Abstract (en)

[origin: WO9621254A1] An improved antenna for a portable radio communication device including a first elongate electrically conductive member (10) having opposed first and second ends, the first end adapted to be mounted in electrical communication to a radio communication device (18). A radiation field pattern is generated by radiation emitted by the first elongate electrically conductive member (10) and the radio communication device (18) during radio transmission, the radiation field pattern having maximum intensity at a first location. Means (24) for increasing radiation resistance is mounted to the first electrically conductive member at an optimized position at generally the second end of the first member, whereby the radiation field pattern maximum intensity is shifted from the first location to a second location closer to the second end of the elongate member (10), and near field intensity of the radiation field pattern at the first location is reduced over an operational bandwidth of the radio communication device (18).
