Abstract
A dual-band antenna includes a substrate, a first antenna assembly, an isolation metal sheet, and a second antenna assembly. The first antenna assembly includes a first and a second planar inverted-F antennas, which are symmetric with each other and disposed on the first side of the substrate. The first planar inverted-F antenna includes a first radiation portion and a first ground portion. The second planar inverted-F antenna includes a second radiation portion and a second ground portion. The isolation metal sheet is coupled between the first ground portion and the second ground portion. The second antenna assembly includes a third and a fourth antennas, which are coupled to the first and the second ground portions, respectively, and are symmetric with each other and are disposed on the second side of the substrate. The first and the second antenna assemblies are operated at a first and a second frequencies, respectively.
