1. An apparatus comprising:
- an antenna occupying at least a first plane;
a conductive structure that is galvanically isolated from the antenna but is arranged to be parasitically fed by the antenna, the conductive structure having a slot and occupying at least a second plane different to but adjacent the first plane, wherein the conductive structure forms at least part of an external housing for a hand-portable electronic apparatus, wherein the antenna is an internal antenna located inside the housing, wherein the housing has a face bounded by edges and the slot is positioned wholly within the face, and wherein the antenna is positioned adjacent the slot.
