Multi-band antenna

Abstract

A multi-band antenna () includes a grounding element () extending along a horizontal direction and including a side edge () with a connecting point () and a grounding point () distanced from the connecting point by a length, a first radiating element () disposed above and parallel to the grounding element (), a second radiating element () apart from the first radiating element and extending upwardly from the side edge of the grounding portion, a connecting element () located between the first radiating element and the grounding element, a feeding point () disposed on the connecting element (), and a feeding line () including an inner conductor () connected to the feeding point and an outer conductor () 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 () 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 () together with said second radiating element and said connecting element.
