Abstract
A dual-band antenna has a first meandering portion, a second meandering portion and a connection portion defining two ends. The first meandering portion and the second meandering portion have different length. One end of the first meandering portion connects one end of the second meandering portion. The other end of the first meandering portion connects one end of the connection portion. The other end of the second meandering portion connects a feeding portion. The other end of the connection portion connects a ground portion. The feeding portion, the second meandering portion, the first meandering portion and the connection portion obtain an electrical resonance corresponding to a first frequency range. The second meandering portion obtains an electrical resonance corresponding to a second frequency range.
