Abstract:
1. An antenna structure, comprising: an electrically conductive enclosure of the antenna, the electrically conductive enclosure comprising: an electrically conductive enclosure with an aperture formed in an end thereof; and wherein a size of the aperture is defined by a first distance between two sides of the aperture; an electrically conductive cover comprising: a feed layer located between the electrically conductive enclosure and the first portion of the electrically conductive cover, the feed layer being arranged to carry electrically conductive track, wherein a radiating portion of the electrically conductive track is configured to be in registration with the slot; at least one dielectric material between the electrically conductive enclosure and the electrically conductive cover; wherein the end wall of the electrically conductive enclosure defines a plane of the aperture, and wherein the side walls of the electrically conductive enclosure comprises a fencing portion, and the fencing portion extends beyond the plane of the aperture so as to form a gap between the fencing portion and an internal face of the cover, wherein the gap is configured to improve isolation provided by the fencing structure.
