiating element extends from said first end of the connecting element along a direction away from the second radiating element, and forms a slot (15) together with said second radiating element and said connecting element.
