Abstract
A simple internal or partly internal antenna system for optimizing the radiation pattern from hand held wireless communications devices HHWCD such as hand-held data devices and cellular telephones is disclosed. The antenna system consists of an essentially internal or partly internal asymmetrical dipole with quarter-wave resonator section and radiating planar section, in conjunction with a planar parasitic director element. The radiating planar section may be the ground traces of the HHWCDs printed wiring board PWB. The antenna system provides for single or multiple frequency band operation.
