Patent ID: 8779986

Claim:
A wideband antenna, comprising: a grounding element; a feed-in terminal; a first radiating unit, electrically connected to the feed-in terminal and extending from the feed-in terminal toward a first direction, for transmitting and receiving wireless signals in a first frequency band; a second radiating unit, electrically connected to the feed-in terminal, extending from the feed-in terminal toward a second direction, and comprising a meander-shaped element, for transmitting and receiving wireless signals in a second frequency band; and a third radiating unit, electrically connected to the grounding element at an end of the third radiating unit, extending from the grounding element toward the first radiating unit and the second radiating unit, and having one segment parallel to the meander-shaped element, for coupling the meander-shaped element, so as to transmit and receive wireless signals in a third frequency band; wherein a length of the third radiating unit from the end connected to the grounding element to the other end is greater than a length of the first radiating unit, and a long segment of the meander-shaped element is parallel to the second direction.
