MULTI-BAND ANTENNA STRUCTURE

摘要

The instant disclosure relates to a multi-band antenna structure for accepting a feed signal. The antenna structure includes a grounding portion, a radiating portion, and a tuning portion. The radiating portion is spaced apart from the grounding portion and disposed on one side thereof. The radiating portion has a first and a second radiating segments interconnected perpendicularly. The tuning portion is connected between the first radiating segment and the grounding portion. The tuning portion has a hairpin segment and a grounding segment. The hairpin segment is substantially U-shaped and one end thereof is connected to one end of the first radiating segment proximate to the grounding portion. The opposite ends of the grounding segment are connected to the other end of the hairpin segment and the grounding portion. The connecting location between the first radiating segment and the hairpin segment is used for accepting the feed signal.
