ABSTRACT:
Disclosed herein is an antenna for portable wireless communication apparatuses. The antenna for portable wireless communication apparatuses includes an antenna element provided on its outer surface with a conductor on which a plurality of openings are formed. The outer portion of the interior of the conductor is filled with a dielectric material. This antenna element is connected in parallel with a linear radiator in an insulated state, thereby radiating electromagnetic waves and at the same time being capable of adjusting the radiated amount and direction of the electromagnetic waves.
