Claim:
1. An antenna, comprising: a first radiation element; a second radiation element having one end thereof connected with said first radiation element, said second radiation element comprising a vertical section, a first coupling section and a second coupling section, said vertical section having two opposite ends thereof respectively connected with said first radiation element and said first coupling section in a perpendicular manner relative to said first radiation element and said first coupling section, said second coupling section having one end thereof connected with said first coupling section, said first coupling section and said second coupling section having a respective top side thereof spaced from and facing toward said first radiation element; a third radiation element comprising a first connection section, a second connection section and a third connection section, said first connection section having one end thereof connected with an opposite end of said second radiation element, said first connection section being kept perpendicular relative to said second radiation element, said second connection section having one end thereof connected with an opposite end of said first connection section, said third connection section being connected with said second connection section and located at an internal side of said second connection section and abutted against an opposite end of said second connection section, said third connection section being received a feeding signal, wherein a line width of said first connection section is about 1.5 to 3 times over the line width of said second coupling section; a short-circuit portion located at an external side of said second connection section of said third radiation element, and having a first segment and a second segment, said first segment connected with said second connection section, and kept perpendicular relative to said second connection section, said second segment connected with said first segment, and kept perpendicular relative to said first segment; and a ground plane connected with said second segment of said short-circuit portion.
