Patent ID: 8779989

Claim:
A wideband antenna comprising: a grounding unit electrically connected to a ground; a feed-in source for transmitting and receiving radio frequency signals; a first radiating body comprising: a first radiating unit extending along a first direction; a second radiating unit extending along a second direction opposite to the first direction; and a conducting unit extending along a third direction, and comprising one end electrically connected between the first radiating unit and the second radiating unit and another end electrically connected to the feed-in source; and a second radiating body comprising: a short-circuit unit electrically connected to the grounding unit; a third radiating unit electrically connected to the short-circuit unit, and comprising a branch extending along the third direction to generate a coupling connection effect with the conducting unit via a first distance; wherein the first direction is approximately perpendicular to the third direction, and a distance between a side of the second radiating body facing the grounding unit and the grounding unit is smaller than a distance between a side of the first radiating unit facing the grounding unit and the grounding unit, such that a combination of the first radiating body and the grounding unit externally surrounds the second radiating body.
