Abstract
A multi-broad band antenna including a first radiating body, a second radiating body, a third radiating body, a grounding plate and many short-circuit elements is provided. The first radiating body excites a first resonant mode, such that the multi-broad band antenna has a high frequency wide bandwidth. The second radiating body excites a second resonant mode, such that the multi-broad band antenna has a middle frequency wide bandwidth. The third radiating body excites a third resonant mode, such that the multi-broad band antenna has a low frequency wide bandwidth. A number of short-circuit elements connect the first radiating body, the second radiating body and the third radiating body to the grounding plate respectively. The radiation patterns of the first resonant mode, the second resonant mode and the third resonant mode do not disturb each other.
