Abstract
A multi-element radio antenna assembly is described. The antenna assembly includes a ground plane element having an array of conductor elements disposed thereon. A pair of LC trap structures 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 use.
