Abstract
A dual band antenna assembly is described to include a pair of dual band active radiating elements disposed upon a dielectric substrate. A pair of LC traps and conductor elements are electrically coupled to the radiating conductor elements to provide dual band resonance for cellular telephone and PCS device bandwidth ranges. Additional performance may be achieved with parasitic reflector and director elements. The multi-element directional antenna finds particular applicability for in-vehicle and wireless communication use.
