ABSTRACT:
A dual band antenna has a ground portion, a first radiating conductor spaced from one side of the ground portion, a second radiating conductor connected between one end of the first radiating conductor and the ground portion, a third radiating conductor connected on the other end of the first radiating conductor, a fourth radiating conductor extended from the third radiating conductor, a parasitic element arranged to close to the second radiating conductor and connected to the ground portion and a feeding cable connected to the free end of the third radiating conductor. When the dual band antenna operates, the first, second and third radiating conductors obtain a first wireless location area network bandwidth covering 2.4 GHz to 2.5 GHz, and the third radiating conductor, the fourth radiating conductor and the parasitic element obtain a second wireless location area network bandwidth covering 4.9 GHz to 5.87 GHz.
