ABSTRACT:
A dual band antenna assembly includes a radiating metal strip fabricated on a baseboard. The radiating metal strip includes a winding strip section having a heading end and a tail end, a connected strip section having one connecting end coupled integrally to the tail end of the winding strip section and the other connecting end, a lump-like strip section having a first terminal end serving as a feeding pin and a second terminal end coupled integrally to the other connecting end of the connected strip section. A first signal-working band is defined when a current path flows through the feeding pin and the second terminal end of the lump-like strip section to generate a first resonance. A second signal-working band is defined when a current path flows through the lump-like strip section, the connected strip section and the winding strip section to generate a second resonance.
