ABSTRACT:
The disclosure discloses a triple-band antenna including a feed line, a first radiating body, a second radiating body and a grounding sheet. The first radiating body is a rectangular sheet. One end of the first radiating body is electrically connected with the end of the feed line. The second radiating body includes three parallel bar shape sheets extending from the first radiating body and surrounded by the first radiating body, and both share the feed line. The grounding sheet is disposed beside the feed line. The first radiating body and the second radiating body of the triple-band antenna generate three resonance frequencies according to the radio frequency received by the feed line to allow the triple-band antenna work under three different operating frequencies.
