ABSTRACT:
It is an object to provide a portable wireless communication apparatus antenna, which is slidable relative to a casing and completely retractable in the casing and which has the same wideband characteristic when it is retracted as when it is extended. The antenna comprises a first antenna element slidable relative to the casing and a second antenna element fixedly disposed in the casing, wherein the lower end part of the first antenna element when it is retracted and the upper end part of the second antenna element are arranged to be adjacent to each other, thereby coupling the capacitance to form an antenna system as a unit.
